Towards Automated Classification of Discussion Transcripts: A Cognitive Prese...Vitomir Kovanovic
LAK'16 Conference paper presentation:
abstract:
In this paper, we present the results of an exploratory study that examined the problem of automating content analysis of student online discussion transcripts. We looked at the problem of coding discussion transcripts for the levels of cognitive presence, one of the three main constructs in the Community of Inquiry (CoI) model of distance education. Using Coh-Metrix and LIWC features, together with a set of custom features developed to capture discussion context, we developed a random forest classification system that achieved 70.3% classification accuracy and 0.63 Cohen’s kappa, which is significantly higher than values reported in the previous studies. Besides improvement in classification accuracy, the developed system is also less sensitive to overfitting as it uses only 205 classification features, which is around 100 times less features
than in similar systems based on bag-of-words features. We also provide an overview of the classification features most indicative of the different phases of cognitive presence that gives an additional insights into the nature of cognitive presence learning cycle. Overall, our results show great potential of the proposed approach, with an added benefit of providing further characterization of the cognitive presence coding scheme.

LAK'17 Conference paper presentation:
Abstract:
In 2011, the phenomenon of MOOCs had swept the world of education and put online education in the focus of the public discourse around the world. Although researchers were excited with the vast amounts of MOOC data being collected, the benefits of this data did not stand to the expectations due to several challenges. The analyses of MOOC data are very time-consuming and labor-intensive, and require a highly advanced set of technical skills, often not available to the education researchers. Because of this MOOC data analyses are rarely done before the courses end, limiting the potential of data to impact the student learning outcomes and experience.
In this paper we introduce MOOCito (MOOC intervention tool), a user-friendly software platform for the analysis of MOOC data, that focuses on conducting data-informed instructional interventions and course experimentations. We cover important design principles behind MOOCito and provide an overview of the trends in MOOC research leading to its development. Although a work-in-progress, in this paper, we outline the prototype of MOOCito and the results of a user evaluation study that focused on system’s perceived usability and ease-of-use. The results of the study are discussed, as well as their practical implications.

An analysis of Teachers’ comments about the advantages and issues of improving the use of digital textbooks in Pilot Schools
The purpose of this research is to identify the advantages and issues of improving the use of digital textbooks in schools. For this objective, an online questionnaire was conducted to 134 representative teachers (Director or Head Teacher) of digital textbook pilot schools (elementary and middle schools) in South Korea during October 2015, and 119 teachers responded. The questionnaire contained 5 open-ended questions about the advantages and issues of improving the digital textbooks, classes using digital textbooks and managing the digital textbook pilot school. Results of the content analysis of the comments were categorized into 4 topics (development of students, digital textbook’s contents, digital textbook’s function, change of instruction). Each of the 4 topics included comments involving advantages and improvements.
Though there were comments about digital textbooks’ side effects such as distractibility and eyestrain to students, positive feedback regarding the implement of students’ concentration, interest and self-directed learning attitudes outweighed the negative comments. Also, there were affirmative comments about the variety and volume of digital textbook contents and voices demanding more richness and high quality contents. In addition, there were positive and negative comments about digital textbook’s functions such as search, exam, note, etc.. Some of the comments were not focused on digital textbook’s functions and instead focused on keywords such as LMS (Learning Management System), function of control students’ PC, cloud platform. Pilot school teachers commented about diversification of in-class digital textbook usage (Flipped learning, Collaboration learning, Personalized learning, etc.) and preparation (class design, lesson study, etc.).

This paper presents concepts and experiences on integrating MOOCS into traditional higher education in Romania. Three study cases on integrating MOOCs in courses at undergraduate and Master level present and discuss the opportunities in different pedagogical concepts as flipped classroom. These activities require the acquisition of new skills by students and teachers. Advantages and limitations on using this educational model from concepts to management and technology indicate the challenges that lay ahead of educators who are willing to include MOOCs in their everyday teaching activities.

