Abstract

Molecular geometry is one of the biggest challenges in science education. Since molecular structures exist at a microscopic level, students often struggle to visualize them in three dimensions (3D), making it difficult to understand concepts such as bond angles, molecular shapes, and electron pair interactions. This study explores the role of spatial ability in high school students’ understanding of molecular geometry. Using a quantitative descriptive method, the study examined the spatial ability and molecular science comprehension of 58 high school students. Data were collected using standardized tests, including the Mental Rotation Test (MRT), shape assembly, and 3D visualization for spatial ability, along with a molecular science comprehension test focusing on VSEPR theory. The results obtain that students' spatial ability is significantly low, with average scores falling far below expected standard. The results suggest the need for more effective teaching strategies that incorporate 3D visualization tools to enhance students’ ability. Future research should focus on interactive learning approaches, such as virtual simulations to help students better visualize molecular structures and improve their understanding of science concepts.

Abstract

The development of 21st-century education in Indonesia necessitates equipping students with essential competencies such as problem-solving skills (PSS), particularly in chemistry learning, where real-world relevance is crucial. This study explores the integration of the Science, Environment, Technology, and Society (SETS) approach into Problem-Based Learning (PBL) as a strategy to enhance students' PSS in chemistry. Employing a Systematic Literature Review (SLR), this research analyzed 127 articles from five databases (SCOPUS, Google Scholar, Semantic Scholar, Taylor & Francis, and ERIC) published between 2020 and 2024. After applying inclusion and exclusion criteria based on relevance to PBL, SETS, PSS, and secondary chemistry education, 14 high-quality articles were selected for in-depth analysis. The review revealed that integrating SETS into PBL positively impacts students' ability to analyze, reason, and apply chemical concepts in solving contextual problems. However, challenges such as teacher readiness, curriculum constraints, and limited assessment tools were also identified. This study contributes to the literature by mapping trends and identifying best practices for implementing PBL-SETS in chemistry education. Despite its comprehensive scope, the review is limited by potential publication bias and the exclusion of non-English studies. These findings suggest the need for more empirical studies and professional development programs to support teachers in adopting PBL-SETS effectively.

Abstract

The study aims to analyze the relationship between English language skills and the students' learning outcomes in chemistry learning that uses English as the medium of instruction (EMI). This qualitative descriptive study was conducted on 40 high school students. Data is collected and analyzed in the form of the test result of the language skills and learning outcomes. The results for students' language skills: 75 % of students are at level A2 (primary user), 15 % are at level B1 (intermediate), 5 % are at level B2 (upper-intermediate), and 5 % are at level C1 (advance/proficient user). The students' chemistry learning results are averagely low, i.e., 70 % of students gained a score under 75 as the minimum criteria of standard learning,  only 30 % of students reached the score above the KKM (Criteria of Minimum Competency). The conclusion of this research is that there is a relationship between language skills and chemistry learning outcomes. Learning chemistry in English has not given good results for students' learning outcomes. Therefore, the demands of learning in English need to be supported by good language skills to understand the learning content.
