Snow students under with lots and lots of instruction.
When you have handed out:
- a full page overall rubric
- an additional two pages or so of general tips with every essay
- a full page of typed comments
Students worry whether they missed something in there. Or, they think you are really persnickety and tough and are happy to have escaped with the grade they did.
I’m joking, really. I have no idea whether that’s why I get very few requests for higher grades. But I like to believe it. Best idea from others: make them write up a written justification that shows either where the handouts misled them or failed to mention a criticism received.
