This document summarizes and analyzes a research article about a new organizational language called social activity method (SAM). The summary includes:
1) The author introduces SAM and illustrates some of its applications, including a new scheme for analyzing how one activity recontextualizes another.
2) A key claim of SAM is that all knowledge is mediated through interpretation and there is no direct access to concepts, undermining the idea that research uncovers pre-existing objects or structures.
3) The author argues research should present languages that are self-referential rather than claiming to represent external realities, to avoid pushing representations into the empirical world in a misleading way.
An introduction to compositional models in distributional semanticsAndre Freitas
The document provides an overview of compositional distributional semantic models, which aim to develop principled and effective semantic models for real-world language use. It discusses using large corpora to extract distributional representations of word meanings and developing compositional models that combine these representations according to syntactic structure. Both additive and multiplicative mixture models as well as function-based models are described. Challenges including lack of training data and computational complexity are also outlined.
Time underlies many interesting human behaviors. Thus, the question of
how to represent time in connectionist models is very important. One
approach is to represent time implicitly by its effects on processing rather
than explicitly (as in a spatial representation). The current report develops
a proposal along these lines first described by Jordan (1986) which
involves the use of recurrent links in order to provide networks with a
dynamic memory. In this approach, hidden unit patterns are fed back to
themselves; the internal representations which develop thus reflect task
demands in the context of prior internal states. A set of simulations is
reported which range from relatively simple problems (temporal version
of XOR) to discovering syntactic/semantic features for words. The
networks are able to learn interesting internal representations which
incorporate task demands with memory demands; indeed, in this approach
the notion of memory is inextricably bound up with task processing. These
representations reveal a rich structure, which allows them to be highly
context-dependent while also expressing generalizations across classes of
items. These representations suggest a method for representing lexical
categories and the type/token distinction.
Compositional distributional models of meaning (CDMs) aim to unify the two prominent semantic paradigms in natural language: The type-logical compositional approach of formal semantics, and the quantitative perspective of vector space models of meaning. This presentation gives an overview of state-of-the-art research on the field. We review three generic classes of CDMs: vector mixtures, tensor-based models, and deep-learning models.
The spread and abundance of electronic documents requires automatic techniques for extracting useful information from the text they contain. The availability of conceptual taxonomies can be of great help, but manually building them is a complex and costly task. Building on previous work, we propose a technique to automatically extract conceptual graphs from text and reason with them. Since automated learning of taxonomies needs to be robust with respect to missing or partial knowledge and flexible with respect to noise, this work proposes a way to deal with these problems. The case of poor data/sparse concepts is tackled by finding generalizations among disjoint pieces of knowledge. Noise is
handled by introducing soft relationships among concepts rather than hard ones, and applying a probabilistic inferential setting. In particular, we propose to reason on the extracted graph using different kinds of relationships among concepts, where each arc/relationship is associated to a number that represents its likelihood among all possible worlds, and to face the problem of sparse knowledge by using generalizations among distant concepts as bridges between disjoint portions of knowledge.
Introduction to Distributional SemanticsAndre Freitas
This document provides an introduction to distributional semantics. It discusses how distributional semantic models (DSMs) represent word meanings as vectors based on their linguistic contexts in large corpora. This distributional hypothesis states that words that appear in similar contexts tend to have similar meanings. The document outlines how DSMs are built, important parameters like context type and weighting, and examples like latent semantic analysis. It also discusses how DSMs can support applications like semantic search. Finally, it introduces how compositional semantics explores representing the meanings of phrases and sentences compositionally based on the meanings of their parts.
Outline of a Multidimensional Theory of Learning by Competences: An Essay abo...inventionjournals
There are several possibilities for understanding complex and polysemic terms such as Education and Learning. In this sense, over the last 30 years a theory of learning in particular has gained enough scientific status and reliability to serve as support for the implementation and regulation of education systems around the world: it is the Theory of Learning by Competencies. This theory, however, is subject to refinements and modifications, especially when confronted with scientific models such as Metaciência Social (created by Pablo Bispo dos Santos) and Unified Field Theory (created by Albert Einstein). This paper presents an essay to discuss the possibility of creating and applying (to several objects of study) a new methodology of educational evaluation called: Holospheric Learning System.
This study investigated whether spoken words are represented at both surface and underlying abstract levels. In 6 experiments, participants heard word primes followed by word targets. Primes and targets contained flaps (neutralized allophones of /t/ and /d/). Reaction times showed evidence for both surface and underlying representations - flapped primes facilitated targets containing the same phoneme, regardless of surface form. This supports theories proposing direct access to abstract representations from surface forms.
Conceptual Spaces for Cognitive Architectures: A Lingua Franca for Different ...Antonio Lieto
We claim that Conceptual Spaces offer a lingua franca that allows to unify and generalize many aspects of the symbolic, sub-symbolic and diagrammatic approaches (by overcoming some of their typical problems) and to integrate them on a common ground. In doing so we extend and detail some of the arguments explored by Gardenfors [23] for defending the need of a conceptual, intermediate, representation level between
the symbolic and the sub-symbolic one. Additionally, we argue that Conceptual Spaces could offer a unifying framework for interpreting many kinds of diagrammatic and analogical representations. As a consequence, their adoption could also favor the integration of diagrammatical representation and

The document discusses expository text structure and its importance for students' comprehension. It provides research findings that show expository text is more difficult than narrative text for comprehension and recall. The document also presents a matrix that describes five common types of expository text structures (description, sequence, comparison/contrast, cause/effect, problem/solution), including their defining attributes, example signal words used, and potential graphic organizers to represent each structure. Finally, the document discusses strategies teachers can use to help students identify different expository text structures.
Tensor-based models of natural language semantics provide a conceptually motivated procedure to compute the meaning of a sentence, given its grammatical structure and a vectorial representation of the meaning of its parts. The main characteristic of these models is that words with relational nature, such as adjectives and verbs, become (multi-)linear maps acting on vectors representing words of atomic types, e.g. nouns and noun phrases. On the practical side, the tensor-based framework has been proved useful in a number of NLP tasks. On the theoretical side, its rigorous mathematical foundations provide a test-bed for studying compositional aspects of language at a level deeper than most practically-oriented approaches would allow; for example, mathematical structures such as Frobenius algebras and bialgebras have been used to allow the explication of functional words such as relative pronouns, to model linguistic aspects such as coordination and intonation, and to provide accounts of quantification in distributional models. Furthermore, the deep structural similarity of the framework to concepts that explain the behaviour of quantum-mechanical systems has enabled a unique perspective in approaching language-related problems, such as lexical ambiguity and entailment, by leveraging the model to the realm of density operators and complete positive maps via Selinger's CPM construction. This talk aims at providing a comprehensive introduction to this emerging field by presenting the mathematical foundations, discussing important extensions and recent work, and (time permitted) touching implementation issues and practical applications.
The document proposes a mixed approach using existing natural language processing techniques and novel techniques to automatically construct conceptual taxonomies from text. Key steps include identifying relevant concepts and attributes from text, clustering similar concepts, computing relevance weights for concepts, and generalizing concepts using WordNet. Preliminary results suggest the approach shows promise for extending and improving automatic taxonomy construction.
Extending the knowledge level of cognitive architectures with Conceptual Spac...Antonio Lieto
Extending the knowledge level of cognitive architectures with Conceptual Spaces (+ a case study with Dual-PECCS: a hybrid knowledge representation system for common sense reasoning). Talk given at Stockholm, September 2016.
The document compares two sets of operators - Michalski's knowledge transmutations from machine learning and Baker's dialogue transformations that model knowledge negotiation in dialogue. It finds some overlap between the operators but also key differences related to the number of agents involved, how strategical aspects are represented, and the relationship between uttered and internal knowledge. The authors discuss how fusing these operator sets could help model collaborative learning and develop human-machine learning systems.
Mathematics concepts originate from innate human cognitive abilities and everyday experiences. Concepts like arithmetic operations and ratios are understood through conceptual metaphors that map these concrete experiences onto abstract mathematical domains. Teaching the origins of mathematics allows students to derive meaning and develop problem-solving skills by experiencing how concepts emerge from real-world contexts over time.
Reflections on understanding in mathematicsLamrabet Driss
The document discusses various perspectives on understanding in mathematics. It focuses on understanding geometric transformations as an example. Understanding a concept involves structural, operational, semiotic, descriptive, functional, and epistemological aspects. The structural aspect involves understanding formal definitions and statements. The operational aspect involves using concepts appropriately. The semiotic aspect involves recognizing different representations of concepts. The descriptive aspect involves understanding properties and relationships. The functional aspect involves applying concepts to solve problems. The epistemological aspect involves making conjectures and having a critical perspective. Understanding requires considering all these interrelated aspects to have a rich comprehension of mathematical concepts.
This document discusses different perspectives on metaphors and challenges in recognizing and representing metaphors computationally. It reviews ongoing research aiming to accomplish these goals. There is no consensus on what constitutes a metaphor. Linguistic metaphors found in examples are distinguished from cognitive metaphors, which are not linguistic phenomena. Metaphors can involve referential substitution or predication. Framing and context are important for interpretation. Metaphors may be inexhaustible or conventionalized into new meanings. Recognizing metaphors computationally is difficult as literal and figurative meanings depend on context and intention.
This document presents a method for measuring the semantic similarity of short texts using both corpus-based and knowledge-based measures of word semantic similarity. It combines word-to-word similarity scores with word specificity measures to determine the overall semantic similarity between two text segments. The method is evaluated on a paraphrase recognition task and is shown to outperform methods based only on simple lexical matching, resulting in up to a 13% reduction in error rate.
Supervised Corpus-based Methods for Word Sense Disambiguationbutest
This chapter discusses supervised learning approaches to word sense disambiguation (WSD). It introduces machine learning concepts for classification and reviews major supervised WSD approaches. It describes five learning algorithms that are experimentally evaluated on the DSO corpus. The challenges of the supervised learning approach to WSD are also discussed.
1. The document discusses the need for a positive account of informal proof in mathematics, as most mathematical proofs are informal. It argues against the view that informal proofs are recipes for formal derivations.
2. The document proposes that logic should be understood more broadly as the general study of inferential actions, as informal proofs often involve actions on mathematical objects beyond propositions. Examples of such actions include diagram manipulation in Euclidean geometry.
3. The document reviews work that may support this broader view of logic in informal proofs, such as studies of reasoning with diagrams in knot theory and using Cayley graphs to prove group theory results.
Construction grammar views grammatical constructions as the basic units of syntax, where a construction is a form-meaning pairing. It denies a strict distinction between lexicon and syntax, instead proposing a continuum. There are different models of how constructions are organized in the grammar, including a full entry model with minimal generalization, a usage-based model based on inductive learning, and models with varying degrees of inheritance. Construction grammar rejects derivation and adheres to no synonymy, viewing related constructions like active and passive as distinct. Various approaches within construction grammar emphasize different aspects, such as form (Berkeley construction grammar), psychological plausibility (Goldbergian construction grammar), or embodiment. The strength of construction grammar is its claim that many grammatical units
The document analyzes how secondary school mathematics textbooks teach the concept of functions between 1953-2010. It categorizes some textbooks using a "hybrid approach" that combines set theory concepts with a focus on graphical representations. This approach presents real-world problems that are then formalized mathematically. However, it is argued that this approach does not fully promote understanding of functions before their formalization and treats problems more as tasks than opportunities for conceptual development. The conceptualization of functions across different representation systems used in textbooks is also examined.

