Have just read the following paper from ASCILITE 2015 (recently held in Perth)
Liu, D. Y., Richards, D., & Atif, A. (2015). An enhanced learning analytics plugin for Moodle : student engagement and personalised intervention. In T. Reiners, B. R. von Konsky, D. Gibson, V. Chang, L. Irving, & K. Clarke (Eds.), Globally connected, digitally enabled. Proceedings ascilite 2015 (pp. 180–189). Perth.
The paper reports on a design-based research project at Macquarie University in Australian aimed at enhancing the Moodle Engagement Analytics Plugin (MEAP) and producing what they label MEAP+
Part of the enhancements made related to recent comments from Marcus regarding the intelligibility of representations used by learning analytics tools.
It appears that MEAP+ is still in beta. The source code is available upon request.
