Emerging technologies are providing opportunities for designing new learning environments, especially environments in which students can learn by putting their skills into practice. Knowledge about the development of these experiences needs to be accumulated and processed so that they can be integrated effectively into training programmes. In this study we describe how transferable skills such as self-management and teamwork have been developed by 70 Spanish students of Education and Marketing. The learning experience comprised a serious game designed in a 3D simulation environment. For the analysis, two analytical rubrics were taken as references. Descriptive statistics and non-parametric tests such as Mann-Whitney "U" and Spearman "rho" were conducted for comparison and correlation analysis. Our results showed that the students performed well and had a positive perception of the suitability of using the simulation environment for the development of transferable skills. We also found that women performed better than men in activities involving teamwork, especially communication tasks.