Introduction to Learning Analytics for High School Teachers and ManagersVitomir Kovanovic
Presentation at the first Learning Analytics Learning Network (LALN) Event in Adelaide, Australia on Oct 22, 2019.
Abstract:
With the increased adoption of technology, institutions have unprecedented opportunities to continuously improve the quality of their services through data collection and analysis. Schools and universities now have data about learners and their contexts that can provide valuable insight into how they learn. Early attempts were directed towards mining educational data to identify students-at-risk and develop interventions. Recently, more sophisticated approaches are being deployed by researchers and practitioners. These include analysis of learner behaviour that leads to various learning outcomes, social networks and teams, employability, creativity, and critical thinking. Analysing digital traces generated through learning processes requires a broad suite of methods from data science, statistics, psychometrics, social and learning sciences.
This workshop aims to introduce teachers and educators to the fast growing and promising field of learning analytics. How digital data can be used for the analysis and improvement of student learning will be explored. First, we will provide an overview of learning analytics, its key methods and approaches, as well as problems for which it can be used. Secondly, attendees will engage in group learning activities to explore ways in which learning analytics could be used within their institutions. The focus will be on identifying learning-related challenges that are relevant to their particular context and exploring how learning analytics can be used to practically and effectively.

Abstract:
This paper presents an approach to studying relationships between students' social presence and course topics from transcripts of asynchronous discussions in online learning environments. Specifically, the paper uses topic modelling and epistemic network analysis to investigate how students' social presence is expressed across different course topics. Finally, we show how this method can be adopted to examine how students' social presence changed due to an instructional intervention. The results of this study and its implications are further discussed.

Slides from our EC-TEL'18 Paper presentation. Full paper is available at https://dx.doi.org/10.1007/978-3-319-98572-5_19
Abstract:
This paper presents a method for automated content analysis of students’ messages in asynchronous discussions written in Portuguese. In particular, the paper looks at the problem of coding discussion transcripts for the levels of cognitive presence, a key construct in a widely used Community of Inquiry model of online learning. Although there are techniques to coding for cognitive presence in the English language, the literature is still poor in methods for others languages, such as Portuguese. The proposed method uses a set of 87 different features to create a random forest classifier to automatically extract the cognitive phases. The model developed reached Cohen’s κ of .72, which represents a “substantial” agreement, and it is above the Cohen’s κ threshold of .70, commonly used in the literature for determining a reliable quantitative content analysis. This paper also provides some theoretical insights into the nature of cognitive presence by looking at the classification features that were most relevant for distinguishing between the different phases of cognitive presence.
Validating a theorized model of engagement in learning analyticsVitomir Kovanovic
Slides from our paper presentation at LAK'19 conference in Tempe, AZ. The full paper is available at https://dx.doi.org/10.1145/3303772.3303775
Abstract:
Student engagement is often considered an overarching construct in educational research and practice. Though frequently employed in the learning analytics literature, engagement has been subjected to a variety of interpretations and there is little consensus regarding the very definition of the construct. This raises grave concerns with regards to construct validity: namely, do these varied metrics measure the same thing? To address such concerns, this paper proposes, quantifies, and validates a model of engagement which is both grounded in the theoretical literature and described by common metrics drawn from the field of learning analytics. To identify a latent variable structure in our data we used exploratory factor analysis and validated the derived model on a separate sub-sample of our data using confirmatory factor analysis. To analyze the associations between our latent variables and student outcomes, a structural equation model was fitted, and the validity of this model across different course settings was assessed using MIMIC modeling. Across different domains, the broad consistency of our model with the theoretical literature suggest a mechanism that may be used to inform both interventions and course design.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

● Led by highly respected institutions
● Attracted interest of general public
○ “Tsunami in world of education”
○ “Disruptive change”
● Primarily content-focused
○ short video lectures
○ quizzes

3. MOOCs: early starts
● MOOCs were envisioned as a platform for connectivist learning
● First MOOC: 2008 Connectivism and Connective Knowledge (CCK08)
by G. Siemens & S. Downes
● Little resemblance with today’s “Coursera-style” MOOCs
○ Novel “post-industrialist” form of learning (Anderson & Dron, 2010)
○ Learning is about building connections (with content, people, and organizations)
○ Self-directed, no “formal” assessment, no certificates
○ Focus on building communities and starting up interesting conversations
○ Student interests define topics, instructors are there to support
○ Every week a new lecture on a particular topic
○ Students write blogs, research the domain, start conversation in their own social media space
■ focus on self-reflection and social interactions
○ Every week there is an aggregation email with links to all produced content

