# Perception of the Use of Virtual Reality Didactic Tools among Faculty in Mexico
## 3 Results
Males have a higher self-concept of their digital skills than females in Health Sciences, Social Sciences, and, above all, in Engineering--an \begin{table}

The higher level of digital skills is accompanied by a higher rating of the technical and didactic characteristics by males in not only Engineering and Social Sciences but also in Humanities--although in this area, males have fewer digital skills; and by a lower rating of the disadvantages of VR in the case of males in Engineering, Sciences, and Social Sciences (Figure 6b-d). In Sciences, females outperform males in the ratings of all the variables analyzed, while in Humanities, it is females who outperform males, except in the digital skills variable. In

Table 5: Descriptive statistics of the responses to the different families of questions and statistics of the Kruskal–Wallis test for comparison of mean values. Engineering and Social Sciences, males outperform females in their ratings of digital skills and the technical and didactic aspects of VR, but females identify more disadvantages of VR than males.
