| Abstract | An experiment is a scientific procedure used to discover knowledge, test hypotheses, or demonstrate phenomena. To avoid concepts being misunderstood, refraction of light wave experiments necessitates materials that clearly demonstrate the phenomenon. As a result, researchers created a simple model of light wave refraction by rubber bands. The goal of this study is to improve students' conceptual understanding of light wave refraction before and after teaching an inquiry-based learning approach with a simple model of light wave refraction. A purposive sample of 36 students in grade 11 in the second semester of the academic year 2020 was used to establish the sample. The research tools include two inquiry-based learning approach learning plans, a simple model of light wave refraction and a light wave refraction conceptual test. The ttest statistic and Hake's method for learning gain were used to analyse the data. At a confidence level of .05, the results indicate that students' post-test scores on the refraction of light waves conceptual test were significantly higher than their pre-test scores. The Hake's method for learning gain value is 0.71, which is a high gain. It was also discovered that after studying, students provided more accurate reasoning. An inquiry-based learning approach combined with a simple model of light wave refraction has been shown to effectively improve understanding of the concept of light wave refraction. |
