Factors associated with the gender gap in the STEM sector: Comparison of theoretical and empirical concept maps and qualitative SWOT analysis.

Science, Technology, Engineering, and Mathematics (STEM) degrees represent a future employment scenario with low unemployment rates due to the high demand for qualified personnel. However, the STEM sector also represents an educational field marked by horizontal segregation and the gender gap. Different factors play a role in deciding which higher education studies to pursue. From a theoretical and empirical approach, this study aims to identify which factors are associated with the gender gap in the STEM higher education sector. Furthermore, as a research question, it is proposed: are the factors identified at a theoretical and empirical level associated with the gender gap in the STEM higher education sector the same? The empirically validated questionnaire "Questionnaire with university students on STEM studies in Higher Education" (QSTEMHE) was applied to the student community of public and private universities in Spain in 2021, using simple random probability sampling to answer the research question and objective. A final sample of 2101 participants of different genders belonging to different branches of knowledge was obtained. The data analysis was carried out using qualitative methodology and the phenomenological method, following different stages. Firstly, a theoretical conceptual map of the main factors identified in the literature and their authors was composed. Secondly, an empirical conceptual map has been designed with the factors identified in the narratives of the study participants. Finally, these maps were complemented with a SWOT analysis based on the participants' discourses. As a result, it has been observed that there are extrinsic and intrinsic factors and that social constructs and gender stereotypes strongly influence the perception of men, women, and professions and the masculinisation and feminisation of these. Outreach interventions should be proposed from the institutional educational spheres to alleviate existing biases about studies and professions.
