My one gripe is the weekly nature of the blog grade. I feel that it encourages a negative mindset about blogging--saving up ideas. For example, "I have something really interesting that I could post to the blog right now, but I've already posted enough this week, so I should wait until next week instead of wasting it." This attitude is obviously dumb and harmful to the success of the blog, but still a hard one to fight off.
I'm not saying that I would have a better way of grading it...I wouldn't. Just sayin.
I'm still trying to find a good way of handling the blog grade. In previous semesters, there was only one grade for the entire semester's blogging, and WAY too many students ignored my "three posts a week" dictum and instead posted thirty-six times in the last two days of the class. I want to do something that demonstrates that I really value consistency of engagement with the blog.
But hey -- I'm open to suggestions, if you guys have any. If you were going to run a class with a blogging requirement, how would you structure it?
