When multiple authors-especially student authors-collaborate to write a single work, quality control is very important. The instructor/editor rarely has time enough to review each contribution multiple times until it measures up. The open-source Expertiza platform distributes the task of reviewing among all the students. Students select topics they want to write on and topics they want to review. They fill out a rubric assessing each submission they are assigned. Then they and the authors engage in a rubric-based, double-blind communication about revisions. Expertiza enables metareviewing, teamwork, and team-member assessment. It offers students copious feedback on their contributions and provides instructors with a rich variety of information to use in assigning grades.
