Cooperative Learning With TSTS Type That Assisted of GMS To Improve Mathematical Communication Skills

Abstrak Penelitian ini bertujuan untuk mendeskripsikan penerapan pembelajaran kooperatif tipe TSTS (Two Stay Two Stray) berbantuan GPS (Geometri mapping study) terhadap kemampuan komunikasi matematis siswa. Penelitia ini dilakukan di kelas VII MTs.Ma’arif Ambulu. Jenis penelitian yang digunakan adalah penelitian tindakan kelas (PTK). Prosedur penelitian yang digunakan mengadopsi teori Kurt Lewin dengan 2 siklus dimana dalam satu siklus terdiri dari empat langkah yaitu perencanaan, tindakan, observasi dan refleksi. Hasil tes siklus I yang telah dilaksanakan diperoleh persentase sebesar 66% dan persentase hasil tes siklus II sebesar 90% dengan nilai minimal  berdasarkan KKM yang disesuaikan dengan indikator kemampuan komunikasi matematis secara tertulis. Hal terebut menunjukkan bahwa kemampuan komunikasi matematis siswa mengalami peningkatan dengan diterapkannya model pembelajaran kooperatif tipe two stay two stray berbantuan geometri mapping study.Kata kunci: TSTS, GPS, kemampuan komunikasi matematis Abstrack The purpose of the research is to describe the application of cooperative learning typeTSTS (Two Stay Two Stray) that assisted of GMS (Geometry Mapping Study) to improve students' mathematical communication skills. This research was conducted in class VII of MTs.Ma'arif Ambulu. This type of research is classroom action research (CAR). The research procedure adopted Kurt Lewin's theory with 2 cycles where in one cycle consisted of four steps namely planning, action, observation and reflection. The results of the first cycle test that has been carried out obtained a percentage of 66% and the percentage of the results of the second cycle test by 90% with a minimum value based on KKM adjusted to indicators of mathematical communication skills in writing. It shows that the students' mathematical communication skills have improved with the application of the two stay two stray cooperative learning tipe that assisted by the geometry of study mapping.Keywords: TSTS, GPS, mathematical communiation skills
