  7. 7. Open Social Learning 8
  8. 8. Education: What’s the problem? Access More than one-third of the world’s population is under 20. By 2006, 100 million qualified to enter a university will have no place to go. To meet this staggering demand, a major university needs to be created each week. — Sir John Daniel (1996) 9
  9. 9. Education: What’s the problem? Engagement 88% of high school dropouts have passing grades. — Gates Foundation study Silent Epidemic (2006) 47% of dropouts say classes are not interesting . 60% find video lectures boring . 60% read less when using e-textbooks.
  10. 10. The Long Tail of Education Traditional 11
  11. 11. The Long Tail of Education Traditional MIT OCW: 9m users/yr iTunes U: 300m downloads Khan: 30k videos/day Open Education 12
  12. 12. Education: Still a problem Engagement 60% find video lectures “boring”. Great video and talented presenters. My only complaint: I’d like to interact with others who are viewing the resources. Creating a one-way flow of information significantly misses the point of interacting online. — George Siemens ( 2007) 13
  13. 13. What Engages Our Students? 95% spend 10-15 hrs/wk on Facebook 80% go to Wikipedia 55% use IM for homework 14
  14. 14. What Engages Our Students? $11B market “Im calling for investments in educational technology that will help create ... educational software that is as compelling as the best video game.” — Barack Obama (2011) 15
  15. 15. Imagine “Open Social Learning”Imagine a Facebook wherethe point is to study together, not trade pictures and jokes. Imagine a World of Warcraft where students earn points by helping each other learn.Not educational games. Education experience itself isstructured as a “social game”.

  19. 19. OpenStudy is…“a social platform for learnerswho want to help each other study” “you’re no longer alone—you have the world’s biggest classroom to turn to, any time, anywhere” “a global study group” “global element is important…users will almost always find someone online in the study groups” “one of ten most innovative companies in education” 20
  20. 20. OCW + OpenStudy
  21. 21. Community of learners No boundaries From 3rd graders to college students to professionals Anytime Anywhere
  22. 22. Community of learners Multi-student study sessions “Make the world your study group”
