  1. OER Recommender and OER Glue Joel Duffin & Justin Ball Tatemae

  2. Outline Background and Research Goals System Description EvaluationIssuesWhat's next? 

  3. Background Center for Open Sustainable Learning (COSL)Utah State University, David Wiley eduCommons - OpenCourseWare CMS OCW Finder - http://ocwfinder.orgSimple, popular search engine for OpenCourseWare Folksemantic - MOCSL User centered tools for open education - Ozmozr, Make a Path, Send2Wiki, Annorate, Scrumdidilyumptious

  4. How do we get people to USE OER effectively?"most of the OER you see at conferences encourages bad learning design" http://tinyurl.com/34qsux6

  6. Research Goals Increase effective use of OERs by cross linking OpenCourseWares and NSDL OERs • Widgets and APIs for OER providers • OER recommendation algorithms and architectures • Recommendation display • Adoption

  7. Related Resources Cross Repository Links

  8. Related Resources Widget

  9. Evaluation QuestionsHow is OER Recommender being used?How well is it accomplishing goals? How can it be improved? MethodsAnalyticsUser tests and questionnaires

  10. Strengths It is being used eduCommons and OpenLearn are primary adopters Recommendations attract interest (11% click through rate) Areas for improvement: Algorithms (ranking & learning) Display Ease of adoption Coverage (more resources) Conclusions

  11. Learning from user implicit and explicit feedback Presentation bias Narrowing scope of search and recs Dead links Catalog pages Duplicate entries Incremental update Coverage Score cutoff level Confidence vs reliability OER rank (getting beyond text analysis) Faceted search Metadata vs content Personal recommendations Scaling up processing (hadoop, mahout, cascading, bixo) Activity specific recs  More & better widgets Issues

  12. Evaluation Criteria Related Novel Diverse Popular Changed / updated • Task-appropriate • Learner • Do well in class • Explore interests • Teacher • Use resource • Remix (use part of a resource)

  13. Try It! Add Cross-Site Recommendationsto Your Site Examplehttp://ocw.usu.edu/English/english-1010 Instructionshttp://www.folksemantic.com/widgets Add Your Resources to the Index

  15. Supports effective teaching  and learning by "glueing" together open content and services  Embracing open Integrates with everyone Easily extensible

  16. Modifies pages in place, using content where it exists instead of copying into an LMS Provides functionality through integrations Recommends OERs to authors Allows extension via JavaScript We are looking for partners - joel.duffin@gmail.com

  17. Help Evaluate OER Recommender! Online questionnaire (15 min) Teachers OER providershttp://oerrecommender.org
