Important information regarding the continuation of Supplemental Instruction sessions during online instruction.

Supplemental Instruction will continue to be offered in the period of online delivery of courses. There will be no in-person SI sessions. SI Leaders will facilitate sessions using the WebEx Video Conferencing Platform.

Sessions will be hosted online on the same days and times as regularly scheduled SI sessions. Participants can find information about session days/times and how to access the virtual sessions by visiting their SI Leader's website.  Participants can download the "How to Access Your SI Session" Document to learn more.

Due to potential unforeseen obstacles SI Leaders may encounter as they move to online delivery, some sessions may be modified, cancelled, or suspended until in-person sessions can resume on campus.

What is SI?

Supplemental Instruction (SI) is an internationally recognized academic support program. SI is a voluntary program that offers free, regularly scheduled study sessions for traditionally difficult courses. SI sessions are lead by current ISU undergraduate students who have successfully completed the course.

We support more than 30 courses in the following subject areas:

  • Accounting
  • Animal Science
  • Biology
  • Chemistry
  • Economics
  • Engineering
  • Math
  • Physics
  • Psychology
  • Statistics, and more

Proven to Work

Our methods of collaborative study sessions have shown an average of over one-half letter grade improvement amongst students who regularly attend SI sessions. See more of our data here.

Students who participate in SI:

  • Learn how to learn while learning what to learn.
  • Work collaboratively with peer students in a facilitated environment.
  • Receive support from a trained, educated SI Leader.

Our data suggests that the more often students attend, the higher their final grades will be in the course. We recommend attending SI at least once per week.