Construction grammar (CxG) is a non-derivational, mono-stratal grammatical model that views language as a repertoire of constructions that integrate form and meaning. Constructions pair syntactic, morphological, and prosodic patterns with lexical semantics, pragmatics, and discourse structure. CxG views the grammar as a network of construction families organized by inheritance and sees syntax and lexicon existing on a continuum rather than as distinct modules. There are different variants of CxG that emphasize formal, functional, semantic, or typological aspects.
A Constructive Mathematics approach for NL formal grammarsFederico Gobbo
This document discusses formalizing natural language grammars through adpositional grammars (AdGrams). AdGrams are based on cognitive linguistics concepts of trajector and landmark. The document proposes that natural language structure can be expressed through a triple involving a governor, dependent, and their relation. It provides examples analyzing phrases and sentences as either dependency-based or government-based structures based on whether the dependent or governor is the trajector. The goal of AdGrams is to formalize natural language grammars in a way that is informed by cognitive linguistics concepts and can be computationally analyzed.
This document discusses the benefits of using comparative analysis when teaching cases in business schools. It argues that case analysis could be supplemented by comparing a few cases using a "compare-and-contrast" method, similar to approaches used in comparative literature. Comparative literature looks at relationships between identity and difference in texts, and how insights can be generated by juxtaposing texts. The document suggests case analysis could similarly benefit from formally comparing and contrasting cases to better understand technical and cultural differences and their influence on interpretation.

The role of theory in research division for postgraduate studiespriyankanema9
This document discusses the role of theory in research. It provides definitions of theory as a model or framework that shapes observation and understanding. Theory condenses and organizes knowledge about the world and explains relationships between variables. The document outlines characteristics of theory such as guiding research, becoming stronger with evidence, and generating new research. It distinguishes theories from hypotheses and discusses evaluating theories. The dynamic relationship between theory and research is also examined, with theory informing research and research testing and revising theory. Different types of theories like deductive and inductive theories are defined. The document concludes by discussing theories relevant to multilingual mathematics education research and theories of second language learning.
The document discusses the distinction between theoretical and practical thinking in mathematics. It presents a model that defines theoretical thinking as focusing on conceptual connections, logical reasoning, and developing consistent theories, while practical thinking focuses on solving particular problems and understanding factual relationships. The author argues that successful mathematics students demonstrate a "practical understanding of theory" by applying theoretical knowledge flexibly to efficiently solve problems. Examples of student work show the importance of both theoretical and practical thinking skills for high achievement in university mathematics.
This document provides a preface for a textbook on mathematical physics. It discusses the interplay between mathematics and physics, with mathematics serving as the language through which physics expresses itself. The preface outlines the level, philosophy, features, organization and topical coverage of the textbook. It is intended for advanced undergraduate and beginning graduate students and aims to present topics with a balance of formalism and application.
Objectification Is A Word That Has Many Negative ConnotationsBeth Johnson
Here is an introduction to social web mining and big data:
Social web mining is the process of extracting useful information and knowledge from social media data. With the rise of big data, social media platforms are generating massive amounts of unstructured data every day in the form of posts, comments, shares, likes, etc. This user-generated data holds valuable insights about people's opinions, interests, behaviors and more.
Big data analytics provides tools and techniques to analyze this large, complex social data at scale. Social web mining applies data mining and machine learning algorithms to big social data to discover patterns and relationships. Areas of focus include sentiment analysis to understand public opinions on brands, products or issues; network analysis to map relationships and influence; and
This document summarizes and discusses several theories of second language acquisition (SLA). It argues that SLA is a complex process that cannot be fully explained by any single theory. While each theory captures aspects of SLA, they need to be considered together to get a broader understanding. The document reviews several mainstream SLA theories, including behaviorism, the universal grammar hypothesis, the comprehension hypothesis, the interaction hypothesis, and the output hypothesis. It concludes that SLA is best understood as a chaotic/complex adaptive system, since learners' development can be influenced by many internal and external factors interacting in complex ways.
This document summarizes a transcript from the PEMT '06 conference discussing challenges with terminology across disciplines and proposes approaches to address ambiguities. It notes how knowledge evolution has led to specialized terminology that may only be understood by experts, hindering cross-disciplinary communication. Defining terms unambiguously is important for knowledge management. The document provides examples of ambiguous terms like homonyms and synonyms and proposes establishing a transparent, inter-disciplinary lexicon using fundamental disciplines like physics and mathematics to prioritize terms. It emphasizes the need to review scientific terminology to remove ambiguity and proposes criteria to clearly define terms.
This document discusses the role and importance of theory and concepts in educational research. It argues that theory helps researchers ask significant questions, approach research rigorously and imaginatively, and shed light on taken-for-granted circumstances. While theory can also close down thinking and marginalize practices, it can empower research by recovering and claiming knowledge. The document provides examples of concepts commonly used in educational research like identity, pedagogy and knowledge, and influential theorists like Habermas, Foucault and Bourdieu. It emphasizes that theory should align with and inform research questions, methodology, data collection and analysis.

