> I'd teach them critical thinking, because it's really the only skill they need to learn

Metacognition isn't really possible to teach. It doesn't really transfer. Everyone talks about how important it is that students "learn how to learn", but it's 99% bullshit which only refuses to die because people want it to be true.

Now, there are a few things which work. A few examples from memory (it's worth googling a bit though, as I may be wrong):

- Thinking of the brain as a "muscle", to encourage students to improve incrementally. (OK, this is new, and it's hard, but if you work on it you'll get much better with time).

- Plan, Do, Check, Act.

- Setting goals (maybe).

- Picking out a small number of key ideas for any topic (typically 3, in English speaking countries - we like 3, I think Chinese speakers like 4 but there's nothing magic, it's just a cultural preference).

But I'll reiterate - when people say "learn critical thinking", they often don't know exactly what they are talking about. Mostly, they mistake their own narrow expertise with "deep" thinking, when in reality their own "critical thinking" skills wouldn't get them very far in an army boot camp, or a chess club, or a debating team, or any other environment which they aren't already well adapted to.

When most people say "learn critical thinking", they mean "get really good at it, like I am, so you don't get all bogged down by trivial details".
