Supplemental Instruction (SI) is an academic support program developed by Deanna Martin, at the University of Missouri at Kansas City in 1973, utilizing peer-assisted study sessions to enhance student performance and retention (Widmar, 1994). The goals of SI include improving students' grades in traditionally difficult courses, reducing the attrition rate in those courses, and helping students develop study strategies to assist them in future courses (Behrman, Dark, & Paul, 1984; Martin, Blanc, & DeBuhr, 1983; Peters, 1990; Prather, 1983; Wolfe, 1987).
