Zing´Em: a Web-based Likert-scale Student-Team Peer Evaluation Tool

We describe the design and implementation of a peer evaluation system named Zing´Em, in use for 3 years and over 60 course sections. Zing´Em supports Likert-scale items, is easy for professors to set up, simple for students to use and provides analyses of teams for the professor to use in grading and possible interventions. This paper documents the design goals, implementation tradeoffs and experience of users. We critique the system and suggest improvements for future work.
