Supplemental Instruction (SI) is a formal support program designed to assist students in mastering course concepts and, at the same time, to increase their competence in learning how to learn the concepts of the discipline more effectively and efficiently. SI links course content and cognitive skills development through a regular schedule of out-of-class sessions. Trained student SI leaders guide the sessions by encouraging students to think about, question, and confirm their understanding of the content while learning more effective strategies of studying and learning the subject. When SI is available in conjunction with a specific section of a difficult course, attendance at one, two, or all sessions is optional.
