My pre-uni ed was mostly in the 90s, here in Brazil. I was taught proper research skills since the 4th grade of the primary school (10yo), but in a heavily simplified way: you were expected to check the library and make a simple paper-like assignment about some random topic. The assignment had to follow intro, then "main", then conclusions, then bibliography. Then as the school years progressed those requirements became more and more refined, to the point that a good 3rd grade student in the secondary school (17yo) was supposed to be able to write a simple technical paper. ("supposed to" is key here - most couldn't anyway. Including me.)

Media literacy? Nope. Can't have kids thinking by themselves, right, what if they become questioning adults *rolls eyes*.
