Abstract

This research project aimed to obtain data on learning outcomes using the Project-Based Learning (PjBL) method related to STEM activities in honing students' critical thinking skills in bioplastic manufacturing projects. This research used quantitative method with one group pretest-posttest design. The research targets were VII A students of SMP Negeri 1 Nalumsari as many as 22 students. The research instruments were pretest and posttest tests with analysis of homogeneity test, normality test, and N-Gain test. The test results showed that all data were normally distributed and homogeneous, so it was feasible to analyze further. The overall N-Gain average was 0.6029 (medium category), indicating an increase in critical thinking by 60.29% after learning. The indicators with the highest improvement were problem identification and analysis, while problem solving and drawing conclusions experienced low improvement. Although there are differences in each indicator, all stages of PjBL from problem determination to experience evaluation are proven to contribute to the development of students' critical thinking. This research shows that STEM-PjBL through bioplastic projects can be an alternative to contextualized science learning and 21st century skill oriented.

Abstract

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.
