Supplemental Instruction

What is Supplemental Instruction (SI)?

Supplemental Instruction (SI) is a free peer-led program that can help you succeed in historically difficult courses.

Our guided study sessions encourage you to collaborate with other students while also teaching you what to learn and how to learn it. With each session, you'll develop your critical thinking, teamwork, and communication skills.

How does SI work?

SI Leaders—people who have previously done well in a course—act as role models in peer-assisted study sessions.

SI Leaders:

  • Are trained to make group study sessions efficient and effective
  • Work with specified faculty
  • Attend all class lectures
  • Take notes

SI sessions are regularly scheduled, informal review sessions in which you:

  • Compare notes
  • Discuss readings
  • Develop organizational tools
  • Predict test questions
  • Learn how to learn while learning what to learn

What are the differences between SI and peer-tutoring?

Supplemental Instruction (SI) Peer-tutoring (PT)
1 SI Leader works with a group of students. 1 peer tutor works with 1 student at a time.
The SI Leader attends a section of the course or lab. The peer tutor is not required to attend a section of the course.
The SI Leader works with a specified faculty member. The peer tutor is not associated with 1 designated faculty member.
The SI Leader works with and is supervised by an SI Coordinator. The peer tutor reports to a learning lab manager.
SI Leader training is more intense and long term. Peer tutor training typically requires half a day. 

Why should I choose SI?

The main benefit for joining SI is higher average grades.

Students who participate in SI earn, on average, 1 letter grade higher than students who do not participate.

SI also prepares you for success in future courses by teaching you the study skills you need to finish your education at the top of your game.
