Abstract

This study aims to diagnose difficulties and misconceptions of light refraction. This research was conducted by qualitative design. The sample consists of 84 students who were taken from the second semester of physics education at 5 universities in Indonesia. Trend data on understanding the concept of light refraction were collected using a three-tier test. Difficulties and naive reasons about light refraction were collected by interview. Students’ misconceptions are measured by the Certainty Response Index (CRI) analysis technique. The results showed that although the concepts of light refraction have been studied by students, they still have difficulty answering questions about light refraction. Students’ misconceptions occur in the aspect of the direction of wave propagation perpendicular to the wavefront with a high category and misconceptions on the value of wave physical quantities refraction in the medium category. The concept of wavefronts and the value of wave physical quantities is abstract, so it is necessary to consider learning to use PhET Simulation to visualize the concept so that it is easily understood by students.
