5. Research about Learning Objects But what?

6. What is a Learning Object? Not a good idea

7. What is a Learning Object? Not a good idea

8. How many learning objects are published? How many learning objects are reused? How many objects are produced by each teacher? How many times a learning object is reused? What is the average size of a LO repository?

10. Learning Object Repositories

11. Size of Repositories Repository Referatory OCW LMS IR

12. A medium sized LMS has more objects than MERLOT

13. Distribution of Objects

14. There is a long tail of resources How can we find them?

15. Growth – in Objects

16. Growth in Contributors

17. Growth is Linear Ouch!

18. But there is hope…

19. Connexions Growth in Contributors

20. Connexions Growth in Objects

22. Objects per Contributor LORP - LORF Lotka / Log-Normal “ fat-tail”

23. Objects per Contributor OCW - LMS Weibull “ fat-belly”

24. Objects per Contributor IR Lotka high alpha “ light-tail”

25. The key is the engagement There must be a value proposition

26. Engagement

27. If only our LMSs could be our repositories OERs could be the key

28. Reuse of LO

29. Reuse is the raison d’être of Learning Objects But very little is know about actual reuse

30. Reuse Paradox

31. Measuring Reuse

32. Measuring Reuse

33. Measuring Reuse ~20%

35. REUSE IS HAPENNING with or without us Let’s help to make it easier

36. Our understanding of Re-use needs to be re-examined We need more studies!

37. Popularity vs. Reuse

38. Distribution of Reuse

39. We call this line of research Learnometrics Hey, it was good for my thesis 

44. Learngin Analytics or Educational Data Mining or Educational Research The same or different?

46. The questions are the same The difference is in the kind of answers
