THE EFFECT OF THE JIGSAW COOPERATIVE LEARNING MODEL ON STUDENTS' MATHEMATICAL COMMUNICATION SKILLS

This research aims to know whether the Jigsaw Cooperative Learning model affects students' mathematical communication skills and to know how effective is the Jigsaw-type cooperative learning model on students. mathematical communication skills. The design of this research is quasi-experimental. The sample of this research is students in class IX-E and students in class IX-F. The results of this research are: (1) The Jigsaw Cooperative Learning Model has a positive effect on student's mathematical communication skills. This can be seen from the significance value for the two-tailed test is observed as 0.031 < 0.05. Then, H0 is rejected and Ha is accepted. (2) The affectiveness of the Jigsaw Cooperative Learning Model is taken from the N-Gain result, which is 0.16. It can be concluded that the effectiveness of the jigsaw cooperative learning model on students' mathematical communication skills is in the category.
