In this paper we consider prior definitions of the terms "ill-defined domain" and "ill-defined problem". We then present alternate definitions that better support research at the intersection of Artificial Intelligence and Education. In our view both problems and domains are ill-defined when essential concepts, relations, or criteria are un- or…

Recent progress in wireless and sensor technologies has lead to a new development of learning environments, called context-aware ubiquitous learning environment, which is able to sense the situation of learners and provide adaptive supports. Many researchers have been investigating the development of such new learning environments; nevertheless,…

Defines the concepts of hypertext, hypermedia, multimedia, and multimedia networks. Using the rhizome as a metaphor for electronically mediated exchange, a theory of hypermedia design that incorporates principles of connection and heterogeneity, multiplicity, asignifying rupture, and cartography and decalomania is explored.

Discusses the problem of establishing terminology for mental models, attempts to sort out the various meanings found in the literature, and offers definitions that could help in developing a more standardized terminology for discussing issues of concern to researchers in human-computer interaction. The role of mental models in learning and using…

A computer system, IconiCase, is currently being developed to assist users in the task of classifying and memorizing medical cases. The system uses assemblies of icons, called Concept Graphics (CG), as pointers to medical cases, leading to a form of electronic document delivery in which information is accessed at various levels, with a gradual…

This paper reports recent work in developing of structures and processes that support university teachers and instructional designers incorporating learning objects into higher education focused learning designs. The aim of the project is to develop a framework to guide the design and implementation of high quality learning experiences. This…
