PENINGKATAN KEMAMPUAN REPRESENTASI MATEMATIS SISWA MELALUI MODEL PEMBELAJARAN SCAFFOLDING

Abstract

The purpose of this study is to find out the students' mathematical representation ability by means of the scaffolding learning model. This study used a quasi-experiment with nonequivalent control group design as the research method The data analysis technique was the parametric test t 'test. the population was the VIII A to VIII D students of SMP Negeri 3 Ciamis, Indonesia. The samples were taken using the cluster random sampling technique. 30 students of the VIII B were the experimental class and 30 students of the VIII C were the control class. The main instrument used was the test instrument which is an essay of mathematical representation ability test. The test was about cubes and blocks. The results showed that there were differences in increasing mathematical representation ability between students who taught by scaffolding model and students who taught by direct learning (Direct Instruction). The recommendation of this study is that the discussion part needs to be more effective because it was less conducive.
