Describes the design and operation of four software packages, or macros, written in the programing language of Microsoft's EXCEL for use on the Macintosh computer for data manipulation and presentation used in educational research. Reordering tabulated data, reversing the scoring of tabulated data, and creating tables and graphs are explained.…

Demonstrates the application of multiple regression and double exponential elimination to patronage and circulation data collected at the School of Education at the University of Mississippi to examine the performance of its branch library. (six references) (MES)

Given is a proof on the classification of surfaces that involves some simple graph theory. It could serve as an introduction to some methods of modern differential topology. (MNS)

Spatial language in English and American Sign Language (ASL) was compared by asking 10 native signers and 10 English speakers to solve a set of spatial puzzles. The study highlights the ramifications of a linguistic system in which space itself is used to convey spatial information compared to one that conveys the same information via an auditory…

Suggests ways to translate ideas in the book, "The Story of Z," into data analysis activities in kindergarten and second-grade classrooms. (MKR)

Presents an alternate approach to teaching quadratics by fully integrating the study of quadratic equations and quadratic functions using graphs. Includes reproducible student worksheets. (MKR)

Presents a teacher's guide and reproducible student worksheets to develop the procedure for finding the inverse of a function. (MKR)

Describes a one-week lesson in which gummy-bears candy was used to illustrate sampling procedures and to generate discussion and questions. Reports data results and students' reactions to problems of representation after holding an election. (MKR)

Illustrates how to use computer simulation models in statistics to study the quality of an estimation procedure and concurrently the subtle concepts of randomness and convergence. Special emphasis is given to the use of graphical representations. (MKR)

Analysis of a sample of 100 pupil scripts from a British Assessment of Performance Unit survey suggests that ability to read and interpret graphical data should not be seen as an independent process skill. Instead, hidden cognitive demands of assessment items require integrated understanding based on a sophisticated procedural model. (SK)

Discusses the geometric interpretation of the roots of a quadratic equation. (MKR)

Introduces a strategy for writing equations of graphs to help students and teachers build strong conceptual connections between the symbolic representations of algebra and the spatial representations of geometry. (Author/MKR)

Provides a graphical framework for presenting interactions among current account flows, capital account flows, and exchange rates. Suggests that the two type of flows must be considered separately in discussions of foreign exchange equilibrium and balance of payments flows. Supplies sample graphs and instructions for applying the framework to real…

Discusses the types and functions of graphic displays found in textbooks, whether they facilitate learning, how well students read graphic displays, and what classroom teachers can do to help students read and interpret graphic displays. (SR)

Describes graphical techniques to help explain the multiple creation of deposits that accompany lending in a fractional reserve banking system. Presents a model that emphasizes the banking system, the interaction of total permitted, required, and excess reserves and deposits. Argues that the approach simplifies information to examining a slope…
