Abstract

Chemical molecules are a challenging topic for students because they are abstract and difficult to visualize. Students continue to struggle with understanding sub-microscopic concepts and lack the analytical skills necessary to solve chemical problems. Spatial and analytical abilities are essential for developing a deeper understanding of chemical molecule structures. This study aims to enhance students' spatial and analytical abilities by applying the Inquiry-Based Learning model using PyMOL as a 3D visualization medium in teaching chemical molecule structures. The method used in this study is a quasi-experiment with a pretest-posttest control group design, involving two groups of tenth-grade classes. The experimental class utilized PyMOL as a 3D visualization medium, whereas the control class employed Molymod kits. The results showed that students who learned using PyMOL experienced significant improvements in both spatial and analytical abilities. Correlation analysis showed a positive relationship between spatial and analytical abilities. Students' responses to the learning process are positive. This study demonstrates that using PyMOL as a medium for technology-based 3D visualization can make abstract concepts easier to understand and help students develop critical and systematic thinking skills.

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.
