George,
Thanks you for providing input to several of these forums. I know others will benefit from your input.
You are right in that feedback should help students improve. Assessment should not be something we do to our students, but with our students. When you get the opportunity, include self- and peer evaluation as well.
As you noted, individualized assessment is important. And, the point about varying your feedback is great too. "That was good!" ;-)
Thank you.
