Abstract

This development was motivated by students' low science process skills and the limited availability of teaching materials that integrate simulation technology in junior high school science learning, necessitating innovation in the form of worksheets that can facilitate discovery-based learning. This research employed the Research and Development (R&D) methodology with the ADDIE model. A pre-experimental design with one group pretest-posttest was used at the implementation stage. The research subjects were ninth-grade students. Data was collected through validation sheets for experts and practitioners, student response questionnaires for readability testing, and science process skills test instruments in multiple-choice questions. Data analysis used quantitative descriptive techniques for validation and readability data, while N-gain test and nonparametric statistical analysis with the Wilcoxon test to analyze product effectiveness. Product feasibility assessment involved media experts, content experts, two practitioners, and 10 ninth-grade students selected through purposive sampling considering different academic ability levels to assess readability. The results showed very high product validity, with average scores of 0.83 from experts and 0.97 from practitioners. The readability test achieved 96%, falling into the excellent category. Product effectiveness was proven high, with an N-gain of 0.85. The Wilcoxon signed-rank test yielded a p-value < 0.05, indicating a significant improvement in students' science process skills. Developing technology-based teaching materials can provide alternative solutions for teachers in integrating virtual practicum into science learning to improve students' science process skills.

Abstract

The study aims to develop and evaluate STEM PBL-based science learning media to enhance students' critical thinking and creativity. The objectives include describing, producing, and assessing the feasibility, validity, practicality, and effectiveness of these media for grade VII students. This Research and Development (R&D) study follows the 4D model: define, design, develop, and disseminate. The developed media take the form of a digital Flipbook accessible via smartphones and PCs. A limited trial involved 22 students and one educator, while a field test included 51 students from SMPN 1 Binongko, Wakatobi Regency, divided into experimental and control groups. Data were collected through tests, interviews, questionnaires, and validation sheets. Feasibility, validity, and practicality were analyzed descriptively, while effectiveness was evaluated using the N-Gain, MANOVA, and Cohen's effect size tests. The results indicate that the STEM PBL-based Flipbook presents real-life problems, their causes, and solutions, encouraging critical thinking and creativity. It meets validity and feasibility criteria as assessed by expert lecturers. Educators and students also rated it as highly practical for learning. Finally, the Flipbook was found to be effective in improving students' critical thinking and creativity, with a significance value of 0.000 < 0.05.
