A visual language system for developing and presenting Internet-based education

The paper describes a visual language for organizing educational materials to be published on the World Wide Web using the Collaborative Multimedia Instructional Toolkit (CoMMIT). The developer uses the visual language to create a precedence graph that defines the organizational structure of the materials. This graph specifies materials that must be viewed as prerequisites for viewing other materials. This provides significantly more flexibility than existing path based educational authoring systems or hypertext link based HTML editors. Additional icons representing questions and advice supplement the precedence graph to provide educational support.
