Intelligent vs. Adaptive 1. Intelligent but not adaptive (no student model!) 2. Adaptive but not really intelligent 3. Intelligent and adaptive Intelligent ES Adaptive ES 2 3 1

Adaptive E-Learning Systems Major issues for adaptation in education – greater diversity of users “user centered” systems may not work – new “unprepared” users traditional systems are too complicated – users are “alone” limited help from a peer or a teacher

Research updates Recommendation Social Media Novelty Learners’ Analytics

UMAP 2011 Finding someone you will like and who won't reject you Analyzing user modeling on twitter for personalized news recommendations Towards open corpus adaptive hypermedia: a study of novelty detection approaches Open Social Student Modeling: Visualizing Student Models with Parallel IntrospectiveViews

Social Media Now&Future Leveraging micro- blogging activities on Twitter Semantic enrichment enhances the variety and quality (#hashtags) Different user modeling strategies (temporal profile patterns) can improve recommendation quality – Personalized Vialogues recommendations? – Moderator profile/participant profile?

Knowledge prediction Now&Future problem difficulty is an even more important predictor than student proficiencies on the required skills

Novelty Now&Future Detect relevant and NEW content by automatic text analysis More evaluations are required – Recommend courses outside of TC, Columbia Univ.? – Recommend “novelty” resources from Docdel?

Learner Analytics Now&Future Open Student Model – Awareness – Increase learning –…–… Open Social Student Model – knowledge-based and social-based guidance combined rules!
