The research aims to enhance 11th-grade students' understanding of parallel and perpendicular projections using augmented reality.
Utilized action research methods.
Implemented GeoGebra 3D Calculator software for AR-enhanced learning experiences.
Compared post-test scores of AR-assisted group with a historical control group from the previous academic year.
Post-test scores for the AR-assisted group averaged 8.2, significantly higher than 6.5 for the control group.
Demonstrated a large effect size of Cohen’s d = 1.24.
Indicated a deeper understanding of spatial geometry among the students using AR.

Nam et al. (2026) studied this question.
