2025-09-09T11:05:17+00:00

This research aimed to develop a science teaching module based on ethnoscience by integrating the local tradition of Tedhak Siten as an innovative approach to learning. It seeks to improve the understanding of scientific concepts through a contextual approach that is relevant to the local culture, to spark students' interest in science, and to strengthen the local cultural identity within the educational process. This study used the Research and Development (R&D) method with the ADDIE model approach (Analyze, Design, Development, Implementation, Evaluation). The research stage in this study only reached the Development stage. This module was designed to integrate concepts of growth and development in science with the cultural values of the Tedhak Siten tradition, making learning more contextual and relevant to students' lives. Based on data analysis, the validation results showed that the module received an average score of 94% from content experts and 96.4% from media experts, categorized as “highly valid” and not requiring revision. Therefore, this teaching module is declared fit for use in teaching science to grade IX students in SMP/MTs.

The Effect of the ReCODE Learning Model on Students' Critical Thinking Skills and Scientific Literacy

2025-08-01T03:17:03+00:00

This study aimed to develop students' critical thinking skills and scientific literacy. This type of research is a quasi-experimental research, using a Non-Randomized Control Group research Design. The sample of this study was divided into 2 groups, namely the experimental group and the control group. The data collection technique was carried out through 5 essay questions for each variable, namely critical thinking skills and scientific literacy skills. The results of the t-test showed that sig. (2-tailed) of 0.000 was smaller than 0.05, which means there was an influence on the critical thinking skills and scientific literacy of MTsN 2 Kaur students. Teachers are advised to start implementing the ReCODE model gradually, especially in science learning that emphasizes conceptual understanding and high-level thinking. Schools and policy makers are expected to provide support in the form of adequate training and learning facilities.

2025-07-17T07:59:28+00:00

Current environmental problems are often referred to as the triple planetary crisis, where this phenomenon refers to three environmental problems, namely climate change, pollution and biodiversity loss. This phenomenon occurs because of the lack of public concern for the environment. In the midst of the environmental issue phenomenon, a person must be able to protect the environment, the most effective way to produce a generation that cares about the environment can start from the world of education. Based on observations and interviews that have been carried out, the current ecoliteracy skills of students are still not optimal, so this study aims to describe the results of validation from experts and readability tests by students on the development of ecoliteracy-based pocket books for junior high school students in grade VII on the material of interactions between living things and the environment. This study uses the Research and Development method with the ADDIE (Analyze, Design, Development, Implementation and Evaluation) development model, implemented at a Public Junior High School in Serang City with a sample of 30 grade VII students. The analysis was carried out qualitatively and quantitatively with the results of the study showing that ecoliteracy-based pocket books have a "very valid" level of validity. Validation by experts obtained a percentage of 84% and readability test with a percentage of 88%. Based on the results, the developed teaching materials are considered very valid, so they are worthy of being used for the learning process and further testing on a wider scale.
