P523: Clickers work
A redesign of General Chemistry I (Chem 110) at Penn State Berks included the implementation of peer mentors, online quizzes, pre-class assignments, and most importantly a student response system with corresponding questions related to each lecture. This study reports the effects of the student response system on student outcomes before and after it was implemented into the course design. The data revealed that students who used the student response system in Chem 110 compared to students that did not previously use clickers improved their grade at their first attempt at the class from a 1.64 to 2.38 on the GPA scale, while withdrawals decreased from 0.30 to 0.08. Other significant differences such as average and high grades as well as attempts were found in this study. The same analyses were performed on General Chemistry II, Organic Chemistry I, and Organic Chemistry II students, as well as the effects of the student response system on outcomes by student gender in each class.
