You make great points. One, that we have to remember is that we start with the student not with the technology which is the focus of Gagn, Briggs & Wager, 1992 (Palloff and Pratt) and most certainly Knowles. Second, we have to begin teaching are students to read, accept, and use feedback. A grade and feedback are not the same!
FYI, I love the detail in which you post. This is a great example of a well articulated, discussion posting. Nice job!
