Abstract

This study aims to measure the effectiveness of using the Problem-Based Learning (PBL) model assisted by interactive website-based learning media on the understanding of mathematical concepts, specifically basic multiplication and division. This quantitative study used a pre-experimental method with a One-Group Pretest-Posttest design. The research sample consisted of 30 third-grade students at SDN Karanganyar 2, drawn using a proportional Simple Random Sampling technique. Data collection was carried out through written test instruments in the form of multiple-choice and graded essay questions. Descriptive analysis results showed a spike in the students' average score from 53.83 in the pre-test to 85.67 in the post-test. Hypothesis testing using the Paired Sample t-test proved a highly significant difference with a Sig. (2-tailed) value < 0.001. Furthermore, the Normalized Gain (N-Gain) effectiveness test analysis resulted in an average score of 0.7003 (70.03%), which is in the high or quite effective category. It can be concluded that the integration of the PBL model driving the website media classically is proven effective in improving students' numeracy literacy and understanding of mathematical concepts without being hindered by the physical limitations of the school.
