Found that in an introductory biology course at the University of Massachusetts Amherst, adoption of the Data Aggregation Project (free software that allows students in a course to aggregate a large body of data for some particular problem) resulted in an increase in the number of data points students analyzed per semester by a factor of almost…

Evaluates the scaffold designed as a dynamic modeling software tool called Model-It in terms of its ability to support learners' use of modeling practices. Discusses the continued empirical validation of types and instances of tool scaffolds. (Contains 50 references.) (Author/YDS)

Describes the importance of statistical reasoning in understanding modern science and critically evaluating information. Uses spreadsheet programs and the black box approach to teach basic concepts of statistical reasoning. Presents examples of the role of statistical thinking in the disciplines of biology, chemistry, physics, and geology.…

Four grammar checkers, all of French Canadian origin, were evaluated: "Le Correcteur 101,""GramR,""Hugo Plus," and "French Proofing Tools." Results indicate that "Le Correcteur 101" is the best French grammar checker on the market and worth its premium cost. (two references) (CK)

Proposes and illustrates a method of identifying key words in text, and leads from this proposal to the notion of key key words (words that are key in many texts). Notes that a key key word has associates: words that are key in the same texts as a given key key word. Notes that these associates can be grouped together in clumps. (18 references)…

From 1988 to 1996, employment in high-technology industries shifted toward services. Growth in these industries accounted for all of the net increase in research and development employment in the United States. (SK)

Discusses the use of a dynamic geometry software package to improve teaching of graph theory in basic graph sketching and in isomorphic, bipartite, and planar graphs. (JRH)

Examines screen capture, the technique of transferring an on-screen image or monitor display to a text or graphics file using a built-in utility feature or specialized software. Discusses uses of screen captures; kinds, sources, common, and uncommon features of software; and the simplest ways to screen capture on Macs and Windows-based computers.…

Describes a collection of systematic theory-based analyses of a system prototype that inherited its control mechanisms from preexisting systems. Demonstrates that collective use of system and user modeling techniques provides insight into a complex design problem, enabling the examination of design decisions for users and implementation. Discusses…

Provides an applications-oriented view of algorithmic historiography and how it relates to understanding scientific paradigms. Discusses HistCite[TM], a program that allows scholars to identify significant works on a given topic; paradigm shifts; a genealogic approach; citation analyses; correcting variations in citations; and bibliographic…
