PEMBELAJARAN KOOPERATIF TIPE THINK-PAIR-SHARE DENGAN MENGGUNAKAN CATATAN KECIL UNTUK MENINGKATKAN KEMAMPUAN PENALARAN MATEMATIS SISWA SEKOLAH MENENGAH PERTAMA

Abstract

This research is motivatedby the low ability of students' mathematical reasoning, so the need for alternative learning that can improve students' mathematical reasoning ability is urgent. One of the type of cooperative learning which is Think-Pair-Share by using “cakil” is used in this research. This study aims to determine: (1) Whether the improvement of students' mathematical reasoning abilities that get Think-Pair-Share learning using “cakil” is better than students who get conventional learning; (2) Whether the improvement of students' mathematical reasoning abilities (group of high, medium, and low score) that get Think-Pair- Share learning using “cakil” is better than students who get conventional learning; (3) What is the student's attitude toward mathematics learning using “cakil” in Think-Pair-Share learning model. This research was conducted at SMPN 17 Kota Serang. The research method used is quasi experiment with Non- Equivalent Control Group Design. The sampling technique used is Purposive Sampling, because the sample is determined by the school. The results showed: (1) The improvement of students' mathematical reasoning abilities that get Think-Pair-Share learning using “cakil” is better than students who get conventional learning with tscore = 8.30 and ttable = 1.66; (2) The improvement of students' mathematical reasoning abilities (group of high, medium, and low score) that get Think-Pair-Share learning using “cakil” is better than students who get conventional learning with tscore = 21.55 and ttable = 1.75 (high group), tscore = 13.99 and ttable = 1.67 (medium group) and tscore = 17,06 and ttable = 1,94 (low group); (3) The result of questionnaire analysis which is filled by experimental class, it is found that attitude toward Think-Pair- Share learning using “cakil” is in strong criteria with average of 73,05%.
