This article reviews the results of a quantitative study that provides evidence of gender biases in relation to women in the field of Spanish mathematics education. For this purpose, doctoral dissertations produced in Spain and defended in Spanish universities between 1970 and 2014 were subjected to exhaustive analysis. Focusing on gender, the authorship, supervision, and evaluation of doctoral dissertations were used as explanatory variables. A prospective analysis of the variables was also carried out. The results reveal different situations depending on the abovementioned dimensions. Specifically, a marked bias against women was detected in terms of the supervision and evaluation of doctoral dissertations, but not in terms of their authorship. This seems to suggest the existence of a glass ceiling that prevents women from gaining access to certain scientific fields and/or engaging in particular roles in the higher education setting, such as the supervision or evaluation of doctoral dissertations.
ResumenLos resultados de este estudio sugieren prejuicios en relación a las mujeres en la disciplina de educación matemática en España. El análisis de tesis doctorales españolas, en el campo de la educación matemática, indica un marcado prejuicio contra mujeres en términos de supervisión y evaluación, pero no de autoría. Esto sugiere la existencia de un techo de cristalque dificulta el acceso de mujeres, en
