PENERAPAN STRATEGI PEMBELAJARAN INKUIRI BERBANTUAN ALAT PERAGA “DULOK KUMISAN” DALAM MENINGKATKAN PEMAHAMAN MATEMATIS PESERTA DIDIK

Abstract

One of the basic competencies that must be mastered by the fifth grade students is a mathematical understanding of the volume of cubes and cuboids. Observations show that most of the fifth grade students at SDN Margahayu 08 in the 2018/2019 academic year demonstrate low mathematical understanding. This study aims to apply the inquiry learning strategy assisted by the "Dulok Kumisan", a teaching aid in improving mathematical understanding. The research method used is the quasi-experimental research design with nonequivalent control group design. The instruments used were description tests and observation sheets of learning implementation. The first hypothesis testing used the average difference test (data comes from normal and homogeneous distributions) while the second hypothesis was tested with the Mann Whitney U Test because normality is not met but comes from homogeneous variance. The results showed that the mathematical understanding of experimental group students who applied inquiry learning strategies assisted with the "Dulok Kumisan" teaching aid was better than that of the control class that used conventional learning methods. There was an improvement in mathematical understanding of the fifth grade students at SDN Margahayu 08 on cube and cuboid volume after the inquiry learning strategy was used. Thus, the inquiry learning strategy assisted by the "Dulok Kumisan" teaching aid can be applied to improve mathematical understanding.
