The SI leaders are the key people in the programme. They are presented as model “students of the subject.” As such they present an appropriate model of thinking, organization and mastery of the discipline. All SI leaders take part in an intensive two day training session. This training covers such topics as how students learn as well as instructional strategies aimed at strengthening student academic performance. SI leaders attend all class sessions, take notes, read all assigned material, and conduct a number of SI sessions each week. They gain extensive facilitation skills from running the sessions.
