Research about Learning Objects But what?

What is a Learning Object? Not a good idea

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?

Learning Object Repositories

Size of Repositories Repository Referatory OCW LMS IR

A medium sized LMS has more objects than MERLOT

Distribution of Objects

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

Growth – in Objects

Growth in Contributors

Growth is Linear Ouch!

But there is hope…

Connexions Growth in Contributors

Connexions Growth in Objects

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

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

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

The key is the engagement There must be a value proposition

Engagement

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

Reuse of LO

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

Reuse Paradox

Measuring Reuse

Measuring Reuse ~20%

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

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

Popularity vs. Reuse

Distribution of Reuse

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

Learnometrics
Study empirical regularities on data
Develop mathematical models
To understand the influence/impact
Produce useful metrics

Learning Analytics

Educational Data Mining?

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

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