Abstract

Altered Vista is an instructional system that supports a form of "contextual" collaborative learning. Its design incorporates an information filtering technique, called collaborative information filtering, which through computational and statistical means, leverages the work of individuals to benefit a group of users. Altered Vista is designed to provide, upon request, personalized recommendations of web sites. It can also provide recommendations of like-minded people, thus setting the stage for future collaboration and communication. An empirical study involving inservice and preservice teachers was conducted using Altered Vista and presents results from an empirical study. The study examined the feasibility and utility of automating the well-known social feature of propagating word-of-mouth opinions within educational settings. It also examined the impact of Altered Vista's ability to recommend a social network of potentially unknown people.
