Do we communicate more with students in writing than we used to? I think so. In addition to the course syllabus, the usual handouts, and written feedback on papers, projects, and performances, we now share all kinds of electronic messages with students. We exchange emails, post announcements on course management systems, and participate in online discussions. Those who use PowerPoint tend to make rather text-heavy slides. And if you happen to teach online, then virtually all your communication with students occurs via some written format.
