There are many uses for the shortest path algorithm presented which are limited only by our ability to recognize when a problem may be converted into the shortest path in a graph representation. (Author/TG)

Explores the state-of-the-art of Japanese information activities, detailing the comprehensive national plan Japan has developed. The volume of scientific and technological publications is discussed: monographs and technical reports briefly, and periodicals in more depth, including subject areas, language of publication, and accessibility to…

Four different types of problems from graph theory are presented and discussed. (MK)

Random samples of monographic materials from U.S. and Canadian public libraries were matched with collections from similar libraries of different sizes. Strong positive correlation appears between percentage find rate and target library size, with regression analysis suggesting linearity over a wide range of collection sizes. (Author)

This experiment designed for beginning physics students, is related to postal regulations restricting the size of envelopes. A graph is constructed that allows for testing the mailability of envelopes. (MP)

This discussion of ways to use spirolaterals in the classroom includes making conjectures, hypotheses testing, and proofs, as well as a number of examples. (MP)

Suggests that before secondary principals can deal effectively with discipline problems, they should graph disciplinary incidents according to the school calendar in order to identify peak behavioral problem periods. (JG)

This paper presents guidelines for improving instructional text under three main headings: prose and grammatical features; tables and graphs; and typographical design. The paper has been printed in such a way as to illustrate the points made. (Author)

Describes an activity in which students analyze data from the Olympics. Discusses assessment of the activity and provides sample assessment form. (MKR)

Presents an approach that combines the discovery method with graphing skills and allows students to uncover scientific laws on their own. Attempts to make the discovery method more quantitative while still teaching students how to think scientifically. (JRH)

Presents a classification of factorable cubics and shows how the associated factor graphs determine domains of disconnected branches and furnish a skeletal framework for the number and shape of the branches. Illustrates three dimensional visualization and examines level curves and spikes of surfaces. (KHR)

Describes how one kindergarten classroom made pictographs and paper graphs of the students' acting preferences for a production of "The Wizard of Oz." Focuses on how the activity led to varied mathematics and literacy connections. Identifies implications from the Oz experience, including relating graphs to classroom contexts, using…

Uses graphs to involve students in inquiry-based population investigations on the Wisconsin gray wolf. Requires students to predict future changes in the wolf population, carrying capacity, and deer population. (YDS)

Emphasizes the commonalities among classes of polynomial functions. Provides exploratory activities for students as well as a teacher's guide. (KHR)

Illustrates the contrasting thinking processes of two beginning calculus students' geometric and analytic schemes for the derivative function. Suggests that teachers can enhance students' understanding by continuing to demonstrate how different representations of the same mathematical concept provide additional information. (KHR)