Literature Review
Integrated Learning in Social Studies Education
Based on the literature reviewed for this assignment, there seems to be a fairly widely-held consensus (though largely anecdotal (see Research Methodology Issues)) among many education professionals that social studies, when integrated with other subjects, increases one's ability to learn more effectively across a broad range of subject matter. Nuthall (1999), for example, analyzed the learning habits of five students in an integrated science and social studies unit on Antarctica. His study concluded that the integration of these two subjects allowed students to acquire new knowledge in each of the disciplines that may not have been similarly acquired had the courses been taught separately. Educators in other areas of study have conveyed similar anecdotal results concerning their respective areas of study as well.
Matheus' (2000) study on using an integrated content social studies class as a means of developing problem-solving skills also cites the validity of integrated social studies curriculum. The author concludes that the integration of social studies curriculum with other subject matter creates connecting pathways between each which can apply across disciplines and even beyond the classroom.
Theodore Kaltsounis (1990) also concludes that, although.
The passage discusses models of metadiscourse. It defines metadiscourse traditionally as "text about text" but notes this definition is too broad. It explains metadiscourse borrows reflexivity from language's ability to comment on itself through metalanguage. The passage indicates metadiscourse focuses on the metalinguistic function of language within texts.
This document discusses the relationship between second language acquisition (SLA) research and language pedagogy (LP). It notes there have been contradictory views on their relationship, from no relevance to complete relevance. The author aims to tackle this controversial issue and provide suggestions from a practitioner's perspective. The document provides background on the development of SLA research and its relationship to LP over time. It discusses debates around the relevance and application of SLA research to LP, noting varying perspectives from skepticism of application to arguments for a positive relationship. The author concludes that realizing the mutual ties between SLA research and LP is important, and questions what the ultimate aim of SLA science is if not to inform language pedagogy and classroom instruction.
Analysing classroom interactions using critical discourse analysishoragabomilo
This document analyzes classroom interactions in a year 8 mathematics classroom using critical discourse analysis. It summarizes the key points of the classroom discussion, where students took turns explaining graphs they drew to explore the concept of gradient. The analysis uses Fairclough's three-dimensional framework to examine the discourse as text, discursive practice, and social practice. It finds that in this classroom, students were empowered and agency was shared, in contrast to more traditional classrooms where the teacher maintains most of the control. The discourse encouraged generative understanding over simple reproduction of knowledge.
This document discusses critical discourse analysis (CDA) and the relationship between discourse and knowledge. It contains several key points:
1) CDA aims to explicitly relate discourse and knowledge, but both are complex phenomena studied across many disciplines.
2) The relationships between discourse and knowledge have philosophical, linguistic, psychological, sociological, and anthropological dimensions.
3) Several aspects of the discourse-knowledge interface are discussed, including epistemological foundations, cognitive theory, linguistic forms, knowledge management, and the social/cultural dimensions of language.
4) A multidisciplinary approach is needed to fully describe the interface between discourse and knowledge.
Relationship between Creativity and Tolerance of Ambiguity to Understand Metaphorical Polysemy: A Pilot Study
Maha Ounis,
Department of English, Faculty of Letters and Humanities, University of Sfax, Tunisia
This study focuses on lexical ambiguity as polysemous words were proved to hinder meaning understanding. In an attempt to operationalize polysemous words from a cognitive perspective, the researcher deduces that metaphorical polysemy engenders words with basic and peripheral (or metaphorical) senses. Participants were asked to answer Multiple Stimulus Types Ambiguity Tolerance Scale II (MSTAT II). Then, they answered Wallach and Kogan Creativity Test, which revealed a slight positive relationship with MSTAT II. Furthermore, the results show two things. First, there is a positive relationship between creativity and semi-technical vocabulary tests scores. Second, there is a link between creativity level and understanding the prototypical meanings of words. Contrarily, MSTAT II and prototypical meanings tests scores correlation is very weak.

MATD611 Mathematics Education In Perspective.docxstirlingvwriters
The document discusses four views of mathematics:
1) Logicism view - Mathematics is a continuation of logic and can be reduced to logic.
2) Intuitionist view - Mathematics is a product of human imagination and must be mentally constructed.
3) Instrumentalist view - Mathematics is a collection of unrelated rules and facts that serve practical purposes.
4) The document also discusses teachers' views on the nature of mathematics, the benefits of teaching history of mathematics, and ways to implement student-centered learning in mathematics classrooms.
This document is an assignment on research in mathematics education. It discusses the nature of research in mathematics education compared to mathematics. It notes that while mathematics uses proofs, research in mathematics education uses various forms of evidence to build understanding. It outlines the main purposes of research in mathematics education as understanding mathematical thinking and learning as well as improving instruction. It also discusses standards for evaluating theories and models in mathematics education research, including descriptive power, explanatory power, scope, predictive power, rigor, falsifiability, replicability, and using multiple sources of evidence. The document concludes by emphasizing that mathematics education research is still a young field with progress being made to build robust theory and methods.
Collaboratve Conceptual Change : The Case of RecursionDalit Levy
The paper tries to shed some light on the conceptual development of computer-science concepts by discussing recursion as an interdisciplinary idea and by analyzing the class discourse during an introductive learning activity. Throughout the inductive analysis of the discourse, the students’ expressions were interpreted, refined, and formulated as ‘preconceptions’. After a short theoretical and methodological background (in Secs. 2 and 3), we present these pre-conceptions, suggest an organizing model of conceptual change, and discuss certain implications concerning the issue of understanding recursion by high school students and of the collaborative development of such understanding.
The document discusses the relevance of discourse studies in education. It notes that education is predominantly textual, as most learning materials are in the form of texts. Discourse studies can provide insight into textual structures and processes of learning from texts. Analyzing discourse structures used in education and how they influence learning can lead to a better understanding of educational processes.

The document discusses frameworks for understanding the relationship between the worlds of the student, teacher, and researcher in higher education. It describes how these roles are interrelated through shared concepts of knowledge construction, dialogue, and learning. Specifically, it provides three key points:
1) The student, teacher, and researcher roles are defined by their encounters with one another and share conceptual frameworks, despite tensions between these worlds.
2) Important features of the frameworks are their social-constructivist view of knowledge and the dialogic nature of language as critical to knowledge exchange.
3) Principles of academic dialogue that characterize best practices emphasize collaboration, equity, reflection, and integrating teaching, research, and learning to increase knowledge.

HijackLoader Evolution: Interactive Process HollowingDonato Onofri
CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities.
In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.

Social activity method (SAM): A fractal language
for mathematics
Paul Dowling
Received: 24 July 2012 /Revised: 17 November 2012 /Accepted: 12 February 2013 /

Abstract In this paper I shall present and develop my organisational language, social
activity method (SAM), and illustrate some of its applications. I shall introduce a new
scheme for modes of recontextualisation that enables the analysis of the ways in
which one activity – which might be school mathematics or social research or any
empirically observed regularity of practice – recontextualises the practice of another
and I shall also present, deploy, and develop an existing scheme – domains of action –
in an analysis of school mathematics examination papers and in the structuring
of what I refer to as the esoteric domain. This domain is here conceived as a hybrid
domain of, first, linguistic and extralinguistic resources that are unambiguously
mathematical in terms of both expression and content and, second, pedagogic theory –
often tacit – that enables the mathematical gaze onto other practices and so
recontextualises them. A second and more general theme that runs through the paper is
the claim that there is nothing that is beyond semiosis, that there is nothing to which we
have direct access, unmediated by interpretation. This state of affairs has implications for
mathematics education. Specifically, insofar as an individual’s mathematical semiotic
system is under continuous development – the curriculum never being graspable all at
once – understanding – as a stable semiotic moment – of any aspect or object of
mathematics is always localised to the individual and is at best transient, and the
sequencing of such moments may well also be more individualised than consistent in
some correspondence with the sequencing of the curriculum. This being the case, a
concentration on understanding as a goal may well serve to inhibit the pragmatic
acquisition and deployment of mathematical technologies, which should be the principal
aim of mathematics teaching and learning. The paper is primarily concerned with
mathematics education. SAM, however, is a language that is available for recruiting
and deploying in potentially any context as I have attempted to illustrate with some of the
secondary illustrations in the text.

