Abstract

This study aims to examine the effectiveness of STREAM-integrated Project-Based Learning This study investigates the effectiveness of a Project-Based Learning (PjBL) model integrated with the STREAM–ESD (Science, Technology, Religion, Engineering, Arts, Mathematics – Education for Sustainable Development) approach in enhancing junior high school students’ critical thinking skills within the topic of biotechnology. Utilizing a quasi-experimental design, the research was conducted on Grade IX students in South Cianjur, West Java, through a kombucha tea production project grounded in real-world application and interdisciplinary inquiry. The intervention involved four stages: problem definition, data collection, building, and utilization. Results from pretest and posttest assessments revealed a significant increase in critical thinking skills in the experimental group (N-Gain = 0.7057, high category) compared to the control group (N-Gain = 0.4514, moderate category), with statistical tests confirming a meaningful difference (p < 0.05). The findings demonstrate that the integration of STREAM and ESD into PjBL fosters analytical thinking, creativity, and moral reasoning through contextual learning experiences. Moreover, the inclusion of ethical and religious perspectives encouraged students to consider the social and spiritual implications of scientific practices. This research contributes to the ongoing discourse on educational innovation by offering a sustainable, student-centered, and culturally responsive model for science education aligned with the goals of Indonesia Emas 2045 and the UN Sustainable Development Goals

Abstract

This study aimed to determine the effectiveness of STEM-integrated Project-Based Learning (PJBL-STEM) in improving junior high school students’ critical thinking skills through a water filtration project. The study employed a quantitative approach with a one-group pretest-posttest design. The research subjects consisted of 47 ninth-grade students selected using a saturated sampling technique. Data were collected through a critical thinking skills test administered before and after the implementation of PJBL-STEM learning. The test was designed to measure students’ abilities in analyzing problems, evaluating information, and drawing conclusions based on scientific evidence. Data analysis was conducted using the N-Gain test to determine the level of improvement in students’ critical thinking skills after the implementation of PJBL-STEM learning. The results showed that the average pretest score of 63 increased to 92 in the posttest, with an N-Gain score of 79%, which falls into the high category. A total of 76.6% of students were categorized in the high N-Gain category, 21.3% in the medium category, and 2.1% in the low category. Students demonstrated improvements in identifying water quality problems, designing filtration tools, analyzing experimental results, and evaluating the effectiveness of their designs. These findings indicate that PJBL-STEM learning through a water filtration project is effective in enhancing students’ critical thinking skills and providing a more contextual science learning experience.
