Group Exams and Quizzes: Design Options to Consider

By:

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.

On the other hand, those who do allow group collaboration on exams and quizzes may respond to the objections with a corresponding set of set of advantages associated with their use.

  • 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.

An Interesting Group Testing Option

By:

Is this situation at all like what you’re experiencing? Class sizes are steadily increasing, students need more opportunities to practice critical thinking skills, and you need to keep the amount of time devoted to grading under control. That was the situation facing a group of molecular biology and biochemistry professors teaching an advanced recombinant DNA course. They designed an interesting assessment alternative that addressed what they were experiencing.

Does Discussion Make a Difference?

By:

Here’s the scenario: Students are taking a chemical thermodynamics course. The instructor solicits clicker responses to a conceptually based multiple-choice question. Students answer individually, write a brief explanation in support of their answer, and indicate how confident they are that their answer is correct. They are then encouraged to discuss their answers with two or three (self-selected) other students. After that discussion, they have the opportunity to change their answer if they wish, write another explanation for the answer, and once again indicate their degree of confidence in their answer. Do you think that discussion would make a difference—particularly, would it make a difference in their understanding of the concept?

Discussion Made a Difference in Student Learning

By:

The evidence that students benefit when they talk about course content keeps mounting. In the study highlighted below, students in two sections of an introductory zoology course were learning about the physiological mechanisms of RU-486 and about emergency contraception medication. They learned about the topic in three 50-minute lecture periods. Students in both sections were given supplementary reading that reinforced the content, and they were encouraged to ask questions and discuss the content during lab. In addition, students in the experimental bioethics section read and discussed essays that addressed the social, ethical, and legal issues associated with use of emergency contraception. Students in the experimental section then discussed these readings. They managed the discussion, asking questions and raising the issues they wanted to talk about. The instructor intervened only when there was confusion about the content or when prompting and follow-up were needed to advance the discussion.

The Effects of Collaborative Testing

By:

Although letting students work together on exam questions is still not a common instructional practice, it has been used more than might be expected and in a variety of ways. Sometimes students work together in groups; other times with a partner. Sometimes those groups are assembled by the instructor and sometimes students are allowed to select their partners or group members. Sometimes the groups share multiple exam experiences; other times they work collaboratively only once. Sometimes the group submits one exam with everyone in the group receiving that grade; other times students may talk about exam questions and answers but submit exams individually.

Group Exams and Quizzes: The Benefits of Student Collaboration

By:

Have you ever used any sort of group testing activity? The approach is not without benefits. Most students find exams enormously stressful and abundant research documents that high levels of test anxiety can compromise performance. Said more bluntly, students can know the information, but be so anxious they can’t summon it for the exam. Letting students work together on test questions reduces that anxiety considerably. It could be a case of “misery loves company” or the “two heads are better than one” scenario.
