Techniques used to Improve Spatial Visualization Skills of Students in Engineering Graphics Course: A Survey <s> K. Training website: <s> This work follows up the validation and usability study done over an augmented reality based application for the development of the spatial skills of engineering students. In this paper can be found all work done prior to its commercial launch for widespread use. In addition, a study will be done to find out the influence of the display device (computer screen or head-mounted display) in terms of spatial ability acquisition and improvement, as well as the time required in terms of using them. <s> BIB001 </s> Techniques used to Improve Spatial Visualization Skills of Students in Engineering Graphics Course: A Survey <s> K. Training website: <s> article i nfo Article history: This one-year longitudinal study investigated the benefits of spatial training among highly gifted science, technology, engineering and mathematics (STEM) undergraduates (28 female, 49 male). Compared to a ran- domized control condition, 12 h of spatial training (1) improved the skills to mentally rotate and visualize cross-sections of 3-D objects shortly after training, (2) narrowed gender differences in spatial skills shortly after training, and (3) improved examination scores in introductory physics (d=.38) but not for other STEM courses. After eight months, however, there were no training differences for spatial skills, STEM course grades, physics self-efficacy, or declared majors. Large gender differences, favoring males, persisted for some spatial skills, physics grades, and physics self-efficacy eight months after training. These results suggest that sustained exposure to spatially enriching activities over several semesters or years may be necessary to address gender gaps in spatial skills among highly gifted STEM undergraduates. <s> BIB002
