The real problem seems to be with the testing and grading system, and the fact that some people game them to receive some title or other credentials. If one is really interested in learning to write well, or to understand what good writing is, then this particular teacher might still have liked their job. That approach probably doesn't make much money though.
I don't know. When have you heard a single student or educator in a class suggest, "All submitted papers should be available to be read by everyone in the class"? Think deeply about the impacts of that. Other than a creative writing class, I can't recall a single time when I could read someone else's papers without their express permission. I'm bringing this up because you're talking about a tired trope, that making…
I gave it a shot, but I wasn't able to get very deep about it in the first place. I couldn't even begin to come up with any ideas of what could really go wrong if everyone's papers could be freely read by the rest of the class. I couldn't read someone else's papers either, but this was generally because there was no motivation to go to the trouble of gaining access to them, not because it would have been wholly unacceptable.
Maybe I'm just tired, but I think I'm not really grasping how this whole thing follows from / connects to the parent, or within itself; you might have to spoonfeed or state the seemingly obvious or something
