There is a growing trend for students to create and share self-assessment questions in their subject, as advocated by the contributing-student pedagogy (CSP). For subjects with large enrolments, this process can be facilitated by educational technology. PeerWise is an example of such technology. It is free, web-based software that allows students to author, share, answer, and provide feedback on multiple-choice quizzes in a collaborative and constructivist fashion. While it is popular, it is unclear to what degree it facilitates student learning. To evaluate its effectiveness, we introduced PeerWise into a second-year psychology subject. We measured the extent to which it increased scores in the final exam. We found that PeerWise did significantly increase exam scores, so was a useful learning aid %K Computer-based learning %K contributing-student pedagogy %K collaborative learning %K online learning %K interactive learning environments %K learning communities %U https://journals.sagepub.com/doi/full/10.1177/1475725718764181
