I'm sure this will vary for many people depending on their schools, where/when they were taught, and the like, so I'm interested to see what others' experiences have been with this.
I'm also curious about what resources some have used to learn better research skills & media literacy (and found useful) if their school didn't adequately teach either (or they may have whiffed on it at the time).
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*.
