Abstract

This study aimed to determine the effect of the multimodal-assisted Problem-Based Learning (PBL) model on students’ problem-solving abilities in the topic of work and energy. A quasi-experimental method with a nonequivalent control group design was employed. The sample consisted of 33 students in the experimental class and 33 students in the control class at SMAN 1 Gunungsari. Data were collected using a validated and reliable problem-solving ability test and analyzed using t-test and N-Gain analysis. The results showed that the average pretest scores of the experimental and control classes were 34.818 and 31.758, respectively, while the average posttest scores increased to 82.697 and 76.697. The experimental class achieved an average N-Gain score of 0.733 (high category), whereas the control class obtained 0.644 (medium category). The findings indicate that the multimodal-assisted PBL model has a significant positive effect on students’ problem-solving abilities. Therefore, this learning model can be used as an effective alternative to improve students’ problem-solving abilities in physics learning, particularly on work and energy topics.
