One obstacle stands in the way of most instructors. Most web processors can produce web pages as easily as word processed documents. Currently it is just a perception problem. Therefore instructors should think of this technology as just another tool for delivering instruction. It should and probably will become another necessary tool for teaching.
All instruction is delivered through one medium or another.
All mediums have their intrinsic advantages and disadvantages. And because different media have advantages and disadvantages, instruction should be designed differently based upon the media. They can lead a traditional classroom based course and still take advantage of the web. This is as opposed to a Web-delivered class. Students do not come to campus for this course and they generally only interact with their instructors via email or a web-based bulletin board system.
