The advantages and disadvantages of new software for market segmentation analysis are discussed, and the application of this new, chi-square based procedure (CHAID), is illustrated. A comparison is presented of an earlier, binary segmentation technique (THAID) and a multiple discriminant analysis. It is suggested that CHAID is superior to earlier…

Flowcharting of algorithmic procedures can be a useful tool for teachers of remedial arithmetic. (SD)

A system study of the textbook ordering department is presented including systems flow chart, chart of activities, and description of operations and procedures for utilizing the computer system. Changes based on the study are noted. (JT)

Upper-level secondary students investigated square and triangular numbers and Pythagorean triples using computers. (SD)

Presents a description of the computer simulation model developed by the National Educational Finance Project for use by States in planning and evaluating alternative approaches for State support programs. Provides a general introduction to the model, a program operation overview, a sample run, and some conclusions. (Author/WM)

During the academic year 1983-84, Drexel University instituted a new policy requiring all incoming students to have access to a microcomputer. The computer chosen to fulfill this requirement was the Macintosh from Apple Computer, Inc. Because Drexel University received one of the first large shipments of this new product, the degree to which these…

This report discusses an iterative methodology for logical database design (LDD). The methodology includes four phases: local information-flow modeling, global information-flow modeling, conceptual schema design, and external schema modeling. These phases are intended to make maximum use of available information and user expertise, including the…

This paper contains the technical specifications, schematic diagrams, and program printout for a computer software package for the development and administration of diagnostic tests. The second version of the Diagnostic Testing Package DX consists of a PASCAL-based set of modules located in two main programs: (1) EDITTEST creates, modifies, and…

This report describes a collection of procedures, with illustrative examples, for selecting and portraying microcomputer courseware in a manner that enables others to make their own judgments of courseware quality. Following a discussion of perspective and a report outline, section 3 deals with assumptions underlying the search to identify…

Flowcharting, a skill used to program computers, can be used to teach reading skills. Like programing, flowcharting requires knowledge of a particular content area and an understanding of how to process the information. Skills such as identifying the main idea and supporting details, sequencing ideas or statements, and distinguishing relevant from…

This loose-leaf manual was compiled during a cataloging and indexing project which covered government publications issued primarily by regional offices, field offices, federal-state organizations, quasi-official agencies, or non-governmental institutions producing federally funded reports. Processing of these publications utilizes the National…

Characteristics of liberal arts education and different approaches to educational modeling are examined. Attention is directed to: applications of graphic depictions; Venn-Euler diagrams to represent inclusion-exclusion phenomena as well as areas of commonality in learning processes and liberal education; the uses of flow charts for describing…

This investigation of the encoding features of graphs begins with a description of a cognitive framework which allows designers to factor into the process of designing displays how people interpret the information found and what display properties are responsible for this interpretation. The framework also provides a performance measure for use in…

The paper demonstrates the use of algorithmic thinking through an operational analysis of the "rural exodus" in Western Europe, focusing on several Swiss Alpine villages. (Author/KM)

Emphasis on broad-based institutional planning is largely a phenomenon of the seventies. One reason is that the value placed on it varied inversely with the availability of resources. Yet the state of the art of planning for change is not far advanced. There is evidence that those institutions doing this kind of planning tend to be private,…