Recontextualisation
Forensics and the myth of reference
There is a marked tendency in social and educational research to promote what I have
called the myth of reference (Dowling 1998), which is to say, to present itself as if it
were about something other than itself, as if the language of the research represents
objects and activities that the research has uncovered, but that, in principle, are
accessible to all of us. Having represented the world, the mechanisms articulating
the representation are pushed into the represented world and represented as causal
structures. I call this forensics (Dowling 2009). The research game proceeds as a
wrestle over which language constitutes the best representation, which structures the
most deserving causes. I want to take a different tack. This paper presents an
organisational language – SAM – that is about itself. This is achieved within a
general approach that I refer to as constructive description (Dowling 1998, 2009)
on which a little more later. Having announced this, I need to address two urgent
issues. First, I do not mean to claim (or even aspire to) solipsism. I must establish an
exteriority, which I shall refer to as the empirical setting (Dowling and Brown 2010).
I will name the setting “knowledge,” for the time being. This minimal detail is
sufficient to give me a bearing on what lies beyond my constructions. The outcome
of my engagement with the setting, however, is not a representation, but a
recontextualisation so that, ultimately, “knowledge” becomes incorporated into my
language.
Second, I must explain the significance of the term “for” in my title, because it
may seem to signal a dualism that I appear to be denying. There is, however, no
denial. Mathematics may be said, here, to stand for my audience; then “for” consti-
tutes my language as a gift, the value of which is to be determined by that audience in
pragmatic terms (and here Rorty (1989) and Schön (1987) and perhaps Carr and
Kemmis (1986) are inspirational): Is it useful? If it is useful, then it might be fetched
into mathematical practice, which move will entail another recontextualisation.
Naturally, I shall attempt to market the language by offering some illustrations of
SAM’s use.
A second and associated tendency in educational research is the totalising of the
represented in conformity with the representation. Here is Basil Bernstein on math-
ematics and other knowledge structures:
It might be useful here to make a distinction within horizontal knowledge struc-
tures, distinguishing those whose languages have an explicit conceptual syntax
capable of ‘relatively’ precise empirical descriptions and/or of generating formal
modeling of empirical relations, from those languages where these powers are
much weaker. The former I will call strong grammars and the latter weak
grammars. It is important to add here that ‘strong’ and ‘weak’ must be understood
as relative within horizontal knowledge structures. From this point of view,
economics, linguistics and parts of psychology would be examples of strong
grammar. Mathematics would also be considered a horizontal knowledge structure
318 P. Dowling
3. as it consists of a set of discrete languages, for particular problems. Thus,
mathematics and logic would be regarded as possessing the strongest grammers
[sic], although these languages, for the most part, do not have empirical referents
nor are they designed to satisfy empirical criteria. Examples of weak grammars
would be sociology, social anthropology, and cultural studies.
(Bernstein 1999; 164)
The two characteristics of mathematics are, first, that it is a horizontal knowledge
structure, that is, it consists of “a series of specialised languages with specialised modes
of interrogation and criteria for the construction and circulation of texts” (Bernstein
1999; 162). This contrasts with a hierarchical knowledge structure that “takes the form
of a coherent, explicit, systematically principled structure, hierarchically organized”
(Bernstein 1996; 171). Second, mathematics has a strong grammar, although it is not
entirely clear what the latter means given that it is defined above in relation to the
precision of empirical descriptions, whilst mathematics itself is denied empirical refer-
ents. I shall return to this later. Meanwhile, here is Raymond Duval distinguishing
between mathematics and “other domains of scientific knowledge,” totalising both:
From an epistemological point of view there is a basic difference between
mathematics and the other domains of scientific knowledge. Mathematical
objects, in contrast to phenomena of astronomy, physics, chemistry, biology,
etc., are never accessible by perception or by instruments (microscopes, tele-
scopes, measurement apparatus). The only way to have access to them and deal
with them is using signs and semiotic representations. That means that we have
here only a single access to the knowledge objects and not a double access,
mainly non-semiotic and secondarily semiotic, as is the case in the other areas.
(Duval 2006; 107)
Further:
Mathematics is the domain within which we find the largest range of semiotic
representation systems, both those common to any kind of thinking such as
natural language and those specific to mathematics such as algebraic and formal
notations. And that emphasizes the crucial problem of mathematics compre-
hension for learners. If for any mathematical object we can use quite different
kinds of semiotic representation, how can learners recognize the same repre-
sented object through semiotic representations that are produced within differ-
ent representation systems?
(Duval 2006; 108)
The second of these extracts illustrates Duval’s (2006) forensic action. First,
mathematics is represented as a domain that mediates its objects through multiple
semiotic systems. This is a structural feature of Duval’s representation that is pushed
into the empirical as a structural feature of mathematical knowledge. Second, this
being the case, aspiring acquirers of mathematical knowledge are potentially disabled
by this multiplicity. Now, adopting my pragmatic principle of evaluation, the forensic
nature of the argument may not matter to the extent that the result proves to be useful
Social activity method (SAM) 319
4. in mathematics education. Forensic action – the pushing of a representation into a
supposedly represented setting – may, however, distract us from the representation
itself. To explain what I mean, I want to return to the first of the Duval extracts in
which, in effect, he distinguishes between two modes of knowledge, one of which –
characterising “other domains of scientific knowledge” – provides access to its
objects either by direct perception or via intermediary technology that does not
function semiotically, that is, is semiotically inert. The other form of knowledge –
mathematics – mediates its objects via (multiple) semiotic representations. I shall
explore the first case through an example from astrophysics as another domain of
scientific knowledge. Here is the abstract of my exemplar paper to provide a sense of
the nature of astrophysical representation (please bear with me!).
Photometric redshifts can be routinely obtained to accuracies of better than 0.1
in Δz/(1 +z). The issue of dust extinction, however, is one that has still not been
well quantified. In this paper the success of two template-fitting photometric
redshift codes (IMPZ and HYPERZ) at reliably returning AV in addition to
redshift is explored. New data on the 2nd Canadian Network for Observational
Cosmology (CNOC2) spectroscopic sample of 0.2<z<0.7 galaxies are
presented. These data allow us to estimate AV values from the observed Balmer
decrements. We also investigate whether the empirical value of γ= 0.44, the
ratio between gas- and star-derived extinction, as determined by Calzetti, is
necessarily the best value for this sample.
When comparing the two codes with the Balmer-derived AV (Balmer [AV]), a
correlation between the photometrically derived AV (Phot [AV]) and the Balmer
[AV] is found. The correlation is improved when the empirical value of γ of
0.44 is allowed to vary. From least-squares fitting, the minimum in the reduced
χ2
distribution is found for γ ~0.25±0.2. For the sample of galaxies here, the
factor of 2 difference in covering factor implied by the Calzetti ratio is found to
be plausible. The CNOC2 galaxies with detected Balmer lines have some
preference for an increased covering-factor difference, which perhaps implies
that they are undergoing more rapid, ‘bursty’ star formation than the galaxies
Calzetti used in her derivation.
(Babbedge et al. 2005; 443)
This may need a little unpicking for the non-specialist reader. Essentially, my
interpretation of the argument in this paper is as follows:
1. Stellar evolutionary history can be inferred from electromagnetic (em) spectral
energy distribution (SED);
2. Galactic dust absorbs and reflects some of the em energy; this is called dust extinction;
3. Physicists need to correct for dust extinction if they are to determine stellar histories;
4. Babbedge et al. compared the results of using two photometric codes with
another method;
5. They found strong correlation between the results of the two photometric codes;
6. They also found quite a good correlation with the third method, when the poor
accuracy of all three methods was taken into consideration;
7. They concluded that the measurement of dust extinction was reliable but not accurate.

5. The data for this research was collected via the Canada-France-Hawaii Telescope –
located on Mauna Kea on Hawaii island – which is an optical/infrared telescope. The
outputs from this instrument are presented in the paper by graphs and tables of
wavelength intensity distributions et cetera and not as photographs of stars, but, in
either case, the output would be meaningless in the absence of the principles of
deployment and reading of the instrument and the astrophysical discourse that produces
both the experiment and the results presented in the paper and, indeed, the form of the
argument presented above. Certainly, the telescope is pointing away from the physicists
and at something constituted as the empirical, but just what this is is entirely consumed
by an articulation of, on the one hand, physics theory, and, on the other, what Latour and
Woolgar (1979) referred to as inscription devices and their principles of deployment and
reading. That is to say, the objects of astrophysics – galaxies, the electromagnetic
spectrum, galactic dust, and so forth – are constituted and not represented by the practice
of astrophysics; real galaxies, electromagnetic radiation, and dust are postulated by a
positivist interpretation of the activity and serve to legitimate astrophysics for those of us
who make our living in other ways: the myth of reference (Dowling 1998) – forensics.
Crucially, the situation in respect of the objects of mathematics as postulated by Duval
(2006) – objects that are accessible only via semiotic representations – is identical.
Identical, that is, except for the currently unfashionable nature of platonic discourse that
would reify them in the way that both everyday and physics discourses reify their objects
(note in particular the recent fuss over the Higgs boson1
). Duval’s explanation of the
particular difficulties experienced by students of mathematics – his forensic push into
the empirical world of mathematics education – founders because at least one of the
specificities of mathematics that he identifies is revealed as of his own construction. The
other specificity – that mathematics, par excellence, deploys a range of semiotic
representation systems – is a poor representation of knowledge (to use his own form
of argument) as the most casual glance at the physics curriculum will affirm.
Discursive saturation and grammatical modes
I have constituted astrophysics, as instanced in Babbedge et al. (2005), as deploying
two forms of “language,” astrophysics theory and inscription devices together with
their principles of operation. I want to refer to these two languages as instances of
internal and external languages, respectively. Bernstein distinguishes between the two
as components of a “language of description” as follows:
Briefly, a language of description is a translation device whereby one language is
transformed into another. We can distinguish between internal and external lan-
guages of description. The internal language of description refers to the syntax
whereby a conceptual language is created. The external language of description
refers to the syntax whereby the internal language can describe something other
than itself.

