his article describes and evaluates several peer evaluation tools used to assess student behavior in small groups. The two most common methods of peer assessment found in the literature are rating scales and single score methods. Three peer evaluation instruments, two using a rating scale and one using a single score method, are tested in several management courses to examine their effectiveness. All three instruments demonstrate acceptable levels of reliability and are found to be correlated with individual performance measures. The article concludes with a discussion of the advantages and disadvantages of each instrument.
As collaborative or team-based projects become more popular in both secondary and post-secondary classrooms, instructors are looking for ways for group mem bers to effectively evaluate one another. Constructing effective evaluation tools can be a daunting task. As shown by a review of literature, best practices include (1) building a foundation in the classroom that supports collaborative evaluation, (2) creating effective evaluation tools by articulating specific criteria and ensuring honest student participation (3) implementing formative feedback during the col laborative experience, (4) formulating summative feedback at the conclusion of the experience, and (5) assessing the collaborative evaluation process.
