Co-authors Stephen Valentine, a finalist in this year's
T&L Ed Tech Leaders of the Year program, and Gray Smith write about
this challenge in Writing in a Wired World: Improving Student Writing
Using a Computer, forthcoming from Teacher Created Materials. To
encourage substantive discussion in student message board
communication, they've developed conversation assessments using a
five-point rubric that outlines the key criteria for determining a
student's grade, including use of evidence, engagement with the text,
and whether or not a student responded thoughtfully.
