In addition, the tools include automatic grading feedback on homework and birds-eye views of pages so that students can see where they are in the material and find other information more quickly. Comparison with Other Instructional Models Non Web-based distance learning models have relied on videotapes and broadcasts. While some Web courses have been taught synchronously via White Boards, etc., the technology just isn't sufficient yet. Our model is primarily asynchronous, allowing both the instructor and students to work at their own place, rate, and time. Most Web-based courses are created and maintained by the instructors, perhaps with TA help.
Few systems exist to aid the teaching of Web courses.
Web courses take a phenomenal amount of time to develop, update and maintain. Tools to reuse material are needed. We know of no other system that addresses this retargeting issue. During the preceding three summers, we have collected statistics on time spent by both students and the instructor. This is the first year that all the tools will be available.
