PENINGKATAN KEMAMPUAN PEMECAHAN MASALAH DAN KOMUNIKASI MATEMATIS SISWA SEKOLAH MENENGAH PERTAMA MELALUI MODEL PEMBELAJARAN KOOPERATIF TIPE THINK-PAIR-SHARE (TPS)

Problem solving skills and communication skills is one of the mathematical achievement of the curriculum that must be owned by students in learning mathematics. For that, it needs the right learning model in improving communication skills and mathematical problem solvi ng of students, one model that can improve this ability is a cooperative mode l of Think-Pair-Share. The aim of this research is to examine differences in mathe matical problem solving skills and communication skills among students who obtain mathematical models of cooperative learning Think-Pair-Share and students who receive conventional learning. This research is an experimental study wi th the study design pre-test post-test control group design. With a population o f all eighth grade students of MTsN Darul Ulum Banda Aceh by taking samples of the two classes of experimental class and control class through purpos ive sampling of four parallel classes available. The data was collected using a t est instrument that tests problem solving skills and test students' mathematical comm unication skills. To see the difference in the ability of students between class es and grade control experiment used the t-test at significance level 0.05. Of the data and results of statistical tests were analyzed with SPSS 16.0 For Windows and Micros oft Excel 2007 to interpret the mathematical problem solving skills and communi cation skills of the students' mathematical model of cooperative learning with Thi nk-Pair-Share, Overall cooperative models use Think - Pair - Share can imp rove mathematical problem solving and mathematical communication skills of st udents.
