'We see this edition as continuing to offer helpful, research-based suggestions to teachers who would improve their teaching using the Web. The first edition of Web-Teaching was somewhat dated when it came off the press. This edition also shoots at a quickly moving target. Much has happened in four years. Little has happened, however, to modify the principal messages of the first edition. This edition attempts to focus reader attention on research reported from the early days of Web teaching.
There are six things we can say about Web teaching at this time:
1. Course Management Software (WebCT, CourseInfo) has emerged and been embraced strongly by teachers. As a result, the number of teachers whose courses have some Web presence is mushrooming. For our first edition, Web teachers who managed their own servers represented a large fraction of those using the Web. This no longer is so; today few teachers manage their own Web servers.
2. The first edition suggested that Web teaching might not be successful in certain content areas. It turns out that Web teaching can be applied to nearly any non-laboratory course in the curriculum. Even portions of some laboratory and studio courses have been handled well on the Web.
3. While extensive studies are not available, early results suggest that students in Web courses learn about the same amount as do students in traditional courses. Drop out rates in Web-based courses are higher than in traditional courses, but similar to other distance courses.
4. There have been no results that suggest strong learning gains from multimedia approaches to teaching. Thus far, it appears that media have small effects. Active learning approaches have larger positive effects on learning outcomes.
5. Many teachers have developed Web supplements for their courses. There is very strong evidence that the students who use these resources learn better than those who do not.
6. Very few teachers have enjoyed time efficiencies as the result of developing a Web presence. Quite the opposite; teachers find that Web courses take more time. This is especially true of courses involving discussion, where reading Internet-based discussions can become an enormous chore.'
