A heuristic for solving large-scale zero-one programming problems is provided. The heuristic is based on the modifications made by H. Crowder et al. (1983) to the standard branch-and-bound strategy. First, the initialization is modified. The modification is only useful if the objective function values for the continuous and the zero-one…

This paper suggests that it may be productive for all teachers to become students of metaphor, as least of their own metaphors. Careful attention of how one describes the world appears to give clues as to how one constructs it. Such constructions can come under scrutiny only when one speaks or writes, and then attends to the language one has used.…

An assignment given to students at the end of an advanced composition class empowers students by helping them grasp principles and develop abilities that allow them to get beyond needing teachers. The crux of the assignment is a heuristic for analyzing any particular type of writing for the purpose of learning to produce it. The students are…

A heuristic model designed to improve creative problem-solving by engineering students was studied. Ten students majoring in industrial engineering were pre-tested to establish the range and accuracy of their performance prior to training and to identify stereotyped thinking. The test was an adventure scenario with 50 embedded problems along with…

Discusses possibility of using expert systems to develop new model in cataloging theory made necessary by technological progress, rising user expectations, and economic pressures. A data structure for bibliographic information required by Anglo American Cataloging Rules, 2nd edition, (AACR2) is suggested, and possible heuristics for interpreting…

Applications to computer-assisted instruction, in which students are led through heuristic processes, are discussed. A greater impact can be expected on America's prose from word-processing software and from the use of the microcomputer as an instrument for writing rather than for the teaching of writing. (MLW)

This paper presents a research project conducted by the Department of Information Science in cooperation with the Saarland Museum, the art museum of the Federal State of Saarland, Germany. The study had two aims. The first was to evaluate some methods of usability engineering for the Web, and the second was to evaluate the usability of the…

Introduces three new metrics that measure the range of use of a university Web site by its peers through different heuristics for counting links targeted at its pages. Results from all three range models that were tested on United Kingdom university Web sites correlate significantly with the research productivity of the target institution.…

Assesses strategies employees use to express upward dissent within contemporary organizations. Indicates that employees used direct-factual appeal, repetition, solution presentation, circumvention, and threatening-resignation strategies for expressing upward dissent. Provides support for the exit-voice-loyalty model (and subsequent revisions) of…

Investigates using the microcomputer to develop a sentence parser to simulate intelligent conversation used in artificial intelligence applications. Compares the ability of LOGO and BASIC for this use. Lists and critiques several LOGO and BASIC parser programs. (MVL)

Explores how word processing affects thinking and writing. Examines two myths surrounding word processors and invention in technical writing. Describes how word processing can enhance invention through collaborative writing, templates, and on-screen outlining. (MM)

Describes a preliminary definition of engineering method as well as a definition and examples of engineering heuristics. After discussing some alternative definitions of the engineering method, a simplified definition of the engineering method is suggested. (YP)

Describes virtual reality (VR) technology and VR research on education and training. Focuses on immersion as the key added value of VR, analyzes cognitive variables connected to immersion, how it is generated in synthetic environments and its benefits. Discusses value of tracked, immersive visual displays over nonimmersive simulations. Contains 78…

Observation and interviews of (n=90) second and third graders' mathematical problem-solving behavior found that the children readily attempted unfamiliar problems and used systematic solution processes. Found no significant gender differences. (24 references) (Author/MKR)

Examines how problem solving in the domain of Mendelian genetics proceeds in situations where solvers' mental models are insufficient to solve problems at hand (model-revising problem solving). The study addressed the heuristics characteristic of successful model-revising problem solving and other aspects of student model use. (LZ)
