For most of us, there has been a topic or issue that we've struggled to teach, but were never quite satisfied with our success. For these situations, the Web has proven to be a remarkable resource. This is especially true when multimedia materials are involved because the Web is a very powerful delivery system. In addition to the many supplements being created by teachers for their own sites, there are numerous supplements being developed by commercial sources. Publishers provide sites intended to be used in conjunction with particular texts.
Software developers provide sites to support and extend their product's features.
If you are interested in supplementing your course with an online component to enrich your class, do a Web search before you create it. With the thousands of free online tutorials and animations that have been created by both educational and commercial entities, what you want may already exist. A quick Internet search for the supplementary material to help your students understand a particular concept may save you hours of work building your own. These pages were developed using crude software tools that were available prior to course management software packages. This site is rich with multimedia animations and images, and reflects the kind of instruction not available from a traditional text format.
