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).
GCSE (14-16 year olds) history is (supposed to) teach the various types of source (primary, secondary, etc.), and consideration of reliability, bias, etc.
For the sciences, we were required to use reasonable sources (perhaps not direct papers and journals, but certainly reasonably reputable outlets that discuss their findings.
At college level (16-19), I honestly don’t remember this being a requirement (although I did drop history). Tests and assignments were mostly based on class teaching.
At university level, it goes full force after the first year. Everything you assert, you have to back up, using the university’s preferred referencing system.
