Althouse thinks maybe not:

There’s a certain sort of teacher who’s always imagining stimulating the students to new levels of passion. I suspect students can find this quite annoying and burdensome. Not only does the student have to write a lot, he’s supposed to be allexcited about it. Because teacher says blogging is exciting. But the blog can be a slog. It’s not a slog for me, because I’m motivated from within. I make my own projects and do what I want. The intrinsic reward is fantastic. But I don’t imagine that I could make students feel the same thing if they have to write when and where I tell them to and submit to my judgment for a grade.
