The document discusses research into how numerical concepts and representations develop. It proposes that new concepts are formed through extracting operations from existing concepts, coordinating those operations, and applying and evaluating them through a process of trial and error. An exploratory study found that participants used known operations like counting and arithmetic to develop a system of representations for a fictional base-4 number system. The document concludes that conceptual understanding is grounded through explicitly constructing new operations from older ones.

Different Modelling Purposes - an 'anit-theoretical' approachBruce Edmonds
This document summarizes Bruce Edmonds' presentation on different purposes of modeling. It discusses how models can be used for prediction, explanation, theoretical exploration, and analogy, but each model must be justified for its specific purpose. It argues against vague notions of "theory" and advocates for developing more general models through a staged process of building on empirical models in gentler steps of abstraction, rather than through large leaps. The goal is to justify models and their relationships through empirical work before claiming general theories.

This document discusses lean design concepts and lean experimentation. Some key points:
1) Lean design focuses on continuous learning through short, rapid experimentation cycles rather than long development processes. The goal is to validate learning as quickly as possible.
2) Experiments should be planned by starting with the most important hypotheses and determining what minimal tests could validate or invalidate each one. The goal is to learn quickly and cheaply.
3) Human-centered design is incorporated into the lean process by running it as a series of non-linear experiments rather than a rigid, dogmatic process. All activities, including prototyping, are considered experiments aimed at learning.
4) Separating problem and solution hypotheses allows
The document summarizes the key ideas from the book "Where Mathematics Comes From" by George Lakoff and Rafael Núñez. The authors argue that mathematics is not a purely abstract, logical system but is grounded in human cognition and experience. They claim that mathematical concepts are built up over time through image schemas, metaphors, and conceptual blends that originate from basic embodied experiences like containment and motion. According to Lakoff and Núñez, abstract mathematical ideas are understood via more concrete embodied concepts, and mathematical inferences are inherited from the spatial logics of these source domains through conceptual metaphor.
This document discusses Imre Lakatos' view of mathematical discovery as involving proofs and refutations rather than purely deductive proofs. It summarizes Lakatos' analysis of Euler's formula for polyhedra, where counterexamples led to improvements in the conjecture and proof through methods like monster-barring, exception-barring, and lemma-incorporation. Lakatos saw this process as more reflective of human mathematical reasoning compared to the formalist view of deductive proofs alone determining validity. The document outlines Lakatos' view that science involves a similar logic of conjectures and refutations.

The document outlines a study on how people understand positional number systems. It discusses:
1) Using qualitative interviews and an online study to present subjects with "problems" in made-up number systems to see how they make sense of them.
2) Early results showing subjects extracting known operations like repetition and enlarging sequences to continue patterns. They also coordinate operations sequentially to test solutions.
3) The proposed quantitative study would measure subjects' ability to extract regularities, coordinate operations to solve problems, and mentally enact the system through training, consolidation, and testing phases. This quantifies the cognitive mechanisms involved in learning number systems.
The document discusses different ways of representing numbers, from the traditional Hindu-Arabic numeral system to more abstract set-theoretic definitions. It also describes experiments conducted to study how people learn and make sense of non-standard base notation systems like a quaternary (base-4) numbering system. The qualitative studies found people struggled with issues like missing symbols, order of variation in multi-digit sequences, and interpreting the value of the symbol "A". The quantitative study aimed to corroborate these findings and investigate specific problems people encountered. Preliminary results found performance was generally good, but that people commonly struggled interpreting the symbol "A" and its value or position in the numbering system.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

BACKGROUND / RESEARCH QUESTION
General Questions: What are concepts?
How do they come about?
We suppose that:
→ concepts derive from other concepts
→ concept formation uses former (pre-)concepts as “raw material“
→ To answer both questions we have to look at the concepts' grounding,
→ more specifically: we have to answer the epistemological question of how
concepts are grounded in experience.

BACKGROUND / RESEARCH QUESTION
Where does this raw material come from?
"If we do not want to believe that ideas are innate or God-given, but the result of
subjective thinkers' conceptual activity, we have to devise a model of how
elementary mathematical ideas could be constructed - and such a model will be
plausible only if the raw material it uses is itself not mathematical."

BACKGROUND / RESEARCH QUESTION
We are interested in a general mechanism that allows for this construction of
new concepts.
→ therefore the choice of raw material is not crucial, and should be
interchangeable (although it is not arbitrary)
Candidates for this mechanism:
→ Fauconnier's & Turner's Conceptual Blending
→ Piaget's Reflective Abstraction
→…?
So far, we concentrated on Piaget, as he was one of the few who tried to capture
the whole of cognitive development with his model. However, it still lacks detail.

