Supplemental Instruction (SI) was designed at the University of Missouri- Kansas City (UMKC), and is an academic model that uses peer-facilitated study sessions for students taking historically difficult courses. SI is provided for all students who want to improve their understanding of course material and improve their grades. The SI sessions are free, regularly scheduled, informal review sessions, and develop organizational tools. These sessions are led by SI leaders; who are students who have previously taken the course and done well.
SI leaders have previously taken the course and received an A or B, then recommended by a faculty member. They attend all lectures and hold two-three one hour review sessions per week, reviewing the material presented in class. The sessions are presented with a variety of interactive activities, and have the students think critically about the lectures they hear and books they read.
