Eh, once you get the pattern down it becomes almost a rote operation. Especially for a 2-3 page paper. You find 3-4 facts/arguments to support your conclusion and turn them into paragraphs. Slap on an intro & conclusion pre/re-stating your 3-4 points and you're done.
In my required college 1st year writing class I had to read a lot of my peers' writing. Most people have not learned how to do this. They do not understand the concept of stating a premise and then supporting it with evidence.
“Once you get the pattern down”, just like learning other subjects like math? But many kids don’t have it down. And there are gradations in complexity. An 8th grader who’s got it down and a 12 grader who’s got it down will produce different artifacts and should have different assignments.
