When I introduced blogging to my high school physics students, they weren’t exactly ecstatic. I thought I had it all planned out perfectly. I outlined clear requirements. I had high expectations. At least once every two weeks, I asked them to post what they felt was the big idea for the unit we were studying — a reflection, a picture they took that demonstrated the concept, a link to a website that had more resources related to the unit or comments posted to blogs of other students.
