Abstract:
PeerWise is a collaborative web-based system that engages students in the creation and evaluation of a test bank of multiple-choice questions. Previous studies involving two large CS1 courses in New Zealand have provided preliminary evidence that PeerWise usage is positively correlated with exam performance. In addition, it was reported that the student generated assessment questions were mostly free from errors and were clearly written, and the students appeared to positively value the system. Here we report on the first use of PeerWise in a CS1.5 course (second programming course) in the United States. Although the usage model was modified slightly to accommodate pedagogical factors, we highlight similar positive outcomes to those observed in New Zealand. Of particular note, students who were most active using PeerWise improved their rank in class relative to their peers who were less active.
