Abstract

This study was conducted to assess the contribution of the REACT model in enhancing students’ critical thinking skills in learning about substances and their changes at a public junior high school in Serang City. A quantitative approach was employed, using a pretest–posttest control group design, where Class VII C served as the experimental group applying the REACT model, while Class VII A functioned as the control group using the PBL model. Data were collected through multiple instruments, including interviews, questionnaires, test documentation, and observations, and were subsequently analyzed using homogeneity and normality tests, followed by an independent sample t-test. The results indicated an increase in the experimental group’s posttest mean score to 78, outperforming the control group’s mean score of 66, with a significance value of 0.003, below the 0.05 threshold. These findings confirm that the implementation of the REACT model effectively enhances students’ critical thinking skills through the stages of Relating, Experiencing, Applying, Cooperating, and Transferring. Therefore, the REACT model can be considered a viable alternative science teaching strategy that supports the development of students’ critical thinking abilities.

Abstract

This research is based on the low critical thinking skills of students and the limited use of interactive teaching materials in the learning process at school. Based on these conditions, interactive teaching materials based on Ethno-STEM were developed which function as learning support tools to support the critical thinking skills of junior high school students. This study aims to examine the level of validity and student responses to Ethno-STEM-based E-LKPD in the study of milkfish satay processing. The research method used is Research and Development (R&D) by adopting the ADDIE model which includes the stages of analysis, design, development, implementation, and evaluation. The research instrument consisted of a validation sheet filled out by experts and a student response questionnaire. The data obtained were analyzed using qualitative and quantitative descriptive techniques. The results showed that the developed E-LKPD obtained an average validity value of 91.5% with a "Very Valid" category based on the assessment of teaching material experts, material experts, and practitioners or junior high school science teachers. After going through the revision stage, the product was tested on a limited basis and received a positive response from students with a percentage of 86.8% in the "Good" category. Thus, the E-LKPD based on Ethno-STEM is suitable for use as a supporting teaching material in learning.
