Your instructors will probably expect you to communicate both in and out of class using a variety of media. You may be asked to post to course management systems, lists, blogs, and wikis, and you may respond to the work of others on such sites. In addition, you will probably contact your instructor and classmates using email and text messages. Because electronic communication is so common, it’s easy to fall into the habit of writing very informally. If you forget to adjust style and voice for different occasions and readers, you may undermine your own intentions.
