Supplemental Instruction (SI)

Supplemental Instruction Logo

Supplemental Instruction (SI), is an academic assistance program that utilizes peer-assisted study sessions.  SI sessions are regularly scheduled, informal review sessions in which students compare notes, discuss readings, develop organizational tools, and predict test items.  Students learn how to integrate course content and study skills while working together.  The sessions are facilitated by “SI leaders”, student who have previously done well in the course and who attend all class lectures, take notes, and act as model students.


SI is a free service offered to all students in a targeted course.  SI is a non-remedial approach to learning as the program targets high-risks courses rather than high-risks students.  All students are encouraged to attend SI sessions, as it is a voluntary program.  Students with varying levels of academic preparedness and diverse ethnicities participate.  There is no remedial stigma attached to SI since the program targets high-risks courses rather high- risks students.


“I really enjoyed the experience, being able to help my peers through such a challenging class was very rewarding and reinforced my understanding of chemistry. Setting up activities for the session and trying to lead students through the activities were at times as challenging for me as for the students. However, as the semester went on the dynamics of the group picked up, each session began to feel more and more effective. “
- Farshud Sorourifar (SI Leader)

Supplemental Instruction has helped me grow into a better leader and has provided me new opportunities to improve as both a student learner and as a professional.”
Taylor Bashara (SI Leader)

"Being an SI Leader has been an immense growing experience for me. It has helped me to overcome much of my social anxiety through requiring that I be in constant communication with both students and faculty. It has also aided me in becoming a confident leader and an active, contributing member of the MiraCosta academic community."
Aaron Tolopilo (SI Leader)
