Discusses ways to use bar charts and line graphs to present comparative information in a flexible manner. Includes activities designed to review how the different characteristics of charts and graphs relate to different document structures. (RS)

Argues that graphs and charts are cases of document structures introduced in previous columns: combined lists, intersecting lists, and nested lists. Explores pie charts and various aspects of bar charts as they relate to other document structures presented in this series. (RS)

A theoretical foundation is provided for a method of identifying those books in a library's stack that determine any given percentage of the current circulation. Basic components and requirements of the technique are described, and the theory is applied in an example that manipulates data from a university library. (Author/MBR)

This theme issue is an attempt to improve graphical production by evaluators. The graphs that are described are solutions to problems in communicating evaluation findings. Eleven chapters and a conclusion discuss common and recurring problems for graphs for discovery or presentation, and for evaluators or evaluation audiences. (SLD)

Reviews evaluation standards that are used to assess the quality of projected graphical displays, and discusses their use in evaluating graphs created with computer graphing programs. Design standards for projected graphs are explained, and examples of three types of graphs are shown. (four references) (LRW)

Offers graphical proof of the proposition that the dynamically efficient allocation of a depletable, nonrenewable resource allows higher net benefits to users in both time periods than any other allocation. States that in this proof the result is more general and does not require the numerical specification of other previous models. (JEH)

Boswell Center Psychotropic Medication Efficacy Graphs were developed to monitor the longitudinal effects of psychotropic medication on individuals with mental retardation, with less reliance on anecdotal recollections. Levels of maladaptive and prosocial behaviors, medication side-effects, and psychotropic medication were considered…

A proposal for teaching how to graph functions is presented on the basis of the teaching theory of didactical situations implemented by the French author Guy Brousseau. The proposal is aimed at students in 12th grade in high school (USA) or in a freshman calculus course. The TI-92 graphic calculator was used as a teaching aid. (Author/ASK)

Describes how to use certain action research methods to increase researchers' access to intergroup relations embedded in organizations. Discusses studies using these methods in two corporations--one on work group relations and the other on race relations among Black and White managers--and notes implications for intergroup relations theory.…

Negotiations proposals can be evaluated by assigning advantage points and plotting these values on a negotiations analysis graph. Provided to illustrate the procedure are a table containing all proposal items submitted by both bargaining teams showing advantage point evaluations; four figures, each with four graphs, are also included. (MLF)

Discusses three phases of instructional design (ID)--definition of instructional parameters, analysis and synthesis of instructional alternatives, and implementation of instructional plan--and presents a 15-step ID model. Included for each step are a descriptive name, boxed example, and rationale and (as applicable) current state of technology for…

Discusses how grocery shopping activities can help primary and intermediate grade students develop mathematics skills useful in real life. (BB)

The article discusses strategies for parents to help their children improve math skills. It examines graphing skills and looks at three types of graphs (line graph, bar graph, and pie chart). Various simple activities illustrate what all scientists and mathematicians do when conducting experiments or developing mathematical models. (SM)

Discusses how to examine and evaluate claims of improved academic performance in advertisements for computer-assisted instruction. Highlights include the proper use of comparison groups; types of statistical analyses; the Hawthorne effect; the interpretation of scores; interpreting graphic presentations; tests of significance; and cost…

Discussed are the use of spreadsheets for demonstrating and exploring with the whole class, basic and advanced spreadsheet operations, geometric progressions, and graphing. Teacher responses to these methods are described. (CW)
