The document discusses metrics for measuring learning objects and repositories. It examines metrics like the size and growth of repositories, distribution of objects and contributors, and reuse of learning objects. The document proposes that studying empirical patterns in learning object data can help understand influence and impact, and defines this field of research as 'Learnometrics'.

- 1. Learnometrics: Metrics for Learning (Objects) Xavier Ochoa Escuela Superior Politécnica del Litoral Guayaquil, Ecuador
- 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?
- 11. Size of Repositories Repository Referatory OCW LMS IR
- 12. A medium sized LMS has more objects than MERLOT
- 14. There is a long tail of resources How can we find them?
- 15. Growth – in Objects
- 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
- 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!
- 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
- 47. Gracias / Thank you / Merci Xavier Ochoa [email_address] http://ariadne.cti.espol.edu.ec/xavier Twitter: @xaoch
