true.... however, I had a professor during my masters ... 1s one actually... he would grade it - show where the corrections needed to be - return it - it was up to me to fix it all - make it better - he would grade it again and improve my over all score... as time went on, I got better and the errors lowered...
So- I did the adjunct professor thing for 2 universities and did the same thing for extra money — most students thought this was an excellent idea - other, thought their papers were A+ right out of the gate... a few others did 1 correction or 2 but that was it — if they walked with a C or B- — that was fine to them... The babies were the ones that wanted to write crap - turn it in and think what the wrote satisfied the requirement. When told no — they actually went crazy... I did that for 1.5 yrs and left the whole behind me... wasn’t worth it - or the pay...
I was also an underpaid adjunct for an online class. A MUCH better paying consulting job came up at a community college. To survive I had the students create an outline of each chapter. For the online discussion they each had to create 3 questions, answer questions of 2 different students, and respond to all answers to their questions. It worked extremely well. There was better student involvement, they had to actually think a bit, and my involvement dropped to near zero. An instructional design colleague thought it brilliant. There first year I used hours reviewing each weeks homework.
