Development of PBL Stem-Based Science Learning E-Module to Increase Critical Thinking and Creativity in Global Warming Materials

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.
