Exploring Peer Review in the Computer Science Classroom (0907.3456v1)

Abstract: In computer science, students could benefit from more opportunities to learn important, high-level concepts and to improve their learning skills. Peer review is one method to encourage this by providing students with the opportunity to evaluate other people's work and to receive feedback on their own projects. This allows for rich learning experience but it is not immediately obvious how to create a programming project review that will improve the students' conceptual understanding, require higher level thinking, and be engaging. The current literature does not typically address differences between review implementations or provide reasons for design decisions. This work explored how two different types of reviews affected the students' learning of concepts, high-level thinking, and engagement. There were indications that the type of review affected how well students addressed the concept they were reviewing and the comments' length. This shows that the review's type may affect student engagement and conceptual learning. There were also differences in how they reviewed the concepts of Abstraction, Decomposition, and Encapsulation, suggesting that the concepts are being learned in different ways. Both of these results have an impact on the use of peer review computer science but need further investigation.
