Abstract Title: Peer Evaluations of Video Lab Reports in an Introductory Physics MOOC
Abstract: Assessing student performance becomes challenging when course enrollment becomes very large (~10^5 students). As part of an introductory physics Massive Open Online Course (MOOC) offered by Georgia Institute of Technology, students submit video reports on force and motion labs. Peer evaluation of reports provides the primary method for evaluating student laboratory work. This paper describes the methods developed and used to guide students in evaluating each others' video lab reports when the course was offered in Summer 2013 and Fall 2013. Results of how students peer evaluation compares to experts evaluation will be presented. In particular, we will discuss how different guidance provided to students in Summer 2013 and Fall 2013 affect student evaluation behavior.
