PENGARUH MODEL DISCOVERY LEARNING BERBANTUAN EDUCAPLAY TERHADAP KEMAMPUAN PEMAHAMAN MATEMATIS MURID KELAS II SEKOLAH DASAR

Abstract

Abstract

This study aims to examine the effect of the Discovery Learning model assisted by Educaplay on the mathematical comprehension ability of second-grade students at SDN Cibodas 02, Solokanjeruk District, Bandung Regency. Mathematical comprehension ability is a fundamental competence in mathematics learning encompassing translation, interpretation, and extrapolation. A quasi-experimental method with a nonequivalent control group design was employed, involving 28 students from Class IIA (experimental) and 30 from Class IIB (control), totaling N = 58 students. The instrument consisted of 10 essay items on whole number multiplication with Cronbach's Alpha reliability = 0.741. Data were collected through pretest and posttest and analyzed using Independent Samples t-Test following Shapiro-Wilk normality and Levene homogeneity tests. Results showed the experimental class posttest mean (86.18) was significantly higher than the control class (81.87), with t = 2.706; df = 56; p = 0.009 < 0.05; and 95% CI [1.120–7.504]. Effect size measured by Cohen's d = 0.711 indicated a large effect (Coe, 2002). The Discovery Learning model assisted by Educaplay significantly influences mathematical comprehension ability of second-grade elementary students.
