Promoting Collaborative Classrooms: The Impacts of Interdependent Cooperative Learning on Undergraduate Interactions and Achievement.

Collaboration is an important career skill and vital to student understanding of the social aspects of science, but less is known about relationships among collaborative-learning strategies, classroom climate, and student learning. We sought to increase the collaborative character of introductory undergraduate laboratory classrooms by analyzing a 9-week intervention in 10 classrooms ( n = 251) that participated in cooperative-learning modules (promoting interdependence via a modified jigsaw technique). Students in an additional 10 classrooms ( n = 232) completed the same material in an unstructured format representative of common educational practice. Results showed that, when between-class variance was controlled for, intervention students did not score higher on weekly quizzes, but science interest and prior science experience had a reduced relationship to quiz performance in intervention classrooms. Also, intervention classrooms showed increased collaborative engagement at both whole-class and individual levels (24 students at three time points), but the intervention was only one of several factors found to account for late-intervention classroom collaborative engagement (prosocial behavior and discussion practices). Taken together, findings suggest that integrating interdependence-based tasks may foster collaborative engagement at both small-group and whole-classroom levels, but by itself may not be enough to promote increased student achievement.
