New job, new papers to read. During my search for papers on Educational Data Mining, there aren't many, I stumbled on several papers by researchers from the University of Sydney. This group has come up with a visualisation of collaboration they call Wattle trees and it simply is brilliant! The example below, taken from Wattle trees: What'll it tell us, illustrates that some have started the trajectory from simple statistics to sophisticated visualisations. I feel at home :-).
