What about tech clubs? Girls Who Code clubs are run in schools and libraries across the world on a more-or-less volunteer basis, to encourage girls & young women to explore information technology and consider studying tech. Informal clubs might be more suitable for building tech literacy than the classroom.
Speaking personally, I think the biggest boost to my tech literacy came just from ongoing exposure to laptops and desktops. There is a world of difference between the freedom of a laptop or desktop user and a smartphone user.
