Abstract

Physics teachers in Indonesia still face obstacles during learning, such as students who are less active and have difficulty in solving physics problems. The physics learning media used are also still not very interesting and are not based on authentic problem solving. Therefore, this study focuses on the development of PBL-based e-modules on work and energy to improve the physics problem-solving abilities of high school students. This research and development used the ADDIE design and was tested on 90 high school students in High School 1 Sumber Pucung Malang in the 2022/2023 academic year. The questionnaire instrument was used in the validation and practicality tests, while 5 physics problem-solving essay questions (a = 0.688) were used as the test measurement instrument. Descriptive statistical analysis, t-tests, and N-gain measurements were used in this study. The results of the validity test and practicality test indicated that the developed PBL-based physics e- module scored 92% and 73.93. The results of further analysis also found that the problem- solving abilities of experimental class students increased in the moderate category (g = 0.59) after using our PBL physics e-module. We conclude that the PBL-based physics e-module in this research and development is valid, practical, and effective enough to be used to improve students' problem-solving abilities.
