The BushGrapher is a plugin that allows instructors to plot graphs describing the interactions of students in discussion forums.
The Bushgrapher was developed at Lingnan University by staff from
the Teaching and Learning Centre. The project was funded by an
internal Teaching Development Grant (TG10B9) from funds
provided by the University Grants Committee. The Bushgrapher has been released under a GNU (see below) in order that
other UGC funded institutions might benefit from the work undertaken
by Lingnan University staff.
The Bushgrapher provides a means of visualising the interactions between student postings in a forum. The Bushgraph produced allows a teacher or researcher to visualise student interactions as a temporal web of interactions between individuals engaged in discussion on a forum. The current release version is for internal research use within an institution only and not recommended for research that needs to ensure high levels of student privacy.