WHY NUMBERS?
- the development starts early, lasts long, results in complex and abstract concept
- numbers are used in a broad variety of contexts, thus providing a lot of material
- numbers are clearly definable and less fuzzy than many other abstract
philosophical concepts

METHODS
Accumulation of several approaches:
Using research from Developmental psychology / Maths Education:
- Looking at how abilities develop may give insight in how they work
- work from e.g. J. Piaget, K. Mix, I. Schwank
Theoretical psychological and philosophical analysis:
- What has to be possible, how can't it be under any circumstances
- e.g. One cannot "store" infinitely many representations of individual
numbers, but one can generate arbitrarily many numbers
- Systematicity: One can combine numbers and operate with them
(cf. Fodor/Pylyshyn)
Problem-solving tasks / Interviews with students:
- observing people solving problems and coming up with solutions
- esp. the structure of their argumentation in correspondence with their
performance

EXPLORATORY STUDY
Setup:
- subjects: a-level students
- 1 interviewer, 1 interviewee, video recording
- interviewer poses problems, subject should solve it
- subject was frequently asked to explain his answers ("Why?")
Tasks:
- base 4 number system, symbols: A,B,C,D A
- participants were not told that it is a number system B
- first task: "What comes next?" (and why)
- then simple arithmetic tasks (+,-,*) in the system C
(also with different symbols and without knowing the rule) D
BA
→ in more general terms:
all of the different small tasks were about BB
deriving general rules from given examples

OBSERVATIONS
Extraction: Many known operations “pop up” (are being extracted) and are used
while subjects try to find a „good“ continuation; e.g.:
- lexical order
- repetition (in cycles of 4)
- enlarging string ( e.g. BA → BAA)
- implicit counting (automatic, without explicit understanding)
- explicit counting (subject already knows the system)
(- usage of known tools, e.g. counting with fingers)
Coordination: Operations are being ordered sequentially and hierarchically, e.g.:
- increasing digits. A then B then C then D
- turntaking, e.g. which switches between increasing digits and enlarging the
sequence
- after one operation has taken place, the next one can apply

OBSERVATIONS
Application & Evaluation of ones ideas. “Running” the coordinated operation and
checking whether it works or „makes sense“; via some kind of judgement about e.g.:
- interviewers reaction
- recognition value
- homogeneity / systematicity of the invented system
- e.g. is generalisation possible? Can I repeat that type of operation?
- “Occam's Razor”
→ A dynamic process of testing, observing, and reordering.
→ Very finegrained equilibration of operations (many details to be studied!) (cf.
Dubinsky, Piaget).

WRAPPING IT UP
cycle of abstraction (“construction & trial & error & correction”)
- extracting of operations (one „sees“ patterns)
- coordination of these operations (hierarchical and sequential order)
- through ongoing application of the operations
- and checking for problems
→ results in a system of operations, that realises a successor function.
but understanding a domain is also
- a smorgasbord of tricks. Subjects develop “shortcuts”, e.g.
knowing that A # C → C and A is like zero, BA # C → BC comes easily
- having implicit understanding. One does not have to know how the number
system works to correctly apply it. But we believe that implicit understanding
comes through explicit construction and only then is becoming automatised.

CONCLUSIONS
→ Grounding is achieved through developing new operations from older ones
through explicit construction.
→ A multitude of established, transparent operations serves as material for the
formation of new ones.
→ A concept consists in operations of what can be done with it (or: of what
it can do). A number, thus, is not an individual, but a system of operations that can
be applied to anything that is recognized as such (e.g. our ABCD-system).
As a consequence we think that research on concepts and representations has to
focus on processes, which embody regularities.
→ For maths education this means that research on ordinality is more
promising than on cardinality (focussing on individual numbers without their
relation to others, cf. Brainerd).

Editor's Notes
(although which kind of raw material is necessary for the development of a specific concept is of course not arbitrary, and finding these is one of the tasks of developmental psychology)
extraction conscious /unconscious coordination hierarchical and sequence checking with interviewer, sequence, intuition component operations come and go
further qualitative studies in a hermeneutic cycle sharpening ideas based on the studies, yielding new questions for further experiments We believe that qualitative investigation does a great job in structuring questions, insights and so on. But are there also possibilities to quantify the claims we derive from qualitative studies?
