Through the use of online graphic design platform CANVA and waste management programs, this study seeks to create electronic student worksheets to enhance students environmental awareness using Model Problem Based Learning on alternative energy. The ASSURE model, which includes the development stage, is applied uses the Research and Development methodology. At SMA Negeri 8 Padang, observations the school environment and needs analysis involving 1 physics teacher and 28 students were conducted as part of the analysis stage. Based on these initial observations, it was found that students' environmental awareness was still low. In addition, students understanding of alternative energy was quite limited because digital teaching materials had not been fully utilized. Based on these identified problems, digital student worksheets on waste management programs were created to boost environmental awareness using the Model PBL. By using the Kappa Moment, the product feasibility validity test test conducted by three physics lecturers confirmed the content, language, presentation, and graphics were valid. Revisions were made based on their feedback. Based on results, it was shown the electronic student worksheet on alternative energy based on the waste management program "Nabuang Sarok" is appropriate to use, especially in the independent curriculum, to improve students' environmental awareness.

The development of 21st-century technology demands more interactive and student-centered learning. However, preliminary studies at SMAN 2 Painan showed that students' critical thinking skills on heat were still low. This was due to the teacher-centered learning style, which resulted in students being less active, and the media used did not support exploration and discovery of concepts. To address these issues, this study developed an interactive, inquiry-based learning media supported by Google Sites. The development process followed the Dick and Carey model, with expert validation and practicality testing on 30 students and 3 Physics teachers. The validation results showed a Cohen's Kappa value of 0.96 (very valid), while the practicality test produced a value of 0.88 (very practical). These findings suggest that Google Sites can be an effective alternative to support inquiry-based learning and improve students' critical thinking skills. Consequently, this media can be used as an adaptive and accessible digital learning innovation. However, this study was limited to a small sample size, focused on only one topic, and did not examine the long-term impact of media use.

This study aims to develop and validate a comprehensive electronic assessment package to measure students' creative thinking abilities on the topic of Newton’s Laws. While creative thinking abilities are important to foster creativity, as one of 21st century skills, physics assessments often do not specifically measure this ability. This research addresses that gap by designing a complete and modern assessment system that uniquely integrates diagnostic, formative, and summative instruments into a single package. The study employed a Research and Development (R&D) method, adapting the Plomp model with a focus on the preliminary and prototyping stages. The feasibility of the product was tested through content validation by three experts, with the data analyzed using the Aiken's V index. The results show that all three instruments (diagnostic, formative, and summative), achieved a high validity category. In conclusion, the developed electronic assessment package is a valid and feasible instrument for comprehensively assessing creative thinking abilities in physics
