Students' Understanding of Mathematical Concepts Using Manipulative Learning Media in Elementary Schools

Abstract

This study aims to analyze students' understanding of mathematical concepts in the material of addition and subtraction of integers by using manipulative media in the form of colored paperboard designed into rectangular shapes. This research was conducted in class IV SDN 02 Koto Tangah. The subjects in this study are class IVB students with the total number of 25 students. The instrument used in this research was a subjective test that had fulfilled mathematical concept indicators and test indicators. Data analysis was carried out by using the N-Gain formula developed by Meltzer (2002 and then was interpreted based on the classification of the N-Gain index from Hake (1999). The results of this study reveal that mathematics learning by using manipulative media in the form of rectangular shape designed paperboard can improve students' understanding of mathematical concepts in the material of addition and subtraction of integers.
