    The usage of 3D modeling in teaching geometry in high school
    (SDU University, 2026) Serikbay Zh.
    This study examined the effect of 3D modeling tools on Grade 11 students’ spatial abilities and academic achievement in geometry. The research used a quasiexperimental design with two nonequivalent groups: 25 students in the experimental group and 25 students in the control group. The experimental group studied solid geometry using Tinkercad and SketchUp Free, while the control group studied the same topics through traditional instruction. Data were collected through the Purdue Spatial Visualization Test (PSVT), geometry grades before and after the intervention, and a questionnaire on students’ attitudes toward 3D modeling. The results showed that the experimental group had a statistically significant improvement in spatial ability, while the control group did not show significant change. However, geometry grades increased only slightly and equally in both groups, so the effect on general academic achievement was not clearly demonstrated. Students generally showed a positive attitude toward 3D modeling. The study concludes that Tinkercad and SketchUp Free can support the development of spatial visualization, mental rotation, and spatial orientation in high school geometry.