6. I am going to use the expression organisational language rather than
Bernstein’s “language of description.”2
Let us take the organisational language
to be constituted by the research language – the translating or representing
language – and comprising internal and external languages; this is what I am
going to be talking about below. The empirical setting is, referring to the
Bernstein extract above, the other language – the language that is to be translated
into the research language or, in other words, the language that is to be
represented. Referring back to the astrophysics example, then, we might identify
the language of astrophysics theory as the internal language and the apparatus of
inscription devices and associated principles of operation as the external lan-
guage. At this point I need to make reference to a construct from my own
language, discursive saturation (DS) (see Dowling 1994, 1996, 1998, 2009). I
refer to strategies that tend to make the principles of a practice available
explicitly within language as high discursive saturation (DS+
); low discursive
saturation (DS-
) refers to the opposite situation in which strategies are tacit. Now
the abstract from Babbedge et al. (2005) suggests that both internal and external
languages of astrophysics, as constituted in the paper, are characterised by DS+
strategies. I refer to this kind of an organisational language as a metonymic
apparatus (Dowling 2009). The astrophysics of Babbedge et al., then, stands in
contrast with Bernstein’s own language, which tends to remain in the internal.
This is certainly explicitly developed, but, as I have argued in Dowling (2009),
there is no developed external language – no Bernsteinian telescopes – so that
Bernstein’s concepts are both too easy and too difficult to operationalise; they do
no work in engaging with the empirical. Bernstein’s language is a metaphorical
apparatus.
SAM is really the opposite kind of thing from Bernstein’s language. Its external
language – the operationalised/operationalisable content – is explicitly developed;
approximately 200 categories are summarised in the glossary presented in Sociology
as Method (Dowling 2009) and more have been added since then. I shall present
some of this structure – including some new elements – in this paper. The internal
language, however, is relatively undeveloped and is summarised in the following
sentence: the sociocultural constitutes and is constituted by strategic, autopoietic3
action directed at the formation, maintenance and destabilising of alliances and
oppositions, the visibility of which, in terms of regularity of practice, is emergent
upon the totality of such action and is thereby available for recruitment into subse-
quent action. Key terms here (though all are important) are: strategy, action, alliance
and opposition, and emergence. Essentially, the external language arises and is
developed out of the transaction between this internal language and empirical set-
tings. The internal language is a kind of prejudice or bias – a “guiding thread” as
Marx (1968 edn) famously described his base/superstructure metaphor – but it is the
external language that stands as a legacy of successive engagements. I refer to SAM
as a method and in this it perhaps resonates with classic grounded theory (Glaser and
Strauss 1965, 1967; Glaser 1992; Martin and Gynnild 2011, see also Dowling 2012);

7. classic grounded theory is not a theory, but a method and grounded theory is what
emerges from its deployment.4
At this point, I am in a position to summarise the schema of grammatical modes of
organisational languages in diagrammatic form in Table 1. Three of the categories have
already been mentioned. The fourth – fiction – constitutes a strategy that exhibits DS-
in
respect of both internal and external languages. This mode characterises some
approaches in literary criticism – see, for example, Leavis (1950) – but certainly not
all: The new historicism of Louis Montrose (1989) and other examples of literary theory
would perhaps be better described as deploying metaphorical apparatus.
A crucial point should be made about this schema before I proceed. It will be
apparent that it is organised on the basis of discrete, binary-scaled variables and this is
generally characteristic of the schemas that comprise the external language of SAM.
Essentially, this is a complete space: There are no other possibilities if grammatical
modes are conceptualised in this way. This kind of scheme is often criticised as
oversimplifying its concepts that, surely, should be constituted as continua. A con-
tinuum, however, can be established only where there is a metric and here there is
not.5
The schemes do not unduly reduce complexity, because any given instance – the
astrophysics example, for instance – will generally be revealed as deploying more
than one strategy. It will, though, always be possible to identify single strategies by
setting the level of analysis low enough. The scheme then serves as a language that
can map the practice: where and under what circumstances does it operate as a
method, where as a fiction, for example.6
The lack of this facility is a key failure of
Bernstein’s language that, as I have illustrated above, tends to totalise practices:
Mathematics, according to Bernstein, is a horizontal knowledge structure with a
strong grammar; all of it and in all of its realisations, apparently.7
4
The internal language of classical grounded theory is, of course, widely contested (although not by its
“mentored” exponents – see Martin and Gynnild 2011), but is it all that important?
5
The imagination of a continuum where there is no obvious metric is widespread and clearly itself a
reduction. It is sometimes introduced with perhaps less culpability in pedagogic texts – see, for example,
the reflection on the participant/observer “continuum” in Dowling and Brown (2010) – though it is still
doing violence to the concepts.
6
The accumulation of such codings may enable us to identify a dominant strategy or strategies. Again,
however, this is not going to be straightforward because the enumeration of strategies renders all codings to
be equivalent. This is a problem to the extent, for example, that the particular prominence or situation of a
given instance of, say fiction, may establish it as having far greater semiotic significance than multiple
instances of method. None of this is to argue that counting should be avoided at all costs in qualitative
research, but it must be handled with care and, even so, will always distort.
7
Having just argued against the totalising of disciplines alongside the presentation of examples that may be
taken to do exactly that, a little further explanation is needed. The examples that I have used are from
astrophysics (Babbedge et al.), sociology (Bernstein, Dowling), and literary criticism (Leavis, Montrose). I
am referring to these as instances within disciplines rather than as representatives of disciplines. The
divergence between Bernstein and Dowling, in sociology, and Leavis and Montose, in literary criticism,
makes plain that disciplines are not military institutions, demanding uniformity. Indeed, a closer look at
each of these instances would doubtless identify the presence of other strategies, so that even they are not
pure instances. This having been said, no extended analysis of these examples is offered and their purpose
in this paper is primarily pedagogic. So, I have to admit to a playing on presumed stereotypes that enables
me to assume a ready association of physics with inscription devices and internal theory and a common, if
unfortunate, association of literary criticism with fiction; unfortunate, perhaps, though I think that fiction
(i.e., of my kind) is rather what Leavis was advocating.

8. Domains of action
So how about mathematical organisational language(s)? Michel Foucault described
the discipline as “the only discursive practice to have crossed at one and the same
time the thresholds of positivity, epistemologization, scientificity, and formalization”
(1972; 188), but it is not clear just what Foucault may be looking at (or when) in
claiming this generalisation. In his own totalising description, above, Bernstein de-
scribes mathematics (and logic) as not having empirical referents. This kind of
generalisation is rather characteristic of Bernstein’s (and sometimes Foucault’s)
apparent lack of a sense of need of the empirical; the single example of the mathe-
matician John Forbes Nash, whose work in game theory won him a share of the
Nobel Prize in Economics in 1994, will suffice to correct him. It is nevertheless the
case that a substantial body of mathematical practice can be described as strongly
institutionalised (I+
) mathematics that is specialised in respect of both form of
expression – deploying the technical terminology and formal notation of
mathematics – and content – constituting specifically mathematical objects and
processes. Focusing particularly on school mathematics, I described this region of
mathematical practice as its esoteric domain (Dowling 1995, 1998, 2009). Because it
is the exclusive domain of I+
expression and content, it is only within this domain that
the principles of mathematical practice can be fully elaborated. Nevertheless, not all
of mathematical practice should be described in this way. Considering the level of
institutionalisation (I+
/I-
) of form of expression and content separately yields four
domains of action as shown in Table 2. In the remainder of this paper I want to
illustrate some uses of this scheme and also to develop it.
In Dowling (1998, 2009) I described the public domain as the product of a gaze
cast by the subject of esoteric domain action beyond I+
mathematics,
recontextualising non-mathematical practice – such as shopping – by organising it
in conformity with mathematical principles. Now, as I have presented the situation
here, this formulation is in need of some adjustment, because, insofar as the esoteric

9. domain comprises essentially self-referential I+
expression and content, it should be
described as a metaphoric apparatus, which is to say, it has no external language that
would enable the gaze. I now want to describe the esoteric domain of school
mathematics as an assemblage (see, for example, Turnbull 2000) or perhaps as a
rhizome (Deleuze and Guattari 1987) that articulates esoteric domain mathematics as
I have described it thus far with pedagogic theory that is more or less explicit
(DS+
/DS-
) and that serves to fetch non-mathematical content and expression and
organise it in such a way as to align with mathematical content and expression. Here
is an example taken from the June 2010 Foundation Tier General Certificate of
Secondary Education (GCSE) paper:
A restaurant offers a family discount. The Taylor family have a meal at this
restaurant. Before the discount the meal costs £140. After the discount the cost
is £112. Calculate the percentage discount.
(p. 21, item 22)8
The nature of the recontextualisation is clear: The parameters are organised so that
the cost of the meal before and after the application of the discount is known, whilst
the amount of the discount is unknown – rendering this a rather improbable (though
not, I suppose, impossible) problem in the restaurant – and the amounts of money
involved are arranged so that the answer comes out to a simple figure (20 %). The
example is public domain because both the setting – content – and mode of expres-
sion are non-mathematical. The next item – from the November 2009 Higher Tier
GCSE paper – is coded as descriptive domain because, whilst the setting – content –
concerns the pricing of newspapers and magazines and is non-mathematical, the text
incorporates I+
mathematical expression:
The cost of a newspaper is x pence. The cost of a magazine is £1.25 more than
the newspaper. The cost of three of these magazines is the same as the cost of
eight of these newspapers.
Show clearly that 3x þ 375 ¼ 8x
(p. 4, item 4(a))
Here is another item from the June 2010 Foundation Tier paper:
Jack has a box of 100 coloured discs. The discs are Red, Blue, Green and
Yellow. The table shows some of the probabilities of choosing a colour.

