Abstract

This research and development study aimed to produce learning materials based on a generative model assisted by PhET simulations to enhance students' critical thinking skills. The 4D development model (Define, Design, Develop, Disseminate) was employed. The developed products included a syllabus, lesson plans (RPP), teaching materials, student worksheets (LKPD), and a critical thinking skills assessment instrument. The validity of the products was evaluated by six validators using a Likert scale, practicality was assessed through student response sheets, and effectiveness was measured by the improvement in pretest-posttest scores using the N-Gain test. The results showed that the developed learning materials were highly valid (89.14%) and reliable (94.00%) based on validator assessments, and practical (72%) based on student responses. However, the improvement in students' critical thinking skills was moderate (N-Gain 0.43), indicating less than optimal effectiveness of the materials.

Abstract

This study aims to evaluate the effectiveness and influence of a PhET-assisted generative learning model on improving students' understanding of physics concepts. This research employed a quantitative approach utilizing a one-group pretest-posttest design. Data were collected using a concept understanding test and analyzed using the Normalized Gain (N-Gain) score to determine effectiveness, as well as a paired sample t-test to assess statistical significance. The results yielded an N-Gain value of 0.40, categorizing the improvement as moderate. Furthermore, the t-test analysis revealed a significance value of 0.000 (p < 0.05), leading to the acceptance of the alternative hypothesis. Consequently, it can be concluded that while the PhET-assisted generative learning model significantly influences students' concept understanding, its implementation is currently classified as less effective, suggesting the need for further optimization.
