Peer Assessment: Benefits of Group Work


Teaching ProfessorWith the increased use of group work in college courses, exploration of the role of peer assessment has broadened, as has its use. In one survey, 57 percent of students reported that their faculty had incorporated peer evaluations into group assignments. We’ve done articles on this topic before, but mostly we’ve highlighted resources, specifically good instruments that direct peers to provide feedback in those areas known to influence group outcomes. Recent literature includes a variety of peer assessment systems (find three examples referenced at the end of this article), many of them online programs that expedite the collection, tabulation, and distribution of the results. Here’s a list of the benefits of making peer assessment part of group learning experiences.

Peer assessment can prevent group process problems. Several studies show that it helps, and sometimes virtually solves, one of the most egregious group problems: free riding, as in students not doing their fair share of the work. One study found that the very possibility of having peer evaluations improved the performance of group members. Of course, that benefit is enhanced when peers receive feedback from each other as they are working together as opposed to when the project is finished.

Formative peer assessment also improves individual and group performance. Even if the group is not experiencing major problems, formative feedback from peers can help individual members fine-tune their contributions and help the group increase its overall effectiveness. Some of the processes faculty are using to achieve this benefit include individual and group responses to the feedback. Individual students comment on feedback from the group via an email to the teacher, and groups use the feedback to develop an improvement plan. They also make note of what the group is doing well. Online peer assessment systems make multiple exchanges of formative feedback possible, which is helpful when the groups are working on complex, course-long projects. The Brutus and Donia system resulted in measurable individual improvement during a second semester when the system was used. In other words, students took what they’d learned about their performance in the group and acted on it the following semester.

Peer Assessment that Improves Performance in Groups


Peer assessment in groups has been shown to effectively address a number of group process issues, but only if the peer assessment has a formative component. Many studies have shown that if peer assessment is used at the end of a group project, group members will punish their dysfunctional members—those who didn’t do work, didn’t turn work in on time, didn’t come to meetings, and didn’t do quality work—but they won’t confront those group members when they commit those dysfunctional behaviors. After-the-fact peer assessment gives the teacher input on who did and didn’t contribute in the group, but it doesn’t change what happened in that group or help students learn how to confront group member problems when they emerge.

Group Work Challenge: Assessing Team Members


Teachers who use group work frequently incorporate some sort of peer assessment activity as a means of encouraging productive interactions within the group. If part of the grade for the group work depends on an assessment by fellow group members, students tend to take their contributions to the group more seriously. Often teachers use some sort of point distribution system where a given number of points must be divided among members, and they cannot be distributed equally. The problem with these systems is that the feedback they provide lacks specificity. Students don’t know what they are doing that accounts for the score they’ve received, and this makes improvement less likely.

Peer Assessment is Not an Elixir for All Group Work Challenges


Here’s an empirical result I would not have predicted. It emerged in a meta-analysis of research on group learning activities as reported in 32 studies published in Teaching of Psychology between 1974 and 2011. I’ll be doing a detailed highlight of the entire article in an upcoming issue of The Teaching Professor. But the finding that surprised me involved the use of peer assessment within groups: “Our hypothesis of better learning outcomes with peer assessment was not supported. In fact, the data suggest that the opposite pattern may exist.” (p. 164)

Feedback Forms for Peer Assessment in Groups


Many faculty incorporate a peer-assessment component in team projects. Because faculty aren’t present when the groups interact and therefore don’t know who’s doing what in the group, they let students provide feedback on the contributions of their group-mates. In addition to giving the teacher accurate information on which to base individual grades, the process gives students…
