I wish this had been taught week 1 of college when I went in the mid 90s. All college's should have a mandatory module on note taking, learning techniques and general planning and productivity.
I'd also add general theory of education content to that. How do we expect people to learn if they don't understand teaching?
Most of the colleges I'm familiar with have "college success" courses that purport to teach things like this. I took one. I recall not paying much attention to it because it was in addition to my normal course load.
Not so sure about mandatory. A system like this is pretty useless unless you’re motivated to use it. How much benefit would the students taking the module only because it’s required really see?
These study techniques ought to be introduced even earlier like during middle school grades. Time management and information processing are key to a successful educational experience. The fact that this is not generally taught is a major deficiency in most schools.
