Chemistry Professor suggests new approach to improve girls' confidence in STEM subjects Professor Polly Arnold has called for girls-only science classes in schools as a short-term measure to help build confidence and eliminate harmful stereotyping such as "girls are bad at maths". In an article from the Times, Prof. Arnold explains how we can begin to address the gender bias that exists in STEM (science, technology, engineering and maths) subjects. Research shows that a segregated approach, followed by a re-integration into mixed classes, can have a positive effect on the confidence of girls in STEM subjects.
