Peer evaluation can be a powerful teaching and learning strategy in some classroom situations. It can encourage students to take a more active role in coursework, and it can provide opportunities for students to make useful and thoughtful comments or suggestions through collaboration and patience.
Instructors can require students to formally evaluate their own work and the work of fellow students on specified individual or group projects, papers, or presentations. When implementing peer evaluation, both instructors and students must understand and agree upon the elements to be evaluated, and what tools will be used. Rubrics, which are grading tools created to communicate the expectations of assignments, can provide a good starting point for developing peer evaluation items. Instructors can provide students with a clear rubric to follow, or students can be asked to create their own ground rules and rubrics for the peer evaluation of a specific project. You can refer to the article “Using Rubrics” in the CITES Newsletter for more information and helpful resource links.
In some cases, the instructor may choose to factor the results of peer evaluations into each student’s final grade, but this would depend on the objectives of the exercise and should be done with caution. Regardless of the grading factor, instructors using peer evaluation in group projects must:
- Communicate to the group that the group process, as well as the final project outcome, is important;
- Provide a mechanism for assessing student participation and involvement in the group assignment.
Benefits for student’s participation in peer evaluation of individual projects may include:
- Enhancing student focus on tasks that must be completed;
- Helping students understand the criteria used to determine their grades;
- Providing students practical insight on how their peers approach the same assignment;
- Providing students with the experience of receiving and giving feedback;
- Keeping students engaged during another student’s presentation.
The benefits of using peer evaluation in group projects may include:
- Providing evidence to the group that the group process, as well as the final project outcome, is important;
- Encouraging students’ accountability to each other;
- Providing students with the experience of receiving and giving feedback;
- Providing students with feedback on how others perceive their interpersonal communication skills and contributions to a group team effort.
A frequent argument against peer evaluation is that students will not be objective in evaluating their classmates, either to enhance their own personal achievement or due to interpersonal relationships with individual classmates. Instructors must ensure that students fully understand that in a course setting, peer evaluation is a valuable strategy for learning and in obtaining feedback, but there will be set limits to incorporating peer evaluation results into student grades.
One way to introduce students to some of the benefits of peer evaluation of individual assignments can be achieved by having students evaluate examples of students’ work from previous years. This effectively eliminates the personal or interpersonal factors, and can help students to learn the expectations of an assignment by reviewing good and poor examples of what their peers previously accomplished. This may also help students become comfortable with the process of evaluating peers.
To increase the usefulness and validity of peer evaluation with current classmates, the process can be set up to be strictly anonymous. For individual paper assignments, anonymity can be implemented so that both the student whose paper is being evaluated and the evaluator remain anonymous. For individual presentations and group projects, the evaluator can be anonymous. The disadvantage of anonymity is that the evaluator cannot be held accountable for feedback that may be arbitrary or unfair. Therefore, you may wish to make a distinction between anonymity and confidentiality. Feedback can remain completely anonymous when provided by one student to another, but you as the instructor will have the confidential identity of each peer evaluator. If peer evaluation is set up using this combination of anonymity between students and confidentiality held by the instructor, all students must clearly understand that you as their instructor will hold each peer providing feedback accountable for their specific input.
Instructors frequently consider using peer evaluation as part of the process when students are required to complete assignments requiring group cooperation. As you have no doubt experienced, group projects are seldom a student favorite. Group projects can be challenging because they require a distribution of workload between group members and the efforts to complete tasks is not always equitable. Implementing and sharing the results of peer evaluation during the process of completing the project may be one way for students to address and remedy perceived inequities. Again, it is important to
- Create an evaluation rubric ahead of time;
- Decide on whether the feedback will be anonymous;
- Decide how, if at all, the peer evaluations will be counted in the student’s grade.
Instructors need to keep in mind that for group projects, it may also be important to devise a mechanism so that students will be able to respond to individual feedback –whether or not it is anonymously provided.
As previously stated, sound ground rules and well-designed rubrics are essential to the success of using peer evaluation in any specific classroom project. As with all instructional strategies, peer evaluation needs to be considered within the context of the learning objectives of the assignment and the most effective strategies for students to achieve those outcomes.
We invite you to contact CITES if you would like to brainstorm ways to incorporate peer evaluation into your class. Below we provide some examples of peer evaluation forms and links to other resources of use when you consider, or reconsider, using peer evaluation:
