This research used an eye tracker to study the eye movement of elementary school students in solving a task involving the concept of light and shadow. Twenty-five fifth grade students (12 girls and 13 boys) participated. The task was created to study the students’ concepts of light and shadow by tracking their eye movements. Tobii X2-60 was used to gather the data of their eye movements, and Tobii Studio 3.2.3 was used to design the experiment and analyze the data. Three tasks were presented to the students; each task was shown for 40 seconds. Based on the collected data, we separated the students into three groups according to their task achievement and knowledge of scientific concepts. We extracted a heatmap, the fixation duration, and the number of saccades between AOI(Area of Interest) to analyze their eye movement data by types. The results show a big gap between the students depending on their knowledge of scientific concepts. The students with more knowledge of scientific concepts had a longer fixation duration on the light source, and they also showed more saccades between the light and the object than the saccades of the other students. Therefore, with more knowledge of scientific concepts, the students who understood the cause of light and shadow used their knowledge to solve the tasks.
