PEMBELAJARAN MATEMATIKA MODEL COOPERATIVE INTEGRATED READING AND COMPOSITION (CIRC) UNTUK MENINGKATKAN KEMAMPUAN KOMUNIKASI MATEMATIS MATERI SEGIEMPAT KELAS VII

Abstract

Students experience in learning mathematics, they stated that the completion of word problems is more difficult than non-story. This happens because they are required to be able to understand , plan for completion and make a solution of the problem. Completion of word problems requires mathematical communication skills of each student . Therefore , teachers must be able to stimulate the students to improve communication skills by planning and implementing mathematical learning according to their condition. One type of cooperative learning is the CIRC , which emphasizes the ability to read or understand the problems. This research is a quantitative study using experimental methods . The variable in this study is a mathematical communication skills as independent variables and mathematical learning model with the CIRC as the dependent variable . The data were obtained by using the test . The data were processed with one sample t-test and test Normalized Gain . The results showed that the average mathematical communication skills achieved by students is 76.71 . This value exceeds the specified KKM (KKM = 70) so as to achieve mastery learning. The results of test calculations mathematical communication skills improvement based on pre-test and post- test was 35.12 % , which means an increased interpretation capabilities including mathematical communication in the medium category . Based on the results obtained , it is known that the mathematical learning by using cooperative learning model CIRC can improve students' mathematical communication skills .
