Hi Dave,
I think you have raised some important points on on-line discussion (Elluminate), forum and blogs postings etc. and found them very useful.
I have created a response post on my blog: http://suifaijohnmak.wordpress.com
As I am not registered in your class, I have not fully understood the issues your class is facing. I could only relate to the CCK08 that I have attended, for the sharing of views
What are the general views of students of your class? Are they all different? Is digital identity an issue in your “closed class”?
Cheers.