10. Which coloured disc is the most common?
(p. 14, item 15(a))
Essentially, the setting – content – here is I+
mathematics – probability – but it is
expressed using, primarily, non-mathematical signifiers – coloured discs; this is an
expressive domain strategy.9
It appears that probability is commonly presented by
expressive domain strategies. This is consistent in the 2009 and 2010 GCSE papers
and also in the mathematics textbooks that I analysed in some detail some time ago
(see Dowling 1995, 1998). Insofar as school mathematics is generally constructed in
this way, then access to the esoteric domain in this area is being restricted, possibly
explaining why probability is often found to be a difficult topic. Finally, esoteric
domain strategies involve both I+
expression and content, for example (from the
November 2009 Higher Tier paper):
Solve the simultaneous equations 3x À 2y ¼ 9
x þ 4y ¼ 10
(p. 13, item 16)
I am constructing school mathematics, then, as an assemblage of I+
expression and
content, mathematics per se as a metaphoric apparatus – confined to the esoteric
domain – and a pedagogic theory (DS+/-
) as a method. It is the latter that enables the
mathematical gaze by constituting principles of recognition and realisation of non-
mathematical content and expression, so facilitating the construction of the public,
descriptive, and expressive domains. Quite clearly school mathematics could be
construed differently so as, for example, to incorporate the totality of the school
curriculum into a single entity; the establishing of I+
and I-
strategies in terms of the
expression/content distinction is, after all, an analytic decision. It is, however, an
analytic distinction that has proved useful in generating productive ways of looking at
mathematics and, indeed, at other activities. I have already offered one illustration of
this in the description of the pedogising of probability as being largely confined – at
least early on (Dowling 1995, 1998) – to the expressive domain and so denying
access to the esoteric domain of this topic, a topic that is notoriously intractable for
many students. Brantlinger (2011) makes interesting use of this scheme in the
interrogation of critical mathematics. In earlier publications I also demonstrated the
way in which mathematics for “high-ability” and “low-ability” students was oriented
towards the esoteric and public domains, respectively and, further, insofar as the
recognition principles of “ability” are a function of socioeconomic class, then school
mathematics can be interpreted as a device for translating social class into “ability,”
providing a mathematical career only for students of high social class/”ability” (see
also Dowling 1998, Dowling and Burke 2012).
Leaving mathematics for a moment, the expressive domain can also be constituted
as a productive region for autodidactic pedagogic action. Take, for example, the case
of learning to play a video game. We may constitute the assemblage of hardware
electronics and architecture, game structure and software as the game’s esoteric
domain. For the most part and for most players there is no direct access to this
9
Of course, the term “probability” appears in the text and this is an I+
mathematical term. Strictly speaking,
we should say that this item combines expressive domain and esoteric domain strategies, though the
incidence of the latter is minimal.

11. domain. Instead, the player has access to a keyboard or console and a graphic user
interface (GUI). There are, of course, many ways to engage with a game, some of which
might be described as more destructive than pedagogic. One approach, however, is to
attempt to construct the principles of the esoteric domain in the language of the console
and GUI, which is to say, in the expressive domain. Indeed, the walkthrough sites that
are available for many of these games are formulated in expressive domain text.10
To go
further, this is precisely what is attempted in a great deal of research activity that I refer to
as forensics. Essentially, the social researcher is generally constructing an expressive
domain language in an attempt to represent the esoteric domain of their object setting. In
the more general language of social research, the researcher is deploying or constructing
an etic language contrasting with the emic language of the setting itself. Under such
circumstances, the expressive domain, etic language constitutes the external language of
their research, whilst the general principles or approach and so forth constitute their own
esoteric domain and internal language. A switch will have been noticed here. The etic
language is indeed constituted in an expressive domain from the perspective of the
activity of the empirical setting in and of itself – but is now the descriptive domain of the
activity of the social researcher and the empirical and research activities each constitute
the public domain of the other. The two activities – the setting activity and the social
research activity – confront each other as is illustrated in Fig. 1.
The configuration of the two activities in Fig. 1 presents the etic language of the
setting’s expressive domain and the research descriptive domain as a representation of
the setting activity itself, so that the research public domain is constituted as the same
thing as the setting esoteric domain. The research, in this configuration, is attempting
to discover how the setting really works as if a reality unmediated by semiosis was
available to the researcher.11
This is an illustration of what I have referred to above as
forensics. By contrast, my constructive description approach incorporates the objects
of a language entirely within itself so that the configuration is more appropriately
presented as in Fig. 2.12
Taking anthropology as presented by Clifford Geertz (1988,
1977 (2000 edn)) as an example, the research may start out as the kind of autodidac-
tics that I described in respect of the video game, which is to say, the anthropologists’
attempts to apprentice themselves into the setting; traditionally, this is likely to
involve, amongst other things, learning the local language. The initial phase, then
might be described as the anthropologist attempting to establish an expressive domain
for the setting by “being there” in the field. Ultimately, however, the anthropologist
must present their work to the academy, as Geertz puts it:
In itself, Being There is a postcard experience (‘I've been to Katmandu – have
you?’). It is Being Here, a scholar among scholars, that gets your anthropology
read … published, reviews, cited, taught.
(Geertz 1988; 130; ellipsis in original)
10
See, for example, the walkthroughs on Stella’s Tomb Raider Site at http://tombraiders.net/.
11
Or, alternatively, as if alternative semiotic mediations were somehow comparable or mutually
compensatable so that their respective specificities might be taken out of the equation in a kind of
triangulation process.
12
These and other configurations of the domains of action scheme arose in discussion with Soh-young
Chung (2011), Russell Dudley-Smith and Jeremy Burke. Dudley-Smith and Burke are now completing
their doctoral theses at the Institute of Education, University of London.
Social activity method (SAM) 327
12. It is the social and cultural capital of anthropology that constitutes its esoteric
domain and that constitutes its interpretations as substantive recontextualisations, and
a similar argument explains why the school mathematics classroom is not the place to
learn how to do your shopping.
Modes of recontextualisation
I have, thus far in this paper, said very little about the nature of recontextualisation
other than to claim that it involves a transformation of some kind. I want to
make another short digression to introduce another SAM scheme that lays out
modes of recontextualisation in terms of discursive saturation. This is shown in
Table 3.
Pierre Bourdieu (1977) provides an excellent illustration – again from anthro-
pology – of what can happen when DS+
strategies (I am using my language, not
Bourdieu’s) are deployed on DS-
practice. Bourdieu critiques the analysis of gift
exchange in a non-industrial society by structuralist anthropology.13
As Bourdieu
argues, the anthropologist may write the society’s rules, but the real power plays
are always going to go on in the interstices. The presentation of a gift, for
example, may require that another gift be made in exchange, but this leaves open
the precise nature of the gift (it cannot be the same gift simply given back) and the
13
Bourdieu has in his sights Claude Lévi-Strass, here, though he does a fair amount of recontextualising of
the latter’s work.

13. period of time that may elapse before the exchange is made. Indeed, the extending
of the period may raise a doubt as to whether the exchange gift will ever be
forthcoming. In respect of the anthropology of myth, he warns:
The science of myth is entitled to describe the syntax of myth, but only so long
as it is not forgotten that, when it ceases to be seen as a convenient translation,
this language destroys the truth that it makes accessible. One can say that
gymnastics is geometry so long as this is not taken to mean that the gymnast
is a geometer.
(Bourdieu 1990; 93)
Indeed no: Euclid on the beam sounds excruciating!

