PENERAPAN MODEL KOOPERATIF TIPE JIGSAW II UNTUK MENINGKATKAN KEMAMPUAN KOMUNIKASI MATEMATIS DAN SELF-ESTEEM PESERTA DIDIK SMP

Abstract

The problem behind this research is the low mathematical communication skills of students in learning mathematics. One alternative learning that can be applied to improve students' mathematical communication skills is the Jigsaw II Cooperative Model. This study aims to compare the improvement of mathematical communication skills of students who learn to use the Jigsaw II Cooperative Model with those who learn to use the Problem Base Learning Model and to determine the effect of the Jigsaw II Cooperative Model on the Self-Esteem of students. The method used in this study is quasi-experiment with the Nonequivalent Pretest-Postest Control Group Design design. The study was conducted in one of the junior high schools in the city of Bandung. The population in the study were all students of class VII with the sample, namely students of class VII-A as the experimental class and class VII-B as the control class. The instrument used was a mathematical communication ability test, a Self-Esteem questionnaire, and an observation sheet. Based on the analysis of the results of the mathematical communication ability test, it can be concluded that the improvement of mathematical communication skills of students who learn using the Jigsaw II Cooperative Model is better than students who learn using the Problem Base Learning Model and the Jigsaw II Cooperative Model affect the Self-Esteem ability learners.
