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

There is a need to measure the environmental literacy of secondary school students to promote awareness of environmental issues and provide sustainable solutions. Environmental literacy assessment is done using the UNESCO Criteria on Education and Culture Sustainable Development (ECSD). This study aimed to develop an automatic evaluation based on Artificial Intelligence (AABAI) to measure students’ environmental literacy in science subjects and environmental issues topics. This study uses the ADDIE development model, which includes analysis, design, development, implementation, and evaluation stages. The data were examined through both quantitative and qualitative approaches using Item Response Theory (IRT). Content validity of the AABAI instrument was confirmed through Aiken’s V analysis, indicating acceptable validity levels. All test items were deemed valid based on the Rasch model, considering item fit and difficulty parameters. The AABAI instrument has been implemented in educational settings and has successfully provided a comprehensive overview of junior high school students’ environmental literacy profiles. The use of AABAI as a transformative assessment can ensure that students care more about the environment and maintain environmental sustainability.
