In this study, we examined the spatial abilities of students using eye‐movement tracking devices to identify and analyze their characteristics. For this research, 12 students aged 11–12 years participated as novices and 4 mathematics students participated as experts. A comparison of the visual‐spatial abilities of each group showed key factors of superior spatial ability, and a spatial ability instructional strategy was developed. After training, the same spatial ability test was conducted again, and eye‐tracking records were used to compare the participants' line‐of‐sight and answer rate results with those of the previous test. Specific references and recommendations are provided for spatial ability training education and assessment.
