Abstract

This study is a true experimental design study using a 2x2 factorial design. The purpose of the study is to: find out whether or not the application of the Problem Based Learning model and learning interest has an effect on the results of physics problem solving abilities of class XI MIPA, and to diagram the interaction of the learning model and learning interest on the results of physics problem solving abilities. The research data were obtained by providing a learning interest questionnaire sheet to students before being taught using the learning model in the study, and for the Problem Solving ability test results were carried out after students were taught using the learning model in the study. The data analysis technique used was analysis of variance (ANOVA). Based on the results of the inferential analysis obtained: F count (26.57) > F table 4, it can be concluded that there is a significant difference between students who are taught using the Problem based learning model and students who are taught using the discovery learning model; F count (0.53) < F table 4, it can be concluded that there is no interaction between the learning model and learning interest on the results of students' Problem Solving abilities.

Abstract

This study aims to analyze the content validity of the developed Science Process Skills (SPS)-based physics instructional materials; analyze the responses of educational practitioners regarding the quality and practicality of the materials; and analyze the effect of the developed SPS-based physics instructional materials. The research employed the Research and Development (R&D) method with the 4D model (Define, Design, Develop, and Disseminate). The developed product was validated by three experts, its practicality was assessed by ten physics teachers, and it was tested on 36 tenth-grade students. The instruments used in this study included a validation sheet for the instructional materials, a practitioner response questionnaire, and a validated critical thinking skills test for students. The results showed that the SPS-based physics instructional materials were validated using Aiken’s V index, with an average score of 0.81 for content feasibility, 0.82 for presentation, 0.82 for language, and 0.81 for graphical aspects. The overall average score was 0.82. The hypothesis testing showed that tcount = 8.006 ≥ ttable = 1.994, indicating a significant difference in critical thinking ability between students taught using the SPS-based physics materials and those taught using conventional materials. Based on these findings, the developed SPS-based physics instructional materials are valid according to experts, practical based on teachers’ assessments, positively received, and effective in improving students’ critical thinking skills, thus feasible for implementation in physics learning as a supportive medium to enhance students’ critical thinking abilities.
