Analyzes computer terminal memory performance in terms of overflow probability and average queueing delay, and presents new method to derive a closed expression for data arrivals with Erlangly distributed interarrival times and an approach to derive steady state probability expressions of the terminal memory content process. Twenty references are…

Considers classifications produced by application of single linkage, complete linkage, group average, and word clustering methods to Keen and Cranfield document test collections, and studies structure of hierarchies produced, extent to which methods distort input similarity matrices during classification generation, and retrieval effectiveness…

Three hundred and twenty-four middle school students considered a group of three graphs in a newspaper article about boating deaths. The graphs contained discrepancies and the students were asked to "comment on unusual features." This form of questioning produced a distribution of responses surprising to the authors and perhaps…

This article is the result of an investigation of students' conceptualizations of calculus graphing techniques after they had completed at least two semesters of calculus. The work and responses of 27 students to a series of questions that solicit information about the graphical implications of the first derivative, second derivative, continuity,…

Acknowledging the need for additional practical resources for integrating technology into physical education assessment, this paper provides strategies and step-by-step instructions for incorporating Microsoft Excel into physical educators' assessment tools. The first section briefly reviews the literature on assessment in physical education. The…

The purpose of the study was to determine the effect of behavior contracting on grades attained by disadvantaged junior high school students. (Author)

Describes three classroom games for elementary school mathematics. Two are geoboard activities using a coordinate system; the third combines a knowledge of number facts with a game of tag. (RS)

Describes study of chemists in the Chemistry Division, Organic Research Laboratory, Eastman Kodak Company, as end-user searchers on the DIALOG system searching primarily the "Chemical Abstracts" database. Training, level of use, online browsing, types of searches, satisfaction, costs, and value of end-user searching are highlighted.…

The log C-pH diagram is a useful means of displaying quantitatively the many variables (including temperature) that determine acid-base equilibria in biological systems. Presents the diagram as extended to open/closed biological systems and derives a new water-ion balance method for determining equilibrium pH. (JN)

A model based on storage and retrieval costs that determines efficient allocation of materials to different storage regimes in academic libraries is developed. An economically rational basis for determining role of several alternative storage methods which distinguish among materials by expected level of use is offered. Nineteen references are…

A framework is presented for integrating use of a microcomputer into a statistics unit. Descriptions of some programs suitable for the Apple microcomputer and ideas for lessons are included. (MNS)

Examples of the use of hieroglyphics (glyphs) in science and medicine are presented. Suggests having academically talented science students use glyphs to make their own pictorial representations of their own data. (JN)

How graph paper has been used to illustrate the algorithm for division of fractions is presented. The combined use of graph paper and an overhead projector can make the presentation even more convincing. A review of whole number division is recommended prior to the lesson. (MP)

Presents a dynamic model of user behavior when scanning an information storage and retrieval system output list, compares rules for determining the user's optimum stopping point, presents an algorithm for implementing the Bayesian model, and discusses implications for retrieval system design. Provided are 13 figures and 15 references. (Author/RBF)

Two teaching ideas are shared. The first deals with a game called "Mathardy," which is similar to the old television show "Jeopardy," and which can be adapted to nearly any age and subject matter. The second idea deals with probability graphs of data from a basketball team. (MP)
