Work in a Group? Succeed More

I know my son really enjoys it when a teacher assigns a project as a group.  It surprises me a little that so many projects in high school seem to be done in a group (when I was in high school, it was always on your own).  But a new study says that, taking turns, and working with friends, may lead to better grades.

I wonder if that works in the workplace?  More on that later.

Dreaded by some, loved by others, group projects typically aim to build teamwork and accountability while students learn about a topic. But depending on the assignment and the structure of the groups, a project can turn out to be a source of great frustration — for instructor and students alike — or the highlight of the school year.

Now a University of Washington-led study of college students has found that the social dynamics of a group, such as whether one person dominates the conversation or whether students work with a friend, affect academic performance. Put simply, the more comfortable students are, the better they do, which yields benefits beyond the classroom.

"They learn more," explains Elli Theobald, a postdoctoral researcher in the Department of Biology and the lead author on the study, published July 20 in PLOS ONE. "Employers are rating group work as the most important attribute in new recruits and new hires. If students are able to demonstrate that they have worked successfully in groups, it would seem that they should be more likely to land the job."

Theobald is part of the UW's Biology Education Research Group lab, formed by several faculty members in the Department of Biology about a decade ago to research how to most effectively teach biology to undergraduates.

Over the years, research spanning K-12 through post-secondary education has pointed to the value of group work in fostering collaborative skills and in cementing learning through interaction. In the sciences, labs are a common, though not the only, form of group work, Theobald says. As with many disciplines, STEM fields lend themselves to readings, worksheets and other activities that can be completed by multiple people working together.

For this study, researchers compared survey responses and test scores stemming from two different project styles — single-group and "jigsaw."  In a single-group activity, student groups completed a worksheet together, relying on their notes and textbooks. In a jigsaw, student groups were assigned specific sections of the worksheet; students then were shuffled to new groups in which each person in the group had completed a different section of the worksheet and could teach their new group mates what they had learned. Students took an eight-question test after each assignment.

The study found that students who reported a "dominator" in the group fared worse on the tests than those who didn't express that concern. It also found that students who said they were comfortable in their group performed better than those who said they were less comfortable.

The jigsaw activity appeared to result in more collaboration: Students were 67 percent less likely to report a dominator in jigsaws than in single-group activities. "This suggests that jigsaw activities with intentional structure more effectively promote equity than group activities with less intentional structure," researchers write.

Interestingly, international and Asian American students were six times as likely to report a dominator than white American students. "Not all students experience group work the same way," researchers write in the study. "If one student dominates a conversation, it can be particularly jarring to students from cultural backgrounds that place more emphasis on introspection and thinking on one's own as opposed to a direct relationship between talking as a way to work through ideas."

So would this work in the workplace?  

Groups of three, four, or five perform better on complex problem-solving than the best of an equivalent number of individuals, according to the American Psychological Association, no matter where the groups are located..

Though the data was collected from college students, the findings translate to other settings, Theobald notes. She pointed to a study Google conducted to determine what made groups successful — establishing group routines and expectations ("norms") and adding a brief window at the beginning of work time for casual talk.
