Computer mediated learning (CML) courses can overcome the temporal and spatial obstacles of isolated commuter students with busy schedules. Whether presented online or as an add-on to an on-campus course, the CML course needs a good syllabus. This paper discusses components of a CML syllabus and online activities for students. Typical components of a regular class syllabus are defined, as well as possible unique or modified components of a CML syllabus. Components include course advertising, "how to use this syllabus," table of contents or course map, contact information, required textbooks and other materials, examinations, grading procedures, provisions for disabled students, activities that encourage students to use technology, student roster, tutorials, and an idea sharing segment (listserv, chat room, bulletin board). Web sites with expanded descriptions and additional syllabus components are listed. The use of hypertext links to other web sites can build the syllabus into an expanded student resource. The syllabus could be linked to information sources, a homework page, home pages of faculty and students, collections of solved problems, references works, class archives, videotaped or animated demonstrations, and a page for student notes on electronic materials or course feedback. When beginning a CML course, first activities include introducing participants, explaining net etiquette, introducing site maps, pairing novices with more experienced learners, and clarifying expectations. Online teaching tips and additional student activities are recommended. Contains web site references. (SV)
