PENINGKATAN KEMAMPUAN REPRESENTASI DAN KONEKSI MATEMATIK PESERTA DIDIK MELALUI MODEL PEMBELAJARAN KOOPERATIF TIPE GROUP INVESTIGATION (GI)

Abstract

This research aims to know the enhancement mathematical representation and connection ability of learners through cooperative learning model of the GI with scientific approach better than learners who use Discovery Learning model with scientific approach. Also there to knowing the self directed learning learners in learning mathematics through cooperative learning model of the GI with scientific approach. The population in this study were class VII SMPN 8 Tasikmalaya years lessons 2017/2018. The sample in this study is taken as much as two class based on simple random sampling. Selected class VII I as experiments class and class VII B as control class. Instruments used to collect data in this study such as test instruments of mathematical representation and connection ability as well as questionnaire self directed learning. This research method used is a experimental with non equivalent control group design that is part of quasi-experimental. Based on the data analysis and hypothesis testing as well as answering questions of research, the results showed that there the enhancement mathematical representation and connection ability of learners through cooperative learning model of the GI with scientific approach better then of learners through Discovery Learning model with scientific approach and self directed learning learners in learning mathematics through cooperative learning model of the GI with scientific approach included in the interpretations of good.
