Penerapan Pembelajaran Kooperatif Berbantuan Alternative Solutions Worksheet untuk Meningkatkan Kemampuan Pemecahan Masalah Matematis Siswa

Abstract

This study aims to increase mathematical problem solving ability of students in rectangular of matter in class VII MTs. Darul Amin Pontianak. The method used is Quasi-Experimental Design with the study design Posttest Only Control Group Design. The study sample is 44 students. The result of the t test obtained value the Sig. (2-tailed) = 0.006 <α = 0.05 which means that on average there is a difference between the mathematical problem solving ability of students who were given a cooperative learning aided alternative solutions worksheet (ASW) and students who were given a direct learning aided ASW. The result of normalized gain calculations, obtained a value of 0,59, which means there is an increased problem solving ability of student after application cooperative learning aided ASW . The result of Size Effect calculations, obtained a value of 2,89, which means using the cooperative learning aided ASW provide the highest contribution to the mathematical problem solving ability of student
