This study examines the application of the Project-Based Learning (PjBL) model in Natural and Social Sciences education to enhance environmental awareness among fifth-grade students at SDIT Wihdatul Ummah in Makassar City. The background of this research stems from the low environmental awareness observed among students, evidenced by behaviors such as littering, lack of concern for energy conservation, and minimal participation in school cleanliness activities. The study aimed to improve students' environmental consciousness by implementing the PjBL model, where students were tasked with creating environmental awareness posters. The research used a Classroom Action Research (CAR) method, which was carried out in two cycles, each consisting of three meetings. The stages of PjBL involved determining essential questions, project planning, scheduling, project implementation, result testing, and evaluation of experiences. Data collection was done through observations, attitude questionnaires, and documentation of student activities. The findings showed that the PjBL model successfully increased students' active participation, creativity in expressing environmental awareness through posters, and their practical actions toward environmental protection. The environmental awareness indicators, such as maintaining cleanliness, managing waste, conserving energy, understanding waste disposal systems, and using cleaning tools, significantly improved from Cycle I to Cycle II. The results indicate that the PjBL model is effective in enhancing environmental awareness while making the learning process more engaging and contextual for elementary school students.

Natural Science (IPA) learning is an important foundation in developing students' scientific literacy, critical thinking skills, and scientific attitudes. However, the learning process still faces many challenges related to low learning interest, the dominance of conventional methods, and limited use of technology. This article aims to analyze the effectiveness of innovative approaches in science learning through a systematic review of 25 national and international journal articles published in 2020–2025. The systematic review method was carried out through the stages of identification, selection, data extraction, and thematic analysis. The results of the analysis show that the Problem-Based Learning (PBL), Inquiry-Based Learning (IBL), STEM Learning, and digital technology integration (PhET Simulation, mobile learning, gamification, blended learning) approaches have been proven to have a positive impact on learning outcomes, critical thinking skills, creativity, and student motivation. The thematic analysis resulted in four main themes: (1) strengthening critical thinking skills through PBL, (2) developing creativity and scientific literacy through IBL, (3) STEM integration to improve collaboration and scientific attitudes, and (4) utilizing digital technology for motivation and understanding abstract concepts. This study concludes that a combination of various innovative approaches is needed to make science learning more relevant to the demands of the 21st century.

The study aims to develop and evaluate STEM PBL-based science learning media to enhance students' critical thinking and creativity. The objectives include describing, producing, and assessing the feasibility, validity, practicality, and effectiveness of these media for grade VII students. This Research and Development (R&D) study follows the 4D model: define, design, develop, and disseminate. The developed media take the form of a digital Flipbook accessible via smartphones and PCs. A limited trial involved 22 students and one educator, while a field test included 51 students from SMPN 1 Binongko, Wakatobi Regency, divided into experimental and control groups. Data were collected through tests, interviews, questionnaires, and validation sheets. Feasibility, validity, and practicality were analyzed descriptively, while effectiveness was evaluated using the N-Gain, MANOVA, and Cohen's effect size tests. The results indicate that the STEM PBL-based Flipbook presents real-life problems, their causes, and solutions, encouraging critical thinking and creativity. It meets validity and feasibility criteria as assessed by expert lecturers. Educators and students also rated it as highly practical for learning. Finally, the Flipbook was found to be effective in improving students' critical thinking and creativity, with a significance value of 0.000 < 0.05.

This study aims to analyze the effect of integrating the STEM (Science, Technology, Engineering, Mathematics) approach in science education on students' creativity and problem-solving abilities at SMPN 1 Cigombong. The STEM approach was implemented to provide an integrated learning experience, allowing students to connect science concepts with technology, engineering, and mathematics. The research method used is classroom action research (CAR), conducted in two cycles, with observation, tests, and interviews as instruments for data collection. The results showed that the implementation of the STEM approach improved students' creativity and problem-solving skills, as well as facilitated students in applying science concepts in daily life. Furthermore, students also demonstrated an increase in collaboration and communication skills. These findings contribute to the development of more relevant learning methods that meet the demands of 21st-century education in secondary schools.

This study examines the effectiveness of STEM (Science, Technology, Engineering, and Mathematics) education in enhancing problem-solving skills among high school students. With the increasing demand for critical thinking and problem-solving abilities in the workforce, STEM education has become a crucial approach to preparing students for future challenges. The study aims to evaluate how project-based STEM curricula impact students' creativity, analytical skills, and overall problem-solving capabilities. Using a quasi-experimental design with a control group, the research was conducted with high school students who participated in STEM-based lessons involving the 5E instructional model. Data collection involved pre- and post-tests, classroom observations, and semi-structured interviews to measure changes in student skills. The findings indicate that students exposed to STEM education demonstrated significant improvements in problem-solving, creativity, and analytical thinking compared to their peers in traditional lecture-based classes. The study highlights the advantages of project-based learning in promoting active student engagement and fostering skills necessary for addressing real-world problems. These results suggest that STEM education can be more effective than traditional methods in cultivating essential 21st-century skills. The study recommends the broader implementation of STEM strategies in secondary education and further exploration of the long-term impact of STEM learning on various skills required in the professional world.
