PENGARUH MODEL PROBLEM BASED LEARNING TERHADAP HASIL BELAJAR MATEMATIKA SISWA SD IT DAARUL ISTIQLAL

This study aims to determine the effect of the Problem-Based Learning (PBL) model on the mathematics learning outcomes of students at SD IT Daarul Istiqlal. The study employs a quantitative approach using a pretest-posttest control group design. The sample consists of fifth-grade students: class V-A (25 students) served as the experimental group, while class V-B (25 students) served as the control group. Data were collected using questionnaires to measure learning motivation and tests to assess learning outcomes. A pretest was administered before the implementation of the PBL model, followed by a posttest after its implementation. Data analysis involved both descriptive and inferential statistics. The results indicate an increase in the average learning outcome scores, rising from 60.82 (pretest) to 79.86 (posttest). As shown in Table 1, the average posttest score is higher than the pretest score. Normality tests yielded values ​​of 0.062 for the pretest and 0.073 for the posttest, indicating that the data follow a normal distribution. Hypothesis testing revealed a significance value (2-tailed) of 0.000 (p < 0.05) regarding the effect of the Problem-Based Learning model on student learning outcomes; therefore, the alternative hypothesis (Ha) is accepted, and the null hypothesis (Ho) is rejected. In conclusion, the implementation of the Problem-Based Learning model has a positive effect on the mathematics learning outcomes of fifth-grade students at SD IT Daarul Istiqlal.
