International Comparative Pilot Study of Spatial Skill Development in Engineering Students through Autonomous Augmented Reality-Based Training.

Spatial ability is made up of several sub-components, such as the ability to perform mental rotation and object-based transformations. Together with each individual's attitudes and general skill sets, this specific ability plays an important role in technical professions such as engineering. The components of spatial ability can be enhanced using targeted training or educational programs. This study analyses the levels of spatial skills in first-year engineering students at two universities, one in Spain and one in Peru. The purpose of the study is to establish the extent of symmetry between these study groups in terms of their spatial skills. Initial comparisons indicate that the Peruvian students have a lower level of spatial skill prior to training than their Spanish cohorts. AR-based training delivering representational system content was used with engineering students at both universities to boost spatial abilities. The results obtained indicate the training was effective, as both experimental groups made significant gains in their level of spatial ability. No difference was detected in either experimental group for the variable gender. The comparison of spatial ability gains between both countries is similar, although there is significant difference in the spatial ability component spatial visualization. In this instance, gains in this component were higher amongst the student population in Peru. [ABSTRACT FROM AUTHOR]
