We assessed the effects of using LearnStar[TM], an interactive, computer-based teaching tool, as an in-class exam review method. Students with higher LearnStar review scores had higher grades. Furthermore, students' satisfaction ratings indicated that LearnStar reviews were more enjoyable and conducive to participation than traditional reviews. However, students who reviewed using LearnStar did not have significantly higher exam scores or coursegrades compared to students who had traditional reviews. Future research directions include measuring different aspects of students' engagement in courses and examining the effects of using tools such as LearnStar for other in-class activities such as brief quizzes or polls.
