Abstract
This study aims to investigate the impact of the jigsaw cooperative model and the case method on undergraduate students^ understanding of physics concepts and their communication skills. This study used a quasi-experimental method with a pretest-posttest non-equivalent control group design to explore information on understanding of physics concepts. Understanding of physics concepts was measured using a reasoned multiple-choice test. While communication skills were measured using a self-assessment sheet. The sample of this study involved 40 undergraduate students who were divided into an experimental class and a control class. The results showed that the pretest data on understanding of physics concepts in both classes were not significantly different. However, the posttest data on understanding of physics concepts were significantly different with the N-Gain score of the experimental class (0.46) being higher than the N-Gain of the control class (0.29). Based on the results of the self-assessment, the average communication skills score of undergraduate students in the experimental class (76.29) was also higher than that of the control class (68.71). These results indicate that the implementation of the jigsaw cooperative model and the case study method can improve understanding of physics concepts and develop communication skills of undergraduate students.