6. MOOCs: Revolution or evolution?
Three generations of distance education pedagogies (Anderson & Dron, 2010):
Cognitive-Behaviorism -> Social Constructivism -> Connectivism
Modern educational psychology:
● Learners do not acquire knowledge, they construct knowledge
● Learners are agents making decisions about their own learning tactics and approaches
MOOCS are a current stage of progress in evolution of distance education
● MOOCs were envisioned as social-constructivism 2.0
● In some aspects, xMOOCs are even a step back in online learning
○ Step back to cognitive-behaviorist learning models
○ xMOOCs were a step back because of practical reasons
● We need to look what we already know from distance/online learning (Kovanović et al., 2015)
6
7. Trends & challenges
● How we can use MOOCS for improving face-to-face courses and traditional online courses?
○ Move toward digital learning: a blend of face-to-face learning, online learning and MOOCs
(Siemens, Gašević, & Dawson, 2015)
● How to make MOOC experience more social?
○ Dual models (c+xMOOCs) (Dawson, Joksimović, Kovanović, Gašević, & Siemens, 2015)
● How assessment should look like?
○ What it means to “complete” the course? How about not having courses at all?
● Media coverage is rapidly decreasing (Kovanović, Joksimović, Gašević, Siemens, & Hatala, 2014)
○ MOOCs are not new anymore
○ Topics with a growing interest:
■ government regulations
■ adoption in different parts of the world
■ use of data & analytics
7
8. Goal: More social MOOCs
● Goal to enable for an environment in which students are able to learn together at scale
○ Online discussions should be better
■ Currently work mostly as Q/A
■ More knowledge building in discussions
○ Currently, students are having solitary experiences in MOOCs at scale
● Build on the existing models of online learning
○ Community of Inquiry model (Garrison, Anderson, & Archer, 1999)
● Use Learning Analytics and Data Mining to achieve research goal
○ Discourse analysis and social network analysis
○ Build tools that can be used by instructors
○ Extend knowledge about social learning processes

13. How different is MOOC context?
● SEM model of relationships between
presences
● Main findings:
○ Strong direct effect of teaching
presence on cognitive presence
○ Social presence acts as a mediator
between teaching and cognitive
presences
13
14. How different is MOOC context?
● SEM model of relationships between
presences
● Still in progress
○ Moderately good fit (RMSEA = 0.09)
○ Stronger direct effect of teaching on
cognitive presence
○ Lesser mediating effect of social
presence
14
15. CoI content analysis
● Besides survey, CoI coding scheme for each of the presences
● For each of the presences, quantitative coding scheme
● Message unit of analysis
15
17. Challenges of content analysis
● Very labor intensive
● Crude coding scheme
● Requires experienced coders
● Can’t be used for real-time monitoring
● Not explaining reasons behind observed levels of presences
● Used for analysis of learning long after courses are over
17
18. Research approach
● Use text analytics to address these problems.
● Develop automated content analysis system for message coding.
● Provide better operationalization of the CoI coding instrument.

19. Dataset
● Six offerings of graduate level course in
software engineering.
● Total of 1747 messages, 81 students.
● Manually coded by two coders (agreement =
98.1%, Cohen’s κ = 0.974).
● Currently coding E-learning and Digital

20. Methodology
● SVM classifier with RBF kernel.
● Parameter tuning & accuracy evaluated using nested 5-fold cross-validation.
● Extracted features:
○ N-grams
○ Part-of-Speech N-grams
○ Back-Off N-grams
○ Dependency Triplets
○ Back-Off Dependency Triplets
○ Named Entities
○ Thread Position Features
○ LSA Features
○ LIWC Features

21. Results
● We achieved Cohen’s κ of 0.42 for our classification problem
● Better than the existing Neural Network system (Cohen’s κ=0.31)
● Unigram baseline model achieved Cohen’s κ of 0.33

(Kovanović, Joksimović, Gašević, & Hatala, 2014)
22. Challenges
● Disproportionate class sizes
● Effect of the code-up rule for coding
● Context is not taken into the account
● No explanatory value
Code-up coding rule

23. In progress
• Discussions (and
students’ learning)
progresses from triggering
to resolutions.
• Content of a message
depends on the content of
the previous messages.
• Content of a message
depends on the learning
progress of a given
student.

24. Summary
● Social-constructivist pedagogies do not work well in MOOC context
○ xMOOCs: focus on content-delivery
○ cMOOCs: focus on connecting, reflecting in a self-directed way
● MOOCs
○ put more emphasis on course organization and design
○ building community a challenge
○ focus more on remembering than on understanding and evaluating
○ need for a more social experience in MOOCs
● Community of Inquiry model
○ Widely used, hard to adopt
○ Automated coding of messages:
● An overview of student progress in development of cognitive presence
● Support instructional interventions
● Further understanding of CoI model, particularly in MOOC context
● More detailed operationalization of CoI coding scheme
