Investigations into Deep Knowledge Tracing: From Cold-Start to Real Life

Dr Ryan Baker

Associate Professor at the University of Pennsylvania, and Director of the Penn Center for Learning Analytics, US

Speech Abstract

In the last several years, there has been increasing interest in studying different variants of deep knowledge tracing (DKT). However, deep knowledge tracing has remained largely an algorithm studied rather than an algorithm used. Real-world adaptive learning systems generally still use algorithms developed over a decade ago, or even simpler heuristics. In this talk, I discuss our research group's investigations into key issues relevant to the use of deep knowledge tracing, complementary to other research efforts going on around the world and in particular in East Asia. I will talk about two tracks of research in my group. In the first track of research, we investigate the use of DKT to estimate latent knowledge in terms of interpretable skills that can be carried outside the adaptive learning system. We propose a simple extension, applicable to all DKT family algorithms, and evaluate the degree to which DKT family algorithms can predict latent knowledge demonstrated on tests outside the learning system. In the second track of research, we study the degree to which DKT family algorithms can solve cold-start problems, producing acceptable knowledge tracing estimates earlier in student work on a new skill. I conclude with a discussion of directions needed for DKT family algorithms to achieve their full potential and scale in real-world use.

Ryan Baker is Associate Professor at the University of Pennsylvania, and Director of the Penn Center for Learning Analytics. His lab conducts research on engagement and robust learning within online and blended learning, seeking to find actionable indicators that can be used today but which predict future student outcomes. Baker has developed models that can automatically detect student engagement in over a dozen online learning environments, and has led the development of an observational protocol and app for field observation of student engagement that has been used by over 150 researchers in 7 countries. Predictive analytics models he helped develop have been used to benefit over a million students, over a hundred thousand people have taken MOOCs he ran, and he has coordinated longitudinal studies that spanned over a decade. He was the founding president of the International Educational Data Mining Society, is currently serving as Editor of the journal Computer-Based Learning in Context, is Associate Editor of the Journal of Educational Data Mining, was the first technical director of the Pittsburgh Science of Learning Center DataShop, and currently serves as Co-Director of the MOOC Replication Framework (MORF). Baker has co-authored published papers with over 300 colleagues.

Speaker Abstract(摘要)

親子共讀是父母、幼兒教育者和其他照料者幫助兒童獲得語言與文字認知發展與學習行為技能的一種方式。 對話式閱讀 (Dialog Reading)是一種以證據為基礎的常用親子共讀策略,其中PEER(Prompt, Evaluate, Expand, Repeat)更能促進親子互動之學習行為。然而由於父母並未受過對話式閱讀策略之訓練,因此並未表現出親子共讀效果。另外因父母需兼顧工作,較沒有充裕的時間陪伴兒童進行閱讀。為了能夠改善父母不會運用PEER策略與沒有時間陪兒童做親子共讀等問題,故運用AR技術發展具PEER親子共讀策略的AR繪本。在此AR繪本上,能引導兒童利用行動載具進行PEER之共讀,也探討此AR繪本對兒童學習成效與行為分析的影響。

The Future of Education: New Space, New Knowledge and New Ontology

Professor Chen Li

Vice President, Beijing Normal University

Speech Abstract

Prof. Li Chen will deeply elaborate how cyber space is transforming education on essence in three aspects. Firstly, Prof. Chen will explain the impact on education of disruptive technology. The cyberspace is a kind of disruptive technology which is an information space with different characteristics from physical space and social relation space. Now cyber space is transforming from two spaces to three spaces. Secondly, Prof. Chen will issue that in the cyber space knowledge is extending to all kind of experience and different from traditional knowledge the book. Prof. Chen will present her research findings on knowledge in the cyberspace. Thirdly, Prof. Chen will issue that education ontology is changing to connection. Prof. Chen is going to present the experimental study on cMOOC. At the end of the speech, Prof. Chen will call on the researchers in education technology to pay attention on revealing new foundation of education during applying new technology into education.

Speech Title:
Awarding Skill Improvements based on Behaviour Pattern Extraction and Analysis

Professor Maiga Chang

Full Professor, Athabasca University, Canada

Speech Abstract
Educational games and gamification learning systems usually provide learners rewards when they have progress on solving learning quests and/or doing learning activities. But how to give learners an appropriate reward that reflects the efforts they have taken and the skill improvements they have made? This talk will start with the showcases of couple of educational games that can help learners improve their meta-cognitive skills (e.g., problem solving, associative reasoning, evaluation and accuracy, and planning and organiz ation) and language speaking skill. These educational games record learners actions taken in the games and give learners points, virtual currency and virtual items to award their learning achievements and progress (i.e., skill improvements). This talk will then use the real game-play data collected from a commercial mobile educational game as example to explain the process of identifying and extracting learners' bahaviour patterns and calculating a learning quest/activity's general difficulty for most of learners as well as its difficulty for the particular learner. At the end of the process, the educational games and gamification learning systems is capable of awarding the learners proper rewards based on their efforts, improvements, and achievements.
