Abstract

Students often experience difficulties in understanding multiplication concepts, which served as the background of this study. This study aimed to examine changes in students’ problem-solving abilities following the implementation of the Problem Based Learning (PBL) model assisted by multiplication stick media among third-grade students at SDN Kramat Pela 09, South Jakarta. This study employed a quantitative approach using a one-group pretest–posttest design involving 32 students. The intervention was conducted over five learning sessions. Data were collected through essay tests, observations, and documentation. The data were analyzed using descriptive statistics, the Shapiro–Wilk normality test, and the Wilcoxon Signed Ranks Test. The results showed that the students’ mean score increased from 64.05 on the pretest to 93.23 on the posttest. The Wilcoxon test yielded an Asymp. Sig. (2-tailed) value of < 0.001, indicating a statistically significant difference between the pretest and posttest scores. These findings indicate an improvement in students’ problem-solving abilities following the implementation of the PBL model assisted by multiplication stick media. However, due to the one-group pretest–posttest design, causal claims should be interpreted with caution. Furthermore, the findings suggest that integrating the PBL model with concrete learning media may support students’ active engagement in mathematics learning and contribute to the development of problem-solving skills.
