摘要:Supplemental Instruction (SI) has been a powerful tool for improving retention rates at colleges and universities around the country. It is backed by decades of research and a successful traditional model that institutions can comfortably rely upon. This study reports that faculty-led SI, a significant departure from the traditionally defined and implemented peer-led SI model, has a number of measureable advantages over the traditional peer-led model. While it was observed that student grades on exams and in the course increased more for those who regularly attended faculty-led SI, students also reported that they preferred it to the peer-led sessions.
