Yes, good points, Kristin. There are obvious differences in connectivity that would really challenge some teachers. I know myself that I am connected to various groups of students and colleagues all day and night. There are ways of still managing that, however, so that you can still "have a life"!! I do think, though, that the idea of "office hours" whether actual or virtual seem unnecessary and it is more a question of personal management than anything else. What ideas do you have for managing student access for yourself?
