What is Supplemental Instruction?

SI Picture

What is SI?

Supplemental Instruction (SI) is a nontraditional form of tutoring that focuses on collaboration, group study, and interaction for assisting students in undertaking "traditionally difficult" courses. SI targets courses with a minimum 30% rate of students that drop, withdraw, or fail, and then provides a trained peer who has successfully negotiated the course to assist its future students.  Through 50-minute SI sessions, students are provided with course-specific learning and study strategies, note taking and test taking skills, as well as the opportunity for a structured study time with peers.

SI Session

What is an SI leader?

SI sessions are facilitated by academically successful students known as SI leaders, who have previously excelled in the course and have received training on guiding collaborative group study sessions. SI leaders attend all of the assigned lectures and participate as a traditional student within the course.  SI leaders plan and use a variety of teaching and learning methods within 3-5 one-hour study sessions to demonstrate effective study strategies that a student can apply to any class thus providing an opportunity for students to learn how to learn while learning what to learn.

Benefits of attending SI

SI is a resource offered by the Student Learning Assistance Center (SLAC) and available to any student registered in an SI-targeted course. Attendance can be voluntary, however, because data collected has proven that students who attend regularly (at least one session a week) on average receive a final grade one half to a whole letter grade higher than their classmates who did not regularly attend! SI is sometimes often included as a participation grade.
