Using mental rotation tasks and stress measurements via Garmin Vivosmart 5, the study found no significant stress increase or VR sickness when using VR compared to 2D tasks. VR improved accuracy for most participants and was preferred over 2D. The study highlights the potential of VR in enhancing spatial learning but acknowledges limitations, such as the small sample size and controlled environment.deGesellschaft für Didaktik der MathematikBeiträge zum Mathematikunterricht; 58Übergang Primarstufe Sekundarstufe ISekundarstufe I allgemeinbildendKommunizierenRaumgeometrieDarstellenUnterrichtsmethodenLernumgebungenDarstellungen und VorstellungenMINT (resp.