14. The “science of myth” would seem to involve the deployment of rationalising
recontextualisation and it seems that school mathematics often recontextualises
domestic and other activities in this way (see the examples in Dowling 1998,
2009). The recontextualising of the restaurant bill introduced earlier also involves
rationalising because the numerical elements of the setting are first fetishized and
then moved around so as to insert the unknown in a place that is determined by
the requirements of the assessment. What I am doing in this paper is deploying
DS+
strategies in the recontextualising of activities – mathematics, anthropology –
that themselves involve substantial DS+
strategies and, to this extent, I am re-
principling. My recontextualisation of the playing of video games, however, is
more like rationalising. Insofar as the setting in Figs. 1 and 2 is predominantly
characterised by DS-
strategies, then the regard of the social scientist by the setting
can be described as de-principling. Indeed, this is also the impact of the
recontextualising of educational research in official documents, which generally
quote selectively, so losing the principled discourse that will have generated the
extracts. Unfortunately, academic authors sometimes have a tendency to do the
same violence to other research that they cite. Finally, the category, improvising,
characterises what Lévi-Strauss (1972) referred to as “bricolage” – recruiting what
is at hand in a semiotic or material construction or production – also, perhaps,
some aspects of improvisation in jazz. To what extent might we construe DS-
pedagogic theory as constituting an improvising gaze in the recognition principles of
its fetch strategies, the mathematical realisation principles effecting rationalising or re-
principling recontextualisation?
In one way or another, when one activity casts its gaze on another, the outcome
will always involve recontextualisation. This, of course, raises serious difficulties for
any notion of functional or transferrable skills, yet the functionality of mathematics
education is generally high on the list of priorities for the school curriculum. The
Australian Curriculum Assessment and Reporting Authority (ACARA), for example,
stresses that the mathematics curriculum should
… educate students to be active, thinking citizens, interpreting the world
mathematically, and using mathematics to help form their predictions and de-
cisions about personal and financial priorities.
(ACARA quoted by Sullivan 2011)
The imposition of mathematical principles on decision making is always
rationalising or (one suspects less frequently) re-principling recontextualisation:
The world is frequently rationalised mathematically or by other DS+
practices,
but, in practice, decisions seem often to be apparently successfully formulated
on the basis of what is better described as improvisation as, for example, many
of the approaches reported in Lave et al. (1984) illustrate. Even the natural
sciences are not always as rational as we might think (see, famously, Latour
and Woolgar 1979, and also Knorr Cetina 1999, Collins and Pinch 1998). What
I have elsewhere (Dowling 2007, 2009) referred to as mathematicoscience is
nevertheless hegemonic in educational policy discourse. Here is the opening
statement of the UK National Curriculum for Secondary Mathematics:
330 P. Dowling
15. Mathematical thinking is important for all members of a modern society as a
habit of mind for its use in the workplace, business and finance, and for
personal decision-making. Mathematics is fundamental to national prosperity
in providing tools for understanding science, engineering, technology and
economics. It is essential in public decision-making and for participation in
the knowledge economy. Mathematics equips pupils with uniquely powerful
ways to describe, analyse and change the world.14
In this statement, mathematics is presented as being entirely for something other than
itself and this is presented in the form of the myth of participation (Dowling 1998),
which is to say, mathematics is a necessary facility for participation in the non-
mathematical activities cited. Now, my analysis of recontextualisation and the examples
given here and elsewhere (in particular in Dowling 1998, 2007, and Dowling and Burke
2012) are sufficient to call into serious question the viability of the this proposition and,
indeed, to reveal the mythical nature of the myth of participation. Suspending this
scepticism, however, it is instructive to deploy the domains of practice scheme in an
analysis of GCSE mathematics papers in order to assess the extent to which they do
indeed prioritise practical mathematics – mathematics for something other than itself. I
used the Foundation- and Higher-Tier papers from November and June 2009 and June
2010 that were available at the time on the AQA site15
and analysed the items in terms of
the four domains of action. As I have indicated above, the setting for esoteric and
expressive domains is I+
mathematical content, differing in respect of the mode of
expression, and the setting for the public and descriptive domains is I-
content (non-
mathematical), again differing in that the descriptive domain incorporates I+
expression,
whilst the public domain does not. In coding, I used the item – differentiated by question
number – as the unit of analysis.16
There were two papers for each tier for each sitting,
giving six Foundation papers and six Higher papers; the results in Table 4 are aggregated
for the two tiers, there being no substantial differences between sittings.
As I have indicated, the esoteric and expressive domains both have esoteric domain
settings and so signify the esoteric domain and, similarly, the descriptive and public
domains signify the public domain. Focusing, then, on the esoteric/expressive and
descriptive/public totals (in bold in the table) there are approximately twice as many
esoteric domain settings in these papers as there are public domain settings – a little less
on the Foundation Tier, a little more on the Higher Tier. When combined with the more
or less transformative impact of recontextualisation on public domain settings – illus-
trated here only via the restaurant item, but consistent throughout these items – it seems
clear that there is a substantial mismatch between the summative assessment of the

could validly be coded in the same way.

16. National Curriculum as represented in these papers and the stated aims of the curricu-
lum: As central as practical mathematics may be in the stated aims of the curriculum, it is
clearly rather sidelined in these assessment instruments.
Mathematics and the esoteric domain
Practical mathematics is not all there is to the school curriculum. Sullivan (2011),
amongst many others, asserts that both “practical” and “specialised” mathematics
should be present, though with the former dominating. In my terms, specialised math-
ematical knowledge17
is constituted in the esoteric domain and finally in this paper I
want to put some detail onto this domain. Duval (2006), as has already been mentioned,
constitutes mathematics in terms of a “range of semiotic representation systems” (p.
108) and the representation to which he is referring is of mathematical objects. This
keeps us within the esoteric domain and is perhaps consistent with Bernstein’s charac-
terisation of mathematics as a “horizontal knowledge structure.” It is clearly the case that
we can topicalise mathematics (algebra, trigonometry, probability, set theory, and so
forth) and we can use what Gunther Kress (2003) and others refer to as different “modes
of representation” in mathematical text; I have, of course, already rejected the term
“representation” for what I can now refer to as esoteric domain or public domain objects.
I do not find it helpful to describe mathematics in either of these ways. Rather, I want to
describe the mathematical esoteric domain of school mathematics as itself consisting of
an assemblage of strategies that includes: i) discursive definitions, principles, theorems,
and so forth; ii) visual exemplars, most obviously in the area of geometry; iii) formal
nomenclatures (the decimal representation of number, for example) and heuristics; and
iv) instrumentation (calculators, computers, geometric instruments, and so forth). Now
this empirically based list can be reconceptualised as a complex apparatus that exhibits
variation in semiotic mode – discursive (available within language)/non-discursive (not
available within language) – and action – interpretive/procedural. This gives rise to the
schema in Table 5.
17
I announced at the head of this paper that I would take “knowledge” as my empirical setting. This is
something of a pragmatic (or perhaps pedagogic) recontextualisation of my own position as I generally
reject the fetishizing of knowledge (or of any “body” of knowledge) as an object that is available for
analysis, though texts associated with that which is often fetishized – mathematics textbooks with
mathematical knowledge, for example – are clearly available as empirical objects. I have addressed this
issue in Dowling 1998 and 2009 (c. 8) and in my critique of Bernstein in Dowling (2009 c. 4), so I will not
pursue it here, but will retain the pragmatic recontextualisation as serving my present purpose.

17. Now, quite clearly, the categories constituted in Table 5 refer to general/
generalisable aspects of the esoteric domain; a template would be of little use if it
constituted a unique instance. These general modes are then repeated as local in-
stances, giving rise to a three-dimensional schema, represented in Table 6. I’ll take a
GCSE item, shown in Fig. 3, to illustrate the scheme. The statements at the head of
the item and the reference to the “angle, marked x, on the diagram” are instances of
localised theorems, which is to say, enunciations. The diagram itself is a graph – a
local, non-discursive, interpretive strategy. The rest of the text consists of instructions
that pertain to assessment and so we might say that this relates to “pedagogic theory.”
The statement “Not drawn accurately” is clearly important in disabling the deploy-
ment of an operational matrix – a protractor – in solving the item via an operation
(measuring the angle on the diagram).
Denied the operational mode, we need to consider what the esoteric domain has to
offer that might be of assistance to us. Essentially, we are looking for general
interpretative or procedural strategies. One approach is to look for templates that
resonate with the diagram in the task and we might refer to this as a procedure or,
with direct reference to the problem graph, as a protocol. Three resonant templates
are shown in Figs. 4, 5, and 6. The titles of each figure include reference to a theorem.
The advantage of the template format, however, is that we can potentially recognise
the template in the problem graph. I have made this easier for those who are at some
distance from their study of school geometry by constructing the templates by
selecting from my digital drawing (in Adobe Illustrator) of the problem graph; this
strategy is, of course, the opposite way around from the approach that a GCSE
candidate would take in solving the problem. It should be quite easy to visualise
the three templates in the graph, so we can conclude that: angle ACD = 40° (from
Fig. 4); angle DAE = 40° (from Fig. 5); so angle CAE = 32° + 40° = 72°; and, finally,
angle x = 180° – (40 + 72)° = 68° (from Fig. 6). These statements are all enunciations
or localised theorems.

