No reuse? My eyes must be fooling me!
One of my bright PhD. students, Joris, has been working on information visualization techniques for learning object repositories.
In this clip, you can see what kind of reuse is happenig in our ALOCOM repository (developed by another one of the bright people that work with me: Katrien!). Basically, the repository contains content that has been automatically de-composed into smaller fragments that are more easy to reuse – more details on-line.
In this visualization, a line between two dots implies that the content (fragment) represented by the one dot is reused in the content that the other dot visualizes. One minute into the clip, it should be obvious that there is quite a bit of reuse going on!
