    Hi Allison, Thank you for the additional suggestions. Personal connections really are important in a virtual classroom. That is a very noteworthy point! Best, Beth

    Those ideas are great-- thanks.

    A few additions.

    -- To increase value and appreciation of the rubric, provide an example or two, linking the rubric elements to the instances. They love that-- and for good reason.

    -- Send out a weekly letter that reminds of what was recently accomplished/covered, what is expected over the next few weeks, and pointing to particularly useful resources. I also include some slightly personal news, such as a trip or life event. I have congratulated a student on the birth of a baby, for example, and urged the student to post a picture. When teaching an online class during San Diego's dreadful 2004 wild fires, I spoke of them and how they were affecting us. It's a good way to keep students up to date and to remind them that this online class is peopled with human beings, emphasis on the human.

    I think this is a good warning that online courses should be carefully prepared. Gary was too much concentrated of how will he does the course insted of thinking what can he learn.

    This article really makes you stop and think - at what point does technology go from being a benefit to being a barrier?
