Strategi Scaffolding Berbasis Multirepresentasi untuk Mengatasi Kesulitan Pemahaman Konseptual Siswa dalam Operasi Pecahan di SMP

Abstract

This research aims to overcome the students' difficulties of conceptual understanding of mathematics by using scaffolding strategy based-multi representation in addition and substraction of fractions at seventh grade students of SMPN 13 school year 2014/2015. This research method used is descriptive analysis which is oriented on students problem solving in learning addition and substraction of fractions. The subjects of this research are 3 students at grade VII F of SMPN 13 Pontianak that represent in each ZPD (high, medium, low).
