Abstract

This study aimed to find out the effectiveness of cooperative learning model of TPS type in terms of students’ mathematical communication skills. The population of this study was all seventh grade students of SMP Negeri 19 Bandarlampung in even semester academic year of 2018/2019 as many as 319 students. The research samples were students of class VII-E as many as 32 students and VII-J as many as 32 students who were selected through cluster random sampling technique. The design used was the randomized pretest-posttest control group design. The research data was the score of mathematical communication skills that obtained through a essay test. The results of hypothesis testing using the t -test and proportion test concluded that the cooperative learning model of TPS type was effective in terms of students' mathematical communication skills.
