The results show that teachers strongly prefer the inclusion of experimental activities (90.3%), visual illustrations (67.7%), contextual stories (64.5%), and links to video simulations (74.2%). Meanwhile, students indicated high interest in live experiments (75%), visual media, and science stories. In addition, teachers and students supported integrating environmental issues and technological innovation related to magnetism. These findings highlight the need for a contextual, visual, and narrative-based non-textbook aligned with the SDGs framework to support more meaningful and engaging science learning experiences in junior high schools

Critical thinking skills are essential competencies that students must possess to face 21st-century challenges. However, studies indicated that students' critical thinking skills in Indonesia remain unsatisfactory and, thus, need suitable approaches. One of the approaches believed to cope with this issue is the Multiple Intelligences. This article aims to examine the contribution of the Multiple Intelligences approach to developing teaching materials that foster students' critical thinking abilities. This study utilized a Systematic Literature Review (SLR) method, employing the PRISMA flow diagram for article selection. Articles were selected based on inclusion and exclusion criteria, including relevance, educational context, and international journal indexing. This article provides crucial insights for educators and researchers to optimize student-centered learning. The analysis revealed that 67% agreed that the Multiple Intelligences approach significantly improved critical thinking skills, 20% reported no influence, and 13% noted effects only on certain skill types. This research also highlights challenges, including limited teacher knowledge and skills, a lack of supporting infrastructure, and difficulties integrating with traditional methods. Future studies are recommended to develop teacher training, enhance infrastructure, integrate Multiple Intelligences-based and traditional approaches, and conduct longitudinal studies to evaluate effectiveness.

This study examined the effectiveness of e-comics based on culturally responsive teaching (CRT) in improving students' science literacy. A quasi-experimental design was employed with seventh-grade students at SMP Negeri 3 Lasem in the 2024/2025 academic year as the population. The sample was selected using cluster random sampling, with Class VII C assigned as the control group and Class VII D as the experimental group. Data were collected using a scientific literacy test and analyzed through quantitative and descriptive methods. The findings revealed that e-comics based on CRT significantly improved students' scientific literacy. The experimental group achieved an average N-gain score of 0.64 (moderate category), which was higher than the control group's average of 0.40. A Mann–Whitney test confirmed a significant difference between the two groups (p < 0.05). These results indicate that e-comics grounded in CRT are effective in enhancing junior high school students' scientific literacy.

The increasing consequences of global climate change underscore the necessity for the integration of low-carbon education and renewable energy frameworks within the educational paradigm for learners. This study develops a training curriculum for Youth Scientific Paper/Karya Ilmiah Remaja (KIR) that incorporates these principles to enhance students' scientific proficiency. Utilizing a Systematic Literature Review (SLR) approach, thirty indexed scholarly articles from the last decade were rigorously analyzed. The results reveal that the inclusion of low-carbon education and renewable energy within KIR training programs significantly improves students' abilities in critical thinking, problem-solving, and data analysis while concurrently fostering environmental awareness. Effective implementation strategies include project-based learning, hands-on renewable energy experiments (such as solar panels and wind turbines), and collaborations with environmental organizations. However, challenges such as limited resources, insufficient mentor training, and inadequate policy support hinder successful implementation. Despite these obstacles, the integration of low-carbon education and renewable energy within KIR initiatives holds substantial promise for cultivating environmentally responsible scientific skills among students. This initiative aligns with the Sustainable Development Goals (SDGs), particularly SDG 4 (Quality Education), SDG 7 (Affordable and Clean Energy), and SDG 13 (Climate Action), thus contributing to a more sustainable future.
