This discussion of the utilization by computer designers and users of metaphors as organizing structures for dealing with the complexity of behavior of human/computer interfaces begins by identifying three types of metaphor that describe various aspects of human-computer interface design, i.e., activity, mode of interaction, and task domain. The…

The paper discusses problems with traditional definitions of dyslexia and reviews research that suggests a more comprehensive definition, viewing dyslexia as a developmental language disorder that involves a deficit in phonological processing. The disorder is seen as manifesting itself in various phonological difficulties as well as in a specific…

This essay, the concluding section of a larger study, examines the present state of cognitive science and instructional theory as reflected in the study's earlier chapters. Cognitive analyses of tasks are reported in the broad domain of language comprehension and production (e.g., understanding, composing, and answering questions about texts). The…

As an introducation to a symposium on curricular innovation, a sociolinguistic perspective is used to tie together presentations to follow on collaborative and deliberative processes in pedagogy, research, and evaluation in school settings. Collaboration and deliberation, as processes, are bound by the same constraints and potentials inherent in…

Noting that although a great deal of empirical research has been done to investigate the writing rules commonly taught, this paper points out that no one has yet constructed a deep theory of the relationship between cognition and writing that confirms the writing rules and explains how they work. The paper then uses theories and research in the…

The two papers in this compilation were drawn from a conference designed to encourage scholars to continue the rhetorical tradition. The first paper, delivered by Todd Sorenson and Carrie Stopek, was the paper most highly commended by a panel of critics at the conference. The paper uses fantasy theme analysis, specifically the three fantasy theme…

This set of five papers, written in German with abstracts in English, was collected by the Institut fuer Didaktit der Mathematik (Institute for the Teaching of Mathematics) at the University of Bielefeld in West Germany. In the first paper, Bauersfeld used a transcript of a videotaped scene of group work out of school as a basis for analyzing…

Presents an algorithm for use in natural language document retrieval systems which automatically determines if the conjunction "and" in a statement representing an information need should be translated into a Boolean "and" or "or." The results of an experiment that used the algorithm are reported, and further research is suggested. (CLB)

Describes a system developed for the automatic recognition of biological concepts in titles of scientific articles; reports results of several pilot experiments which tested the system's performance; analyzes typical ambiguity problems encountered by the system; describes a disambiguation technique that was developed; and discusses future plans…

Language is a complex social event. The rules determining its use vary with (1) the language field--the subject, text, and purpose; (2) the tenor of the social interaction; and (3) the mode or type of communication being used. The impact of the field, tenor, and mode on language use is reflected in a college student's retelling of a story to a…

Advances in cognitive science have greatly increased our knowledge of how the human mind stores and uses information. That knowledge can be used to decompose curricular objectives so as to increase the specificity of instruction to a level of precision that should greatly enhance student writing. This article identifies some major types of…

This set of five papers, written in German with abstracts in English, was collected by the Institut fuer Didaktit der Mathematik (Institute for the Teaching of Mathematics) at the University of Bielefeld in West Germany. In the first paper, Bauersfeld considers domains of subjective experiences as the best issue for an interactive theory of…
