I strongly agree, but which writing textbooks, courses, or other material does the best job covering this material?
One exercise that I remember from school (though I can't place it to a particular year) involved writing instructions which another student would then follow to reconstruct a drawing.
The goal was to get the reader to draw out each letter of a message, but you weren't allowed to use the names of letters, and the reader didn't know the instructions were meant to make a message. So the instruction "draw a half-circle pointing left, with a line connecting its ends" might get you the capital letter D, or it might get you this.
Now that I think about it...
I was looking at a discussion of what should be in a college curriculum, and as such discussions seem to go, there was a big list of things everyone should study, and some political claims about what's being offered but shouldn't be.
Instead, what do you wish you'd studied in college? What do you wish other people had studied in college? On the latter, do you think everyone should have studied it, or do you just wish more people knew about it? Approximately what percentage of people?
Of course, this doesn't have to be limited to college. People could learn the same things earlier or later.
