One thing it’s very important not to forget in educational resources is younger children - even before they begin school? The pervasive nature of the decision made for children by adults very early on must have an influence. It is very striking that there are “toys” and there are “girls toys” and there are “boys toys”. That would be fine if there was an even split there, but the “toys” in particular, are subtly actually for boys - Lego springs to mind here.
Getting women into stem means bringing up little girls to be comfortable with shape, pattern and number, so that they find that maths “makes sense” when they start doing it at school. Construction toys, modelling, patterning - all these things need to not be considered boyish. And the corollary is that the traditionally girly stuff needs to be made more accessible to boys (cf that post elsewhere here about female authors…)
Not sure how ALD can address this, but if we ignore little children, than a lot of the patterns have already been set by the time we see them at high school…
