This study compared pattern notes generated by participants with word association hierarchies, which is the best current measure of cognitive structure, in order to investigate whether pattern notes could be used for cognitive mapping. The participants were 24 high school physics students. Results are interpreted and discussed. (Author/MT)

Description of expert system development focuses on identifying the problem, or knowledge, domain, and discusses three methods for defining the domain: (1) brainstorming, (2) concept analysis, and (3) information processing analysis, which describes cognitive processes. The techniques are illustrated by a description of an auto manfacturer's sales…

Compares the effects on the knowledge structure of the learners of using two different Mindtools--semantic networks and rule-based expert systems--for representing the content of a course. Results showed that students in the semantic network class possessed more hierarchical knowledge structures than the other group. (Contains 29 references.) (JLB)

Explores the utility of mental models as learning outcomes in using complex and situated learning environments. Describes two studies: one aimed at eliciting mental models in the heads of novice refrigeration technicians, and the other an ethnographic study eliciting knowledge and models within the community of experienced refrigeration…

Presents a conceptual foundation for using concept mapping as a cognitive learning strategy and as a method for assessing structural knowledge; reviews the growing body of research related to both applications. Describes some of the conceptual and empirical limitations of concept mapping. (Author/AEF)

Cognitive simulations are runnable computer programs for modeling human cognitive activities. A case study is reported where expert systems were used as a formalism for modeling metacognitive processes in a seminar. Building cognitive simulations engages intensive introspection, ownership and meaning making in learners who build them. (Author/AEF)

Hypertext is well-suited for educational applications where open learning and knowledge exploration is desired. In such applications, principles of good hypertext interface design should be employed to avoid navigational problems so as to maximize learning. Interface design, however, may also directly enhance acquisition of a particular knowledge…
