This study examined the impact of augmented reality (AR) on engineering education, focusing on spatial visualisation skills and cognitive load in an engineering drawing course. The research is based on cognitive load theory and spatial visualisation frameworks. It compares three AR methods--marker-based (MBAR), markerless (MLAR) and Web-based…

First-year engineering (FYE) students are routinely screened for spatial ability, with the goals of predicting retention in the major and identifying those who need supplementary spatial instruction. Psychometric tests used for such screenings are often domain-general measures that lack diagnostic information to inform remedial instruction. A new…
