Abstract

This research aims to develop and evaluate a high-quality Complex Problem Solving (CPS) test instrument based on global warming issues to assess students' Computational Thinking (CT) skills. Global warming was chosen because of its contextual relevance in 21st-century education and its potential to promote higher-order thinking. The instrument consists of six essay questions that require students to demonstrate complex problem-solving skills, including decomposition, pattern recognition, abstraction, and algorithmic thinking. The method used in this study is Research and Development (RD), which contains five stages: (1) analysis of needs, (2) development of the instrument, (3) validation by an expert, (4) trial instruments, and (5) data analysis using the Rasch Model. This instrument was evaluated using the Rasch model to examine the validity, reliability, and difficulty level of its items, which were analyzed using the Minister 3.80.1 software. The results showed that the instrument achieved the "very valid" categories for content and construct validity. The raw variance explained by the measure was 76.20%, classified as "specific," indicating strong empirical validity. The Cronbach's alpha (KR-20) value was 0.91, indicating the instrument's high reliability. The item reliability value was 0.94, and the person reliability was 0.89. This means that students' consistency in answering questions was good, and the instrument had high reliability. The distribution of item difficulty levels was balanced, allowing students to be distinguished by their abilities at various levels. It can be concluded that this instrument is reliable and valid. Thus, this instrument can measure students' computational thinking skills on global warming.

Abstract

Technology Engineering Literacy (TEL) represents an essential competency in the 21st century, encompassing the ability to understand, evaluate, and apply technological and engineering concepts in everyday life and professional settings. This study was conducted to compare the TEL profiles of high school students engaged in Science, Technology, Engineering, and Mathematics (STEM) and non-STEM fields, with a particular emphasis on the renewable energy topic. The research employed a quantitative approach and involved 125 high school students, who were selected by purposive sampling techniques. Data were collected utilizing a TEL test instrument specifically designed for this research. Mann-Whitney analysis using SPSS 26 revealed a significant difference between STEM and non-STEM groups. Additionally, the TEL profiles of STEM and non-STEM students were evaluated by examining the percentages of complete and incomplete achievements. The findings show that students participating in STEM learning demonstrated a superior TEL profile compared to their non-STEM peers. Specifically, regarding the understanding of technological principles, 89% of STEM students completed the assessment, whereas only 75% of non-STEM students achieved this. In the context of developing solutions and reaching goals, 84% of STEM students met the completion criteria, in contrast to 63% of non-STEM students. For the technology and society dimension, 87% of STEM students completed the assessment, compared to only 59% of non-STEM students. In the design and systems area, 89% of STEM students completed the tasks, while 81% of non-STEM students did. Lastly, in the Information and Communication Technology (ICT) domain, 82% of STEM students reached the completion category, while merely 60% of non-STEM students did. These results emphasize the significant impact of STEM learning in enhancing students’ technology engineering literacy, thereby equipping students with essential skills relevant to the needs of the 21st century.    Keywords: technology_and_engineering_literacy, STEM, renewable_energy.

Abstract

There is no empirical evidence of the early hilal of Ramadan 1442 H that was observed through technological devices. The justification for witnessing the new moon still refers to the syar'i new moon term, not the astronomical new moon. The country of Brunei Darussalam can be used as an example when the astronomical hilal is not successfully observed, then the beginning of the hijri month is the next day or fulfills the ongoing month and there is no legal tolerance such as the use of the syar'i hilal term to replace the astronomical hilal. The integration of reckoning-rukyat is actually a methodological endeavor to perfect the criteria for the beginning of the Hijri month. Kastner's hilal visibility model is present in an effort to bridge the refinement of the criteria for the beginning of the hijri month. Through the criteria for the visibility of the hilal, Kastner offers a mathematical model that can be used as a role model for observing the hilal. Kastner's hilal visibility mathematical calculation model can be expressed in a curve that can be translated easily. Based on Kastner's hilal visibility, the early hilal of Ramadan 1442 H the hilal cannot be observed with the visual eye. Perukyat's testimony of seeing the hilal at the beginning of Ramadan 1442 H can be rejected by law because it is not based on empirical evidence in the form of a hilal image as a result of visual eye observation. According to Kasnter's hilal visibility model, the visibility of the hilal at the beginning of Ramadan 1442 H reached the maximum hilal visibility with a value of -1.68 for visual observations, the height of the hilal at the same time was 1.56 degrees (height difference between the Moon and the Sun at that time was 4, 46 degrees) with an elongation of 4.70 degrees. Observing the new moon without using tools such as a telescope, will not succeed in detecting the figure of the new moon, because the visibility of the new moon is still negative since sunset.

Abstract

Education for Sustainable Development (ESD) has become a critical focus in science learning as it addresses global challenges such as climate change, sustainability awareness, and resource management. However, research on ESD in science education lacks a cohesive understanding of its thematic trends, global contributions, and the role of educators. This study aims to analyze the research landscape of ESD in science learning, identify dominant thematic trends, determine leading countries in publications, and emphasize the importance of teacher understanding in implementing ESD. A bibliometric analysis was conducted using the Scopus database, with data retrieved on May 17, 2024, using the keywords “ESD in Science Learning.” The study analyzed 79 publications from 2014 to 2024, including journal articles, conference papers, reviews, and proceedings. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework was applied to screen and organize the data. Bibliometric mapping with VOSviewer revealed key thematic trends, including sustainability education, climate change, collaborative learning, and innovation in teaching. Results indicate that most research originates from developed countries, with social sciences and environmental science as the dominant subject areas. Additionally, findings highlight the urgent need for teacher capacity building to effectively integrate ESD principles into science curricula. In conclusion, this study provides a comprehensive overview of ESD research in science learning, identifies gaps, and highlights opportunities for future research and teacher training to promote sustainable development goals (SDGs).        Keywords: education for sustainable development, science learning, bibliometric analysis, PRISMA.DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1317-1328

Abstract

Community engagement in science is essential for building a knowledgeable and inspired society. This paper reports on the SEAROAD (Southeast Asia Regional Outreach Astronomy Development) Astronomy Workshop, a community service initiative designed to enhance science educators' understanding of astronomy and their confidence in teaching it. The two-day program in Bandung, West Java, involved 36 participants from diverse educational backgrounds. Pre-workshop assessments measured the baseline knowledge of participants on topics such as light pollution, telescope use, and celestial phenomena. At the same time, post-workshop surveys evaluated shifts in attitudes, perceived relevance, and interest in astronomy. Results revealed notable gaps in prior knowledge and demonstrated significant cognitive gains, with most participants achieving moderate to high normalized change scores. The workshop also strengthened pedagogical self-efficacy, particularly in integrating astronomy into classroom practice. This study presents one of the first systematic evaluations of an astronomy-focused teacher professional development intervention in Indonesia, implemented through a tripartite collaboration that combines local pedagogy, public science communication, and regional scientific partnerships. These findings highlight the effectiveness of short-term, hands-on, and contextually relevant professional development as a model for advancing science education and fostering sustained public interest in astronomy. Beyond its practical outcomes, this study contributes to the broader discourse on teacher professional development by offering an evidence-based framework for how collaborative, intensive, and contextually grounded astronomy training can effectively enhance both cognitive and affective domains of educators in developing countries.
