This article discusses the design and introduction of the Light Phenomena Conceptual Assessment (LPCA) to help teachers measure their students' conceptual understanding of light phenomena. We expected to measure increases in student understanding of light phenomena after learning about the wave and particle nature of light in Rwandan secondary schools. We analyzed the results of 244 physics students using descriptive and inferential statistics. The data revealed a low understanding of light phenomena, and this low understanding is connected to instructional tools and strategies used by teachers. Students confused reflection and refraction of light. They also struggled with understanding total internal reflection and light scattering. Therefore, teachers should teach optics by allowing students to observe related phenomena in order to more effectively promote student conceptual understanding of light phenomena.
