Describes a computer-based methodology for representing mental models as maps, extracting these maps from written and spoken texts, and analyzing and comparing concepts and structures of information within maps. Illustrates the model using data on students and teacher in an undergraduate writing class. Contains about 80 references. (Author/SV)

Proposes a model for the growth of mathematical understanding based on the consideration of understanding as a whole, dynamic, leveled but nonlinear process. Illustrates the model using the concept of fractions. How to map the growth of understanding is explained in detail. (Contains 26 references.) (MKR)

New methods for representing the structural properties of domain-specific knowledge were studied. Network representations of data from 40 college students' ratings of the relatedness of domain concepts were derived using the Pathfinder scaling algorithm, and similarity between students' and instructor's networks was then assessed using a…

Discusses communication in research and development, hypotheses of efficiency, and implications for information science. Topics addressed include cognitive situations of individuals and groups; the use of information; the adequacy of available information; the inefficiency of scientific communication; and the unpredictable impact of the same…

Focuses on cognitive and affective changes that occurred in one student during the study of heat and temperature. Initially the student's conceptual framework was undifferentiated with regard to heat and temperature; however, course activities and concomitant use of concept substitution helped the student differentiate these concepts and integrate…

Presents evidence indicating that spontaneously generated analogies can play a significant role in expert problem solving. Focuses on an evaluation strategy known as bridging that has been observed in solutions to both science and mathematics problems. Contains 23 references. (DDR)

Explores the notion that some social interactions are more conducive to the construction of knowledge than others. Describes the use of argumentation as a learning tool during play by analyzing transcripts of the interactions of four-and-a-half year olds. Derives implications for early childhood education from these examples and from a theoretical…

Investigated intervention effects on mental models of multivariable causality in middle school students involved in inquiry learning. Found that inquiry learning promoted a correct mental model based on additive effects of individual features and a meta-strategic understanding of the need to control influences of other features. Also found…

The performance of 32 undergraduates (aged 17-27 years) on a map task show that interactive style influences choices of forms of introduction. Assumptions about shared knowledge and prior task experience also influenced choices. (Contains 30 references.) (JA)

Assesses the understanding that a sample of Oregon public school students (n=159) had of geology, physical and chemical characteristics, ecology, and natural resources as related to a marine environment. Results indicate that student understanding in some areas does not progress beyond the early grades and that the interdisciplinary approach of…

An appreciation of the relationship between novice and expert knowledge frameworks may help develop an understanding of the process of transition from one to the other. Recommends the use of concept mapping. (DDR)

Describes a study of Taiwanese 14-year-olds' (n=48) cognitive structures derived from the instruction of basic atomic physics. Finds that even academically above-average students tended to use relatively lower-level modes of knowledge construction, focusing on reciting or describing specific factual knowledge in physics. (Contains 27 references.)…

Uses a video presentation of six situations relating to the evaporation and boiling of liquids and the escape of dissolved gases from solution and investigates graduate scientists' understanding of the concepts of boiling and evaporation. (Author/YDS)

Reports on a study of the relationship between written content and its illustration. Also explores the problem of image comprehension. The study involved students (n=78) in a teacher training course. Concludes that very strong inducements to attract attention to illustration must be included in the text. (Contains 35 references.) (DDR)

Examines third year university physics students' use of models when explaining familiar phenomena involving interaction between metals and electromagnetic radiation. Concludes that few students use a single model consistently. (Contains 27 references.) (DDR)
