Abstract

The purpose of this study was to enhance critical thinking skills through the implementation of coastal culture-based differentiated science learning. The research was conducted from August to November 2024 using a quasi-experimental nonequivalent control group design at  State Junior High School 2 Bengkulu, Indonesia. The sample consisted of three eighth-grade classes: experimental group 1 (8A), experimental group 2 (8B), and the control group (8C), selected through purposive sampling. Students’ critical thinking skills were assessed using a validated and reliable test instrument (r = .89). Data were analyzed with one-way ANOVA, which revealed significant differences among groups (p < .001). The average N-gain score of critical thinking skills in experimental group 1 (.40, medium category) was higher than that of experimental group 2 (.20, low category) and the control group (.009, low category). Based on the hypothesis testing, it can be concluded that coastal culture-based differentiated science learning has a significant effect on students’ critical thinking skills (p < .001). These findings confirm that culturally contextualized differentiated learning significantly enhances critical thinking. Theoretically, this model contributes to science pedagogy by integrating cultural relevance to support effective, innovative instruction

Abstract

This study investigated the effectiveness of integrating the 9E Learning Cycle Model with STEM approaches to enhance students' Science Process Skills (SPS) in static fluid concepts. The research employed a mixed-methods embedded experimental design with 32 senior high school students. Quantitative data were collected through pre- and post-tests, while qualitative data were gathered via observations and interviews. Results showed significant improvements across all SPS components, with N-gain values ranging from 0.63 to 0.64, indicating medium gains. Students demonstrated enhanced abilities in observing, classifying, measuring, inferring, predicting, and communicating scientific concepts. The integrated approach facilitated practical application of knowledge, as evidenced by students' work on flood-resistant garage prototypes and wave-powered electricity generators. Qualitative findings revealed increased student engagement and improved problem-solving skills. The study concludes that the integration of the 9E Learning Cycle Model with STEM approaches offers an effective framework for enhancing students' science process skills and their ability to apply these skills to real-world problems. These recommendations aim to provide a more comprehensive understanding of the approach's potential in science education across various domains and student populations

Abstract

Biogas is a renewable, environmentally friendly energy source with significant potential for science education, offering an alternative to the global fossil fuel crisis. This study aims to provide a brief overview of research trends, publication contributions, methodologies used, thematic coverage, and teaching integration in the biogas-based science education literature. This study is a Systematic Literature Review (SLR) with bibliometric analysis, supported by Publish or Perish and VOSviewer, including 720 selected articles from the period 2015 to 2024. The results show that, since 2020, publications related to biogas have increased significantly, with three main research focuses: the use of organic waste for renewable energy development; the application of biogas as an alternative global energy source through technological innovation; and its integration into HOTS learning and education. The majority of the publications come from reputable international journals such as Energies and Sustainability. Case studies and reviews remain the dominant research protocols, while empirical designs such as experiments and surveys are still relatively rare, leaving room for more applied follow-up studies. This review also finds that the application of biogas in science education can support the development of Higher Order Thinking Skills (HOTS). However, this application remains limited in the existing literature. Therefore, the findings highlight the need for further empirical research to more deeply explore the potential of biogas for science education and HOTS development. This study provides new insights that the biogas literature has not fully integrated practical applications for HOTS development, thus requiring further creative and applied research to address this gap. Keywords: alternative energy, biogas, environmentally friendly, HOTS, science education.
