The Effects of Collaborative Testing



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.

Why let students work on exams collaboratively? There are a number of reasons, most of which have been explored empirically. When students discuss questions and possible answers, they intensely engage with the content, which increases the learning potential of an exam experience. The activity develops cooperation and communication skills. But the reason most often given is that working with other students decreases exam anxiety, particularly for those students whose levels of anxiety compromise their ability to perform on exams.

When asked why they don’t use collaborative testing, most faculty report being afraid that students who have not prepared for the exam may inappropriately benefit from the knowledge of students who have studied. Grades should be measures of individual learning.

Based on a review of the literature on collaborative tests, these authors decided to explore four questions in their study: 1) How does collaborative testing affect test scores? 2) Is anxiety related to the effectiveness of collaborative testing? 3) Which students benefit from collaborative testing? and 4) How does the quality of interaction within the groups affect test performance? (p. 165)

The study included some unique design features. To deal with the potential problem of students coming to the exam unprepared and thinking the group would pull them through, students were told to prepare for the exam as if they were taking it individually. Those who would be taking the exam collaboratively would be randomly selected at the beginning of the period. On test days, those selected to take the exam collaboratively were moved to another room. Their group interactions were observed by a proctor who evaluated the quantity of interaction, the level of enthusiasm, and the degree of give-and-take displayed by the participants. (p. 166) The groups did not have to agree on answers, although they could change their answers based on discussions that occurred within the group. Tests were still submitted and graded individually.

As for how the collaboration affected test scores, the results were positive. “Collaborative testing was more successful for a significant majority of students than was traditional, individual testing, although the advantage (3.83%) was smaller than found in some previous studies.” (p. 172) Based on standardized measures of test anxiety, “students with higher initial test anxiety scores were most likely to benefit from the collaborative testing procedure and to show a decrease in test anxiety when taking tests collaboratively.” (p. 172) And finally, “high interaction scores, both proctor and student-rated, were related to better performance under the collaborative condition.” (p. 172)

Consistent in the research on collaborative testing mechanisms is the favorable response they generate from students. Students regularly report enjoying the experience and indicate they would choose it in the future, if given the opportunity. In this study, students said the testing mechanism was beneficial because it helped them develop good working relationships with classmates and helped them remember material they had forgotten. There were students in this study who did perform better on the tests they took individually, and a third of those students thought they did better on the individual exams because they found the discussions with other students confusing.

The researchers conclude that collaborative testing is a “worthwhile technique.” “For, even if overall test performance is not greatly improved by collaborative testing, the positive experiences of increased camaraderie and anxiety reduction it engenders could constitute substantial long-term benefits in the form of increased confidence, motivation, and willingness to continue one’s education.” (p. 173)

  1. This report begs an important question – what is the purpose of exams? The authors list a number of percieved benefits of collaborative testing such as relationship building, increased camaraderie and decreased anxieity. While we want students to have these benefits, this is not the purpose of exams. We test students to evaluate their knowledge. We should not shy away from holding students to a standard where they have to demonstrate knowledge without a colleague reminding them of material they have forgotten.

    • I suggest a better question is "Are traditional exams the best way to measure student learning?" By presuming higher education must include exams and that the purpose of exams is solely to measure individual learning, we lose the opportunity to consider other options. My goals in offering a collaborative exam process (but individual exam answers) are to reinforce the type of collaboration students will be expected to do in their profession; to expose students to others' approaches to critical thinking; to extend the learning portion of the course right through the final exam; AND to measure individual learning. The fact that the students actually enjoy the exam process (while labeling the exam "very hard") is just a side benefit!

    • I would say that exams function not only to test knowledge, but as a way of checking in with students to make sure they are learning. Gaining an understanding of a subject is more important than being able to regurgitate facts. If collaborative testing improves students overall understanding of a subject, then it's definitely worthwhile. And furthermore what real world situation would force you to recall information without being able to ask a colleague or check a reference?

  2. This report is timely. It's time that faculty move from a teacher-centered approach of teaching to a learner-centered approach. We as instructors need to explore our teaching style, and use some of the suggested nontraditional teaching strategies in the classroom. I'm reminded of the report such as the "Nation at Risk" that argued about educators being remiss in their duties and that they are doing a terrible job of educating people.
