Teaching a course at a university can be a lonely experience. Traditionally, there is little peer review and support for teaching activities, in contrast to the culture and practice of research, in which peer involvement, encouragement and review are all considered vital.
Teaching quality is also an increasing important aspect of university life, and one for which some kind of peer interaction and review is recognised as a good idea. However, finding the right framework and process for peer interaction can be problematic.
One process that has proved to be beneficial at Monash University is the Peer Assisted Teaching Scheme, devied and run by Angela Carbone. Angela gave a seminar at RMIT on June 17th, 2011 about this scheme. Here are some relevant links.
