Reports the results of a non-randomized study of 45 history Ph.D. students in England and discusses the results in terms of the theory of knowledge structure and the modification of knowledge structure due to information. Topics include information as process; a model of stages of the information process; and grounded theory. (Author/LRW)

The second of two linked articles develops two more mapping typologies: first, an approach to the what, why, and how of leaders, leading, and leadership; and second, the presentation of possible positions that knowledge workers can take when they use and produce knowledge about leadership practice. (Contains 10 notes and 73 references.) (MLF)

Method is presented for displaying the sequential and multirelational ideation of scientific narrative elicited from respondents. The flow map provides a figural representation of the flow of information, the points in the flow where multirelational and recurrent linkages are made, and the time required to retrieve and express the information at…

Verbal and nonverbal classification tasks were administered in Spanish and English to 30 bilingual children, aged 6-7. Results indicate the positive influence of bilingualism on cognitive development and support a model in which bilingual children construct two representational systems--one, nonverbal and universal across languages; and a second,…

Reviews recent research in the area of mathematical understanding and compares and contrasts it with a model formulated for the growth of understanding. Uses the analysis of a transcript from an interview with an eight-year-old boy to illustrate the power of the model to describe and map the growth of his mathematical understanding. (18…

Based on a two-tiered epistemological model (preliminary physical concepts and emerging mathematical concepts), studied the construction of number among 91 kindergarten students in France, Canada, and the United States. Subjects' cognitive numerical structures were surprisingly similar despite differences in language and culture. (SV)

Described is research which sought to prove the hypothesis that mental models tend to preserve their autonomy with regard to the originals they are meant to represent. The results of this investigation involving 200 Israeli students are presented. (CW)

Shows how box diagrams and AVOW diagrams may be used to solve problems concerning networks of resistors that obey Ohm's Law. Presents outcomes and feedback from students and teachers. Concludes with suggestions as to how these techniques might be incorporated into the teaching of basic circuit theory. (Contains 22 references.) (DDR)

Advocates artificial neural networks as models for cognition and development. Provides an example of how such models work in the context of a well-known Piagetian developmental task and school science activity: balance beam problems. (Contains 59 references.) (Author/WRM)

Purpose: The purpose of this paper is to propose a model for holistic professional development as an alternative to practices that have been piecemeal and curriculum focused ignoring, in particular, the critical dimension of management development. Design/methodology/approach: A conceptual framework for considering professional development needs…

Recent federal initiatives and efforts within education and psychology professional organizations have contributed to an increased focus on scientifically based practices in education. Although interventions are available to educators, there is a need to enhance systems capacity through identification, selection, and implementation of appropriate…

Chemistry is commonly portrayed at three different levels of representation--macroscopic, submicroscopic and symbolic--that combine to enrich the explanations of chemical concepts. In this article, we examine the use of submicroscopic and symbolic representations in chemical explanations and ascertain how they provide meaning. Of specific interest…

The pursuit of a science of mind has been marked by persistent conceptual tension. At one pole, exemplified by Piaget, the mind is characterized in terms of overarching principles. At the other end of the continuum, theory is more concerned with modeling particulars, as represented by the information processing model. This paper explores the…

This study applied previously identified cognitive theory and research to the development of an instructional design model for teaching mental aspects underlying work and family activities in a context of rapid change and high technology. The model was tested by developing a prototype, materials required by the prototype were developed, and the…

The purpose of this study was to investigate the effect of an eclectic thinking processes model on the logical reasoning abilities of students in grades six through twelve. The experimental school consisted of 159 students whereas the control school had 111 students. The Group Assessment of Logical Thinking (GALT) was administered to the sample as…
