At Northern Illinois University, WAC teachers and consultants have compiled four useful ways to use "Writing to Focus Attention During Lectures." Visit http://www.engl.niu.edu/wac/. Click on Archives, "Ideas for using more writing," and "Using writing to focus attention."
This same WAC resource (WAC@NIU) has several linked items under Archives, "Ideas for Journals" that might be useful as you think about writing-to-learn activities in your classes. Be aware, though, that most of these links refer to journals not closely tied to course content. "Guidelines for using journals" has some helpful logistical points. "Reading journals" lists specific questions you might use with this kind of journal.
