Revision by means of computer-mediated peer discussions

In this article, we provide a discussion on our revision method (termed prescriptive tutoring) aimed at revealing students' misconceptions and misunderstandings by getting them to solve physics problems with an anonymous partner via the computer. It is currently being implemented and evaluated in a public secondary school in Singapore, and statistical analysis of our initial small-scale study shows that students in the experimental group significantly outperformed students in both the control and alternative intervention groups. In addition, students in the experimental group perceived that they had gained improved understanding of the physics concepts covered during the intervention, and reported that they would like to continue revising physics concepts using the intervention methods.
