The cognitive structure of 13 concepts in pulmonary physiology was explored among 112 first-year medical students and among 32 faculty members in three different expertise groups in a knowledge representation study. Purposes were to assess the degree of agreement among faculty members, map students' concept structures, and compare the similarity…

The Department of Administrative and Policy Studies (APS), University of Pittsburgh (Pennsylvania), completed six research reports about its Conceptual Mapping Project. The reports reproduced here originally appeared in the "Occasional Paper Series" of the APS. They are presented in order of the chronological appearance as follows: (1)…

The development of cognitive representation is the main theme of three classic theories (Piaget, Bruner, Vygotsky) on how children learn concepts. Piaget considered structural change as a necessary condition for development; Bruner emphasized both internal and external function and the structural changes brought about by function; and Vygotsky…

Schemas are cognitive structures or forms of thought, like pieces of ideas or concepts. Patterns in children's behavior, or in their drawings and paintings, indicate common themes or threads (schemas) running through them. The action research study described in this report examined the effects on children's learning of intervening in their…

The present study was an exploratory study of the content-specific knowledge structures of three teacher educators (two in math and one in science). Pathfinder, a method for eliciting associative memory networks, was used to describe the knowledge structures of the teacher educators. Pathfinder was also used to determine changes in knowledge…

Three different theory of mind tasks were conducted with 4- to 8-year-old Quechua peasant children in the Peruvian Andes. The study investigated the ways in which children in preliterate cultures think and the possibility that they think differently than children in literate cultures. The tasks included: (1) a false-belief task, which tested the…

This paper explores the nature of content and language across the curriculum in relation to the Targets and Target-Related Assessment (TTRA) initiative. The TTRA is an assessment initiative designed to improve the quality of individual learning from Primary 1 to Secondary 5 in Chinese, English, and Mathematics in Hong Kong. A picture of content…

The development and role of subject matter knowledge within teachers' professional development is currently the source of much research; however, the parallel development and role of pedagogical knowledge has yet to be systematically analyzed. In investigating this seldomly tapped area of concern, researchers involved 26 preservice science…

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…

The first of two parts in this document is a student workbook which is designed to teach students how to construct a concept map, i.e., a graphic arrangement of the key concepts in a body of subject matter with connecting lines labelled to show valid and meaningful relationships between the chosen concepts. The workbook provides a discussion of…

This paper presents preliminary results of research founded on the hypothesis that in real environments there exist regularities that can be idealized as mathematical structures that are simple enough to be analyzed. The author considered three steps in analyzing the encoding of modularity of the environment. First, a general information…

Maurice Merleau-Ponty's philosophy offers an existential phenomenological interpretation of subjectivity and the shared world. He offers a perceptually based philosophy which can be mined for implications and interpretations for a new style of teaching relevant to the contemporary social and educational scene. This paper analyzes Merleau-Ponty's…

To investigate the hypothesis that cognitive rules govern writing behavior, Carter's signaled stopping technique was used to study language and cognitive effects in public relations messages. Principles from Grunig, et al (1985) Axiomatic Theory of Cognition and Writing, which proposed premises, axioms and definitions about writing, were applied…

The conceptions of information needs of seven American and seven Swedish mechanics employed by a Swedish multinational machine industry are compared by using perspective text analysis to analyze their verbal responses to three open-ended questions concerning their need for work-related information. The structures embedded in the texts are…

Designed to focus attention on the design process in such computer science activities as information systems design, database design, and expert systems design, this paper examines three main phases of the design process: understanding the context of the problem, identifying the problem, and finding a solution. The processes that these phases…