18. There are, of course, alternative esoteric domain strategies that might be deployed
in solving this problem. These include reliance on theorems without visualising the
templates. Also, alternative templates might be selected, including, for example, the
one in Fig. 7, which might be deployed in proving or sidestepping the theorems
corresponding to Figs. 2 and 5 or validating the templates, should these

19. theorems/templates not come clearly to mind. All of these templates articulate more
theorems than are likely to be required in any given situation. Figure 7, for example,
connotes (for me; doubtless, I’ve missed some) the following theorems:
1. A circle is the set of points that are equidistant from a fixed point that is its centre;
2. There are two tangents to a circle from any point outside the circle;
3. These tangents are of equal length;
4. The tangents are perpendicular to the radius of the circle at the point at which
they touch the circle;
5. The two tangents to a circle from a point outside of the circle, the line joining this
point with the centre of the circle, and the radii of the circle at the points at which
the tangents touch the circle form two congruent, right-angled triangles;
and also the following operational matrix:
6. Circles and line segments may be constructed by straight edge and compasses (or
using draw software on a computer).
So what is the point of this expansion of language relating to the esoteric domain of
school mathematics; what is its use-value? Earlier, I cited Duval’s (2006) construction of

20. mathematical knowledge as comprising mathematical objects that are represented
or mediated by a range of different semiotic systems. The object-oriented
approach requires the learner to acquire the objects through engagement with
their representations in the various systems and this acquisition might be referred
to as understanding; Duval identifies some of the difficulties that this entails for
the learner. SAM’s approach, by contrast, denies the value of positing objects
that are outside of semiosis. Rather than attempt the transmission of such
mythical entities, SAM emphasises the assemblage of esoteric domain strategies
that are available for recruitment in mathematical activity. This bears some
similarity with Polya’s (1946) listing of heuristics, which, in my scheme, are
classified as procedures. It would, of course, be possible to articulate these
procedures and, indeed, the theorems, templates, and operational matrices into
some kind of more or less coherent discourse, although this would involve the
rationalising of templates and operational matrices. Even if this were to be
achieved, however, the acquisition of the discourse would have to be achieved in
a single move, rather like Foucault’s (1972) all-in-one-go vision of formalised
mathematics. Since this is not possible (in the high school, anyway), understand-
ing – the meanings that can be provided only within the system as a whole –
must be perpetually deferred. We know, in fact, that this is the case: How is it
that elementary school students can possibly be said to “understand” the natural
numbers without a grasp of the Peano axioms (probably unfamiliar even to their
teachers)? What the scheme in Table 6 offers is the basis for a curriculum of
strategic, mathematical resources. In the presentation of such a curriculum, un-
derstandings will come and will go and will change with the partial totalities that
are acquired along the way and will always of necessity be localised to the
individual at a particular point in their mathematical education. Many of these
understandings will be DS-
.18
This may be a shock to those who, like Foucault,
see mathematics as necessarily already fully formalised, but perhaps this is a
necessary shock. SAM’s approach also, incidentally, strikes at the heart of
Bernstein’s totalising.

A necessity that is illustrated by Livingston (1986) in both school (in his introduction) and in advanced
mathematics.

21. Conclusion
In this paper I have, first, offered an alternative to what I am referring to as forensics.
The latter presents its objects as lying, somehow, beyond its own artifice, beyond
semiosis. In astrophysics, the introduction of forensics – we are finding more and
more about the universe, which is real and which was around before us and will be
around after we’re gone – may settle those who live in the world of quotidian
commonsense and perhaps ease the way for funding applications for very big science,
but it won’t necessarily have much of an impact on the day-to-day working of jobbing
astrophysicists. In school mathematics, by contrast, forensics seduces, but then
confuses and ultimately betrays with the promise of mythical objects to be acquired
but, like the carrot dangling from the donkey’s stick or like the greyhound’s hare,
must always be just out of reach – Tantalus in the classroom. Constructionism, in one
form or another, is not new, of course; indeed it’s exactly as old as its positivist other,
the two dancing their perpetual tango, penetrating each other’s spaces, but never
touching except, tellingly, by holding hands. The dance is, of course, infertile. So
I will rely on pragmatic principles to determine the value of the approach that I
present – the organisational language, SAM.
I have presented a number of SAM constructs in this paper. The grammatical
modes scheme distinguishes between strategies that exhibit high and low discursive
saturation in respect of the internal and external languages of an activity. This
scheme, together with the domains of action scheme, enables me to describe school
mathematics as an assemblage comprising a self-referential, mathematical, esoteric
domain as a metaphoric apparatus, and pedagogic theory that may vary in terms of
DS+/-
and that facilitates the gaze that constitutes the other domains of action. This
scheme together with the modes of recontextualisation scheme organises the
fundamental action of recontextualisation that is the inevitable outcome when one
activity regards another, the positivity of an activity being the visible regularity of
social relations and cultural practices – in terms of alliances and oppositions – that is
emergent upon the totality of strategic, autopoietic action that constitutes the
sociocultural and that SAM endeavours to describe. Quite apart from its other
virtues, constructing the world in this way reveals and describes the mendacious
nature of any attempt to totalise or essentialise activity or knowledge such as
mathematics.
I have attempted to illustrate the pragmatic value of SAM by illustrating the way
in which we might productively think about autodidactic pedagogy and about the
action of research activity (for example, in anthropology) as initially autodidactic
and subsequently constituting its own gaze. This formulation may be of value in
thinking about and constructing curricula in research activities. The modes of
recontextualisation scheme provides some indication of the specific impact of the
recontextualisating action of DS+
and DS-
strategies deployed on DS+
and DS-
practice and this, in particular, describes the rationalising action of formalisation on
non-discursive mathematical templates and operational matrices. The deployment of
the domains of action scheme reveals as ideological the UK National Curriculum
claim that mathematics is primarily about something other than itself by revealing
(through an analysis of GCSE papers) both that summative assessment at 16+ is
overwhelmingly concerned with esoteric domain settings and that even where public

22. domain settings are introduced, the effect of recontextualisation brings these settings
into mathematics rather than, for example, taking mathematics out into the world. The
latter effect would require a strategy operating in the opposite direction: not a push
from mathematics, but a fetch from the supermarket. I have also given further
consideration to the nature of the esoteric domain as an assemblage of strategic
resources (in Table 6), arguing that organising the curriculum on the basis of this
assemblage might overcome some of the problems associated with the forensic
approach.
I earlier explained my use of the word “for” in my title. The term left unexplained
is “fractal.” It is there because the method that I am presenting is characterised as
independent of the level of analysis at which it is deployed. I have hinted at this in my
initial explanation of the use of the SAM schemes: You need to reduce the level of
analysis sufficiently in order to identify a unique mode, shall we say, metaphoric
apparatus, metonymic apparatus, method, or fiction. Moving back up the levels of
analysis will reveal any practice as hybrid, but the same language can be used
consistently. Indeed, SAM is also capable of describing its own actions as I have
also illustrated. For example, it operates, essentially, as a method. Its internal lan-
guage – or prejudice – is constituted as a single sentence concerning strategy, action,
alliance and opposition, and emergence – its external language – or dynamic legacy –
comprises the SAM schemes, some of which are presented (and one of which is
developed) in this paper. Primarily, SAM’s analytic action is DS+
, so its mode of
recontextualising tends to be rationalising or re-principling. The diagrams in Tables 1
and 2, Figs. 1 and 2, Table 3, Tables 5 and 6 are graphic renderings of what can quite
easily and unambiguously be rendered discursively; they are theorems rather than
templates. Nevertheless, there must remain substantial DS-
content. I cannot, by
definition, quite get at any of it, but I can point to, for example, the necessary
uncertainty that is involved in the coding generating Table 4 and the semiotic haze
that must obscure all definitions of terms.
So here is a fractal language for mathematics – SAM. Most crucially, how-
ever, its rationalising, re-principling, de-principling, and improvising actions of
recontextualisation must disable the social relations that characterise – albeit on
an emergent basis – the alliances that constitute its object as their own. Once
discourse reaches its limits, other modes must take over.
