Re: 'Fake news'
A third of my English course tenth grade high school did exactly that, teach critical thinking. Everything from spotting indicator words, types of and recognition of the common fallacies, the usual. I've no idea if they even bother these days. Hell, I bet they don't teach kids this as it would prevent manipulation of them in the future towards whatever causes are du jour.
I happened to select philosophy as one of my electives that year and had great fun on the English side as my philosophy teacher through in a unit on logic including predicate calculus. Very nice tools to line up targets to demolish academic, or media for that matter, arguments. All my notes after that were in this format. Good fun, especially for an academic at heart.
