The purpose of this study was to investigate the misconception of light refraction at the plane intersection of 32 students, 4th-6th grade elementary-school J located at the G-region. At the plane of incidence, the conceptions of light refraction on the students were examined into three concepts: concept of light propagation, concept of light refraction, and position of the image. The two diagnostic questions used in the study probed the students" ability to use a ray diagram to explain the relationship between object, image and observer, and then to use the ray diagram to qualitatively determine the position of the image. The results of this study were as follows: As for the transmission of light, most elementary school students understood that the light started from the eye. Also, the majority of students did not understand that the refraction of light was refracted at the interface between water and air. The students expressed the ray based on the terms they learned about the position of the image without the correct scientific reasoning process. The results of study indicate that students require very careful instruction if they are to understand how objects are seen and how images are formed when light refracts through a planar surface.
