Although still not at all that widely used, there’s long-standing interest in letting students work together on quizzes or exams. Upon first hearing about the approach, teachers’ initial response is almost always negative. Here are the most common objections.
- Grades are measures of individual mastery of material. With a group exam or quiz, some students may get a better grade than they’ve earned. Group grades do not measure individual learning.
- A group can settle on wrong answers and thereby lower the score of the single bright student in the group who knows the right answer.
- Group exams and quizzes make it too easy for students. They don’t have to think for themselves but can rely on others in the group to do the thinking for them.
- It’s cheating. Students are getting answers they don’t know from other students. They’re consulting another source rather than putting in the work and developing their own knowledge.
- Certifying exams (various professional exams such as those in nursing, accounting, the MCAT and GRE, for example) are not group exams. Group quizzes and exams do not prepare students for these all-important assessments.
- Group exams and quizzes reduce test anxiety. Pretty much across the board, students report that anticipating and participating in group exams and quizzes makes them feel less anxious. And for students with exam anxiety, that can be a significant benefit.
- Collaborative quizzes and exams show students that they can learn from each other. Many students arrive in courses believing the only person they can learn from is the teacher. But as they talk about test questions, share answer justifications, discuss what content the answer requires, they get to experience what it’s like to learn from peers.
- Group quizzes and exams provide immediate feedback. Students don’t have to wait to get the exam back. They get a good indication from those in the group why the answer is or is not correct.
- Working together on test questions teaches students how to identify credible arguments and sources. Given the opportunity to change answers based on what someone else says directly confronts students with the tough issues of who to believe and when to trust their own judgment.
- Collaborative quizzes and exams model how problem solving in professional contexts usually occurs. Professionals collaborate, they have access to resources, they can contact experts, they argue options, and evaluate possible answers. Collaborative testing gives students the opportunity to see how and why that results in better decision making.
- Group quizzes and exams can improve exam scores and sometimes, but not always, content retention. The improvement in scores is an expected outcome of collaboration, but the improvement is also present when students collaborate on exam questions and then answer questions that deal with the same content on a subsequent exam taken individually. Effects of collaboration on retention are mixed.
