Blogging and using Primary Sources

Recently, I was able to assist a teacher with a project that involved the use of multiple primary sources. The teacher downloaded a variety of primary sources to his own eboard. The documents consist of video clips, photos, recorded conversations, etc. The assignment was posted on an inote. The students will be provided with an opportunity to reflect on each of the primary sources on a common discussion thread. I thought this was an excellent example of a constructivist approach to instruction.

I am interested in know how other people have used blogging to enhance instruction.
