Information architecture can provide a strong support to the instructional goals of problem-based learning environments by identifying and proposing optimal ways through which information can be organized and presented. The identification of optimal ...

This poster presents BioWorld (Lajoie et al., 1998), a computer-based learning environment (CBLE) that engages learners in realistic problem solving as they attempt to diagnose medical cases. Its design is consistent with both problem-based learning ...

Computer and network afford many features to support collaborative learning. These collaborative tools include visualization tools, such as content-specific and content-unspecific tools, argumentation, such as synchronous or asynchronous tools, and...

The purpose of this paper is to first briefly review ways in which the roles of computer and information technology have become important in teaching and learning today. This trend has also become increasingly apparent within the domain of...

This study was conducted to support the design of a prototype for a multimedia bilingual electronic dictionary. The purpose of this study was to examine the effects of the combination of verbal and graphic representations on the vocabulary...

We present three different approaches to the research and development (R&D) of information systems: problem solving, decision making, and case-based reasoning. In contrast to case-based reasoning, problem solving and decision making are rule-based...

Hypothesis generation is a fundamental step in diagnostic reasoning that requires specific cognitive support. We hypothesize that existing clinical reference tools are ineffective at supporting hypothesis generation because they can be searched by...

CoREAD, software that enables learners to collaborate indirectly while reading a text, was designed using a self-organising systems approach. Using CoREAD learners highlight portions of the text they deem important. The font colour of the text is...

This paper discusses an ongoing series of studies. An initial study of diagnostic problem solving in internal medicine involved medical students, residents, and experts solving a set of cases while thinking aloud. Verbal protocol data was used to...

This study presents an innovative medical case validation activity modeled on the case presentation practice commonly performed by physicians. Case development work for BioWorld (a computer-based learning environment) led us to note significant...

In this paper we discuss a type of social software that might be called social annotation. Such software enables individuals to add annotations – underlines and highlights, for example – while reading a text. Additionally, some aggregation of those...
