Abstract

Mathematical problem-solving ability is an essential competency in mathematics learning, yet students still experience difficulties in understanding problems, determining strategies, and evaluating solutions. Although Argument-Driven Inquiry (ADI) and Realistic Mathematics Education (RME) have been widely applied in mathematics learning, their integration to improve mathematical problem-solving ability remains relatively limited. Therefore, this study aims to analyze the effect of the RME-based ADI learning model on students' mathematical problem-solving abilities in Systems of Linear Equations in Three Variables (SPLTV). This quantitative study employed a quasi-experimental Pretest-Posttest Control Group Design involving 72 Grade X students at SMA Negeri 2 Percut Sei Tuan. Data were collected using an essay test and analyzed using descriptive statistics, the Shapiro–Wilk test, Levene's test, independent-samples t-test, and Cohen's d. The experimental class obtained a higher mean post-test score (85.24) than the control class (67.56), with p < 0.001 and an effect size of 3.548, categorized as a huge effect. These findings indicate that the RME-based ADI model can be an effective alternative for improving students' mathematical problem-solving abilities.

Abstract

This study aimed to examine the effect of the Cooperative Learning model of the Group Investigation (GI) type assisted by the Make a Match game on students’ mathematical problem-solving ability in statistics. The study employed a quantitative approach with a quasi-experimental method and a Nonequivalent Control Group Design. The sample consisted of 53 eighth-grade students, with 27 students in the experimental group and 26 students in the control group. Data were collected using an essay test of mathematical problem-solving ability that met the validity and reliability requirements (r₁₁ = 0.930). The data were analyzed using descriptive statistics, the Lilliefors normality test, the homogeneity test, an independent-samples t-test, and Cohen’s d effect size. The results showed that the mean posttest score of the experimental class was 83.78, compared with 78.96 for the control class. The t-test result showed a t-count of 2.190, which was greater than the t-table value of 2.008 at α = 0.05, indicating a significant difference between the two groups. The Cohen’s d value of 0.60 indicated a medium effect. Therefore, the Cooperative Learning model of the Group Investigation type assisted by the Make a Match game had a significant and practically meaningful effect on students’ mathematical problem-solving ability in statistics.
