Supplemental Instruction

Supplemental Instruction 2021 - 2022 Academic Year

Learning with a group of peers is a powerful tool!

Supplemental Instruction (SI) sessions offer students the opportunity to master course material within a community of learners. The SI program gives students an environment to engage with, ask questions, and review lecture material with their peers. SI supports courses in Biology, Chemistry, Data Science, Economics, Math, Management Science, Philosophy, Physics, Psychology, Engineering, and Statistics.

  • SI sessions are facilitated by Peer Leaders who have successfully completed the course at UC San Diego and are trained in facilitating sessions to engage students in active problem-solving and discussion
  • SI sessions meet weekly for 80 minutes or 50 minutes 3 times a week.
  • In person and Zoom sessions are offered

In 2020 - 2021, the SI Program supported:

  • 44 courses in 7 departments/divisions
  • 5,298 students participated in and contributed to a total of 51,190 visits 

Program assessment over 5 years demonstrates that participation in Supplemental Instruction supports students in obtaining a half letter grade higher than peers not participating in the program.

In Winter 2022, we will be offering in-person and virtual session options for select courses. Please review the SI Schedule for more information regarding your course.

Why do students utilize Supplemental Instruction?

  • “The SI program strengthened my grasp and understanding of basic knowledge, thus laying a good foundation for the knowledge I will learn later” - Phys 1B (Summer Session 2 2021)
  • “Great for revision before the major quizzes, and definitely helped me gain confidence regarding my grasp on the material." - Physics 2A (Fall 2021)
  • “I feel more confident in my abilities after attending SI. My SI leader was very kind and engaging in the sessions. I felt included and respected which encouraged me to attempt participating more and ask questions.” - Math 10B (Summer Session 1 2021)
  • “After consistently attending SI sessions I had a better understanding of course materials, which helped me improve my grades on tests and quizzes.” - Math 20C (Spring 2021)
