The study
Who took part
1,890 students in 15 rural middle schools in the Pacific Northwest, USA, followed from 7th to 8th grade. About half were girls and about three in four were White. 7 schools (875 students) got the lessons and 8 schools (1,015 students) waited.
What they did
Over two school years, trained teachers ran regular lessons where students worked in mixed groups of 2 to 4. Each student had a role. The group made one shared product or earned a group reward. Each student was also checked on their own part. After each lesson, students named something good each group member had done. The paper doesn't say how many lessons there were.
What happened
Students rated how hard they tried in class. This dropped over the two years in both groups, but it dropped less in schools with teamwork lessons. It was the same in both groups at the start and higher in the teamwork schools at the end.
What the study found
