Abstract

This study aimed to examine the effect of the Problem-Based Learning (PBL) model assisted by geoboard media on the mathematics learning outcomes of fourth-grade students at MIS Fajar Shiddiq during the 2025/2026 academic year. A quantitative approach with a quasi-experimental method and a non-equivalent control group design was employed. The sample consisted of 67 students selected through purposive sampling, comprising 34 students in Class IV-A as the experimental group and 33 students in Class IV-B as the control group. Data were collected through multiple-choice tests and observations. The results showed that the experimental group's mean score increased from 46.62 on the pretest to 70.88 on the posttest. Meanwhile, the control group's mean score increased from 48.18 to 65.30. Hypothesis testing yielded a t-value of 3.601, exceeding the critical t-value of 1.996 at the 0.05 significance level. These findings indicate a statistically significant difference in mathematics learning outcomes between the experimental and control groups. Therefore, PBL assisted by geoboard media had a significant effect on the mathematics learning outcomes of fourth-grade students at MIS Fajar Shiddiq. The findings suggest that integrating problem-based learning with geoboard media may support mathematics learning in elementary schools.
