This article presents an overview of the recent literature on gendered patterns of academic choice in mathematics, science, and technology. It distinguishes in this literature microlevel, macro-level, and institutional explanations. Micro-level explanations focus primarily on psychological constructs, that is, variables at the level of the individual students. Macro-level explanations focus primarily on socioeconomic conditions and cultural understandings of gender roles. Institutional explanations focus on design characteristics of (national) education systems. After a presentation of these perspectives and of recent research progress that has been made, the authors critically discuss the lacunae that still exist in explaining cross-national variety, and provide suggestions for designing future research in this field.Keywords: gender; education; academic choice; mathematics; science and technology Introduction Female participation in higher tertiary education has increased rapidly over the past decades.1 Currently, about 56% of all students in the European Union are women, and this figure is still rising (Eurostat, 2010). Yet, this increase in female student participation does not apply to all academic fields. In mathematics, science, and technology (MST), where women have always been underrepresented, their participation rate has actually decreased over the last years, from 41% at the end of the 1990s, to 38% in 2010 (Eurostat, 2010). The relative decline of women in MST is generally regarded as undesirable as it contrasts with European ambitions of achieving gender equality and a highly skilled, innovative society (European
