With the exception of the links that I have put on the page, most of what I have done online could be done on paper. If the web is to have a significant positive impact on student learning, I think it must do more than what could be done via the photocopy machine. I can imagine a number of ways in which this might be accomplished. Web materials could be made more interesting and attention-getting than their paper counterparts. Color is cheaper to use on the web, for example.
Web pages can be more image-rich.
Web pages can be linked to internal and external resources. Another potential advantage of the computer and the web is the ability to interact with users. In my limited exploration of class-related web materials, however, I find little that is really interactive. At present, the effort required to construct good interactive material is probably what keeps most class-related sites relatively passive. Of course, using the web has a few disadvantages.
