Abstract

The ability to comprehend and apply scientific concepts to contemporary issues is essential for the long-term growth of society. Scientific literacy enables students to understand how their bodies digest food, what it means to eat a balanced diet, and how their food choices affect the environment. The goal of this study was to create and test a STEM-based e-Book about the human digestive system that would help eighth-grade students become more scientifically literate while also teaching them about sustainability. The study utilized a Research and Development (RD) methodology based on the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Experts in media, learning design, materials, and language confirmed that the product was valid. They showed that the e-Book would perform well in the classroom. Thirty-eight-grade students at a private junior high school in Medan were involved in the implementation. A pretest measured how well something worked. We used pretest and post-test assessments to evaluate the effectiveness. The results showed a significant improvement in students’ scientific literacy. Most of the students scored above the minimum mastery level, with an average N-Gain in the high range (0.75). Feedback from students and teachers indicated that the e-Book was helpful for both classroom and independent learning. The results suggest that integrating STEM principles and sustainability topics into digital learning resources can significantly improve scientific literacy and promote health awareness grounded in sustainability among junior high school students.

Abstract

Colloid learning is often difficult for students to relate to real-world phenomena, leading to a lack of conceptual understanding and critical thinking skills. One relevant local context for concretizing the concept of colloids is tofu waste treatment, which involves colloidal systems and environmental issues in the community. Integrating this ethnoscience context through Challenge-Based Learning has the potential to provide more contextual, meaningful, and authentic learning oriented toward problem-solving. This study aims to develop and demonstrate the impact of a Challenge-Based Ethnoscience e-book about colloids in the context of tofu waste treatment on improving students' conceptual understanding and critical thinking skills. This research method used Design and Development Research, consisting of three phases: design (needs analysis and product design), development (based on the 4STMD model), and evaluation (Students' critical thinking and conceptual understanding). Implementation was conducted with 30 eleventh-grade students. Critical thinking skills were measured using the Ennis framework, while conceptual understanding was assessed through context-based essay questions. Data were analyzed using the Wilcoxon test, Spearman correlation, and rank-biserial effect size. Results showed significant improvements in conceptual understanding and critical thinking skills, indicating consistent positive score changes across all participants. A very strong correlation was found between conceptual understanding and critical thinking skills, indicating a high degree of shared variance between the two. It can be concluded that the CBL e-book on ethnoscience related to colloid materials, developed according to the 4STMD, is a feasible and effective learning material for chemistry. This learning material aligns with the learning curriculum, is scientific, and organizes materials systematically through local wisdom, specifically in the context of tofu wastewater treatment, to enhance students' understanding of concepts and critical thinking skills.
