This report describes a program for increasing students' ability to simplify square roots. The targeted population consisted of high school students in a rural community in a midwestern plains state. The problem of the ability to understand the abstract algebraic process of simplifying square roots was documented through teacher-made tests,…

In agreement with prior studies, syntactic order produced better recall, and recall errors were semantically related to the narrative. The more vivid versions of the paragraphs produced higher recall suggesting that imagery may play a role in recall. (Authors)

Examples are given of the usefulness of mathematics in several different fields. (MM)

The present study found that 6-year-old children made fewer errors on a recognition test of visual memory than did 5-year-olds. Sex and IQ differences did not appear to be related significantly to the child's visual memory ability. (Author)

Discusses the roles of visual thinking, visual rehearsal, and introspection in educational technology, and suggests that instructional designers should externalize their internal representations and involve the internal and external representations of content specialists and learners in the instructional design. Fifteen references are listed. (MBR)

Research fronts, defined as clusters of documents that tend to cite a fixed, time invariant set of base documents, are plotted as time lines for visualization and exploration. Illustrates the construction, exploration, and interpretation of time lines for identifying and visualizing temporal changes in research activity through journal articles.…

Discussion of knowledge domain visualization focuses on practical issues concerning modeling and visualizing scientific revolutions. Studies growth patterns of specialties derived from citation and cocitation data on string theory in physics, using the general framework of Thomas Kuhn's structure of scientific revolutions. (Author/LRW)

Describes an information retrieval, visualization, and manipulation model which offers the user multiple ways to exploit the retrieval set, based on weighted query terms, via an interactive interface. Outlines the mathematical model and describes an information retrieval application built on the model to search structured and full-text files.…

Investigates an integrated approach to scientometrics, or science mapping, with emphasis on the use of information visualization and animation techniques. Describes citation and cocitation patterns derived from articles published in the journal "Scientometrics", 1981-2001 and presents the growth of citation rates through an animation…

Examined whether variations in performance of (n=396) engineering students on a measure of spatial visualization were related to prior spatial experiences and to the developmental period when the prior experiences occurred. One finding revealed nonacademic activities seemed to have the most positive significant relationship to spatial…

This article examines the state of knowledge on the creative process, especially mathematical-scientific, verbal, musical, and artistic imagery. A creative imagination imagery model is proposed which has three major dimensions: the environment, the individual (with both content and process components considered in terms of the Structure of…

Finds that performance visualization is more effective in reducing communication anxiety, state communication anxiety, negative thoughts, and rigidity for people who can create vivid mental images than for those whose images are less vivid. (SR)
