Some of you may already read Tomorrow's Professor (a blog run by MIT and Stanford to discuss issues in higher education). If not, I encourage you to check it out!
If you use journals in your courses, you might be interested in TP's recent discussion of the subject. The author explains the benefit of student journals -- they get students actively reflecting on their reading for your courses--but provides some creative solutions to the problems journals pose (i.e., the feeling that you have to grade and comment on them). I know I might be making some revisions to my journaling policy based on this article.
