Abstract

This service is carried out for the introduction of writing hijaiyah letters using card media. Community service carried out directly by researchers within one day at one of the Islamic education institutions, namely TK / TPA Nurul Ihsan Kalampangan. The use of card media helps in introducing and learning to write hijaiyah letters. Conducive environment and hands-on approach in learning contribute positively to children's creativity in understanding and writing hijaiyah letters. The use of hijaiyah letter card media can determine the ability to write in children, besides that it can also attract interest and motivation so that children are enthusiastic about learning. That way children are easy to do learning to write hijaiyah letters.

Abstract

In the context of global environmental challenges, this study aims to identify significant gaps related to the absence of a comprehensive assessment tool to evaluate STEM literacy within the framework of a geoscience project. The subjects of the study included a population of 254 respondents, with sampling using a simple random sampling technique that resulted in a minimum sample of 155 respondents. The data collection method was carried out through a systematic problem analysis technique, including needs analysis and field research. Data collection was designed to obtain accurate and representative information by considering an error rate (e) of 0.05. The data analysis method used Confirmatory Factor Analysis (CFA) with Lisrel software, which tested the structural legitimacy of the research data. The feasibility test criteria included the Goodness of Fit Index (GFI), Adjusted Goodness of Fit Index, and Root Mean Square Error of Approximation. The results showed very strong psychometric characteristics of the instrument, with content validity reaching an Aiken coefficient of 0.99, construct validity with a good model fit index, and construct reliability (CR) of 0.83. The instrument consists of ten items covering four main STEM literacy indicators: Science, Technology, Engineering, and Mathematics. The conclusion of the study confirms that this instrument is not just an assessment tool but a transformative mechanism to develop students' interdisciplinary skills in facing the challenges of the 21st century. The contribution of this study is significant in providing an epistemological foundation for STEM education, emphasizing the importance of interdisciplinary literacy in preparing a generation that is able to compete in an increasingly complex global landscape.

Abstract

Developing students’ problem-solving skills is a central aim of modern science education, yet many learners continue to struggle when applying physics concepts to authentic situations. In Indonesia, this challenge remains urgent, as national and international assessments consistently highlight gaps in higher-order thinking and reasoning. Responding to this need, the present study sought to investigate the effectiveness of a problem-based learning (PBL)–based electronic module (e-module) designed around Polya’s four problem-solving stages in improving high school students’ abilities in the static fluid topic. Using a pre-experimental one-group pretest–posttest design, the study involved 28 students who completed validated pretest and posttest instruments aligned with Polya’s framework. Data were analyzed descriptively and inferentially through the Wilcoxon Signed-Rank Test, normalized gain (N-gain), and Cohen’s d effect size. The results showed a clear increase in mean scores from 47.91 on the pretest to 73.11 on the posttest, with all four indicators: understanding the problem, planning solutions, implementing strategies, and evaluating outcomes. The Wilcoxon test confirmed statistically significant improvements for all participants, with an effect size of 1.971 indicating a very large practical impact. These findings demonstrate that integrating PBL with structured digital scaffolding can meaningfully enhance students’ problem-solving skills. The novelty of this research lies in adapting Polya’s classic model into an interactive e-module format and embedding it within PBL to promote inquiry and reflection. Overall, the study contributes to physics education by providing evidence that digital PBL resources can narrow performance gaps and foster deeper, more equitable learning outcomes in line with 21st-century educational demands.
