Hi Amy,
> the fact that the forum reports an average of the ratings to the gradebook rewards students who participate very little the same as students who participate a lot.
I quite agree. What I do is as follows. For each forum in a given course, I count the total number of new posts and the total number of replies posted by each student. Then in my favorite spreadsheet I have written a formula to compute a "forum grade" which takes into account a) the average grade for that forum taken from the gradebook, b) the number of new posts and c) the number of replies. The resulting grade takes into account both quantity and quality. However, because there is no reporting tool in Moodle to output data b) and c), I have to calculate the numbers by hand, going through each student's "complete report".
> it is difficult to teach students the inherent value in constructivist uses of technology...
Actually, one reason why I prefer to do the forums grading myself is that it is difficult to teach the students the criteria for judging their classmates' forum discussions (or their own). This is all the more difficult as my courses are English as a foreign language classes, where I have to evaluate the language used as well as the contents. So I end up wanting to assess 3 separate elements in the forumu discussions: the contents, the language used and quantity.
> What I've found is that the instructor has to be VERY active in the forum for it to really work.
Well, actually, I've found that it is often the opposite. I've noticed that - when some discussions work really work well between the students - any teacher intervention can easily put an end to the discussion. But of course it really depends how the teacher is active.

Thanks for making me learn a new expression.
And thanks everyone for a most interesting discussion.
