Supplemental Instruction (SI) is a semester-long program of undergraduate academic support. Student attendance is voluntary. For students in high-expectation classes, SI is a chance to learn best strategies from a trained peer leader who has taken the same class and done well. SI is also about getting together with other people in the class to compare notes, discuss questions, share strategies for studying, and practice before tests.
Students who attend SI sessions average higher grades and pass challenging courses more often than those who do not attend SI. And the skills learned in SI for one class remain with students to increase learning speed, understanding, and proficiency in other classes.
