Abstract: The World Wide Web has huge potential as a medium for learn<strong>in</strong>g, both <strong>in</strong> and<br />

out of classrooms. As more and more schools obta<strong>in</strong> access to the <strong>in</strong>ternet, learners<br />

(<strong>in</strong>clud<strong>in</strong>g parents, teachers, and students) are realiz<strong>in</strong>g that the web is not particularly useful<br />

for substantial educational use <strong>in</strong> it's raw form. This is primarily due to the lack of<br />

collaborative knowledge-construction facilities <strong>in</strong>tegrated <strong>in</strong>to the web framework as well as<br />

the lack of guid<strong>in</strong>g structure and dynamic management of l<strong>in</strong>k and nodes. This paper<br />

outl<strong>in</strong>es the hurdles one faces <strong>in</strong> us<strong>in</strong>g the web for learn<strong>in</strong>g, specifically <strong>in</strong> a collaborative<br />

knowledge-construction environment. It then suggests some theoretical solutions based<br />

directly on exist<strong>in</strong>g web environments, as well as on research and system prototypes <strong>in</strong> the<br />

areas of Intelligent Tutor<strong>in</strong>g Systems (ITS) and ITS author<strong>in</strong>g systems.<br />

Education for the 21st century -- Global issues grounded <strong>in</strong> the local community<br />

"The more th<strong>in</strong>gs change, the more th<strong>in</strong>gs stay the same." In a February 1996 <strong>in</strong>terview with Wired magaz<strong>in</strong>e,<br />

Steve Jobs commented that when one looks at the big picture, computers haven't changed the fundamentals of<br />

what life is about, "We're born, we live for a brief <strong>in</strong>stant die. It's been happen<strong>in</strong>g for a long time. Technology<br />

is not chang<strong>in</strong>g it much, if at all." [Wolf 1996] This is a powerful statement com<strong>in</strong>g from Jobs, who, <strong>in</strong> a<br />

previous <strong>in</strong>carnation as the co-founder of Apple computer, made it his mission to revolutionize education by<br />

br<strong>in</strong>g<strong>in</strong>g Apple computers to classrooms around the United States. Regardless of Jobs' credentials, the<br />

comment does r<strong>in</strong>g true, and we see it <strong>in</strong> our school systems as we struggle to make use of the excit<strong>in</strong>g new<br />

world of the World Wide Web. The computer and communication technologies <strong>in</strong> general have changed<br />

th<strong>in</strong>gs <strong>in</strong> the world of *work*, but we still struggle to f<strong>in</strong>d an important role for them <strong>in</strong> improv<strong>in</strong>g education.<br />

In<strong>format</strong>ion technologies -- writ<strong>in</strong>g, the pr<strong>in</strong>t<strong>in</strong>g press, and onward... -- have brought a never-end<strong>in</strong>g <strong>in</strong>crease<br />

<strong>in</strong> the amount of <strong>in</strong><strong>format</strong>ion available to the general world population. And while this flow of <strong>in</strong><strong>format</strong>ion<br />

has proven to be useful <strong>in</strong> the workplace to those that have already ga<strong>in</strong>ed the skills needed to filter through<br />

this <strong>in</strong>fortmation, they have not, with the exception of writ<strong>in</strong>g, improved the overall level of education of the<br />

population. This is not to say that artifacts such as television and computers can't be useful as educational<br />

tools, it is just that currently, there negative effects far outweigh their positive effects [Mander 1991]. Also,<br />

many argue that the "medium is the message" [McLuhan 1964] and that television is doomed to have also have<br />

a net negative impact on society [Postman 1992]. However, with the web, the situation is more hopeful. The<br />

World Wide Web has <strong>in</strong>creased the amount of <strong>in</strong><strong>format</strong>ion a person has easy access to, but it has done noth<strong>in</strong>g<br />

to aid the <strong>in</strong>dividual <strong>in</strong> deal<strong>in</strong>g with this <strong>in</strong><strong>format</strong>ion. In fact, like television, it often <strong>in</strong>flicts the <strong>in</strong>dividual<br />

with a feel<strong>in</strong>g of passive submission. Informed, but <strong>in</strong>active. This is evidenced by the small number of<br />

personal home pages and the even smaller number of those with any content other than l<strong>in</strong>ks.<br />

The web was orig<strong>in</strong>ally designed by Tim Berners-Lee as a medium for active widespread publish<strong>in</strong>g and<br />

collaboration between researchers, not as the one-to-many "tv-like" medium with the occasional list of a<br />

person's "favorite channels" that is most common today. [Berners-Lee, et al 1994] This situation probably<br />

developed for many reasons, <strong>in</strong>clud<strong>in</strong>g the difficulty of creat<strong>in</strong>g web pages directly us<strong>in</strong>g HTML, and the fact<br />

that the server and client-side mechanisms for provid<strong>in</strong>g for at least some form of collaboration, group<br />

annotations, was only implemented <strong>in</strong> a limited form (personal and local-group annotiations, but not public<br />

annotations) by the NSCA Mosaic team at UIUC <strong>in</strong> 1993. [Annotations]<br />

Instead of a new tool for provid<strong>in</strong>g <strong>in</strong>terest<strong>in</strong>g new ways for manag<strong>in</strong>g <strong>in</strong><strong>format</strong>ion and publish<strong>in</strong>g on one's<br />

own, we are left with a tool that has been responsible for over-extend<strong>in</strong>g our abilities to make sense of the
