I think it's likely that kids are not taught outlining any more and I guess teaching cursive has disappeared. My 5th-grade teacher taught us to outline, first with written material, then with short lectures. Notes were turned in, corrected and graded. This continued, with increasing frequency and complexity, through 8th grade. In HS, we were expected to be able to take appropriate notes on our own. This was especially true for college prep classes, but US history was all juniors together and passing meant taking decent notes. I think we're at the point where kids expect study guides, reviews etc - not just in HS but in college, to the point of not being able to do without such aids. The real world doesn't work that way.
That is no longer the case. I've been a substitute for two years and what you wrote is how I was taught during my schooling in the 80's and 90's. I'm noticing there isn't any real instruction. In fact, there aren't any subjects being taught. And cursive writing, forget about it!! Hence, two generations of students have chicken scratch for penmanship, can barely read, and cannot retain anything beyond the last test/quiz.
