Launching a Peer Supplemental Instruction Program for an Introductory Biology Course

For the first time at Georgia Gwinnett College, a supplemental instruction (PSI) program was designed to provide peer-led instruction on a) principles of biology, chemistry, mathematics and b) academic skills e.g. self-regulated learning, strategies in studying and test-taking. PSI for Principles of Biology (BIOL1107K) was carried out by PSI leaders who previously earned a grade of ‘A’ or ‘B’ in BIOL1107K, received training on tutoring practices and worked with faculty to develop active learning exercises/worksheets for PSI sessions. PSI was open only to students who earned a grade of ≤ 75% on the first exam across four BIOL1107K sections. Comparison of exam grades revealed that PSI student performance was not significantly different from control (students who earned a grade of ≤ 75% on the first exam but did not enroll in PSI). The challenges at an institution lacking a PSI culture and strategies to encourage student commitment will be discussed
