Over the past couple of months, I have been using sociology to show how everyday experiences of sexism and racism feed into the educational and career trajectories of women and minorities in various disciplines within Science, Technology, Engineering and Mathematics (STEM). Here I include summaries of my writing from recent times, which show how social policy can dramatically impact on women’s educational outcomes. I’ve also covered how childhood socialisation impacts on girls’ transition from school to university. Experiences in higher education are also gendered, that is, culture shapes how women and men think about what happens to them at university. We see this clearly in relationships with thesis supervisors and informal socialising, as well as in more formal processes in administration. I’ve also highlighted some progress in diversity, namely the appointment of a lesbian technology expert, Megan Smith, who now holds a key role with the American government. Despite this achievement, various controversies in STEM related to social media use by scientists, research on women and high profile science events signify that despite strides forward, women and minorities are still the targets of inequality and marginalisation.
