Due to the difficulty in understanding and learning Descriptive Geometry, combined with the lack of development of spatial abilities of most freshmen in engineering courses, an innovative tool based on Virtual Reality techniques was developed to support teaching the theme. The central hypothesis tested was whether the use of modern stereoscopic systems in the teaching-learning process facilitates visualization and the understanding of complex spatial situations and therefore supports the development of spatial cognition of students, especially of those with lesser ability. In general, the three student groups analysed showed improvements in the development of their spatial skills (p 0.001). However, a statistically significant difference could not be detected by the analysis of average gains offered by the different treatments used in the experimental research.
