Graphical perception is the visual decoding of the quantitative and qualitative information encoded on graphs. Some recent theoretical/experimental investigations of graphical perception are described, identifying certain elementary graphical-perception tasks that are performed in the visual decoding of quantitative information from graphs.…

This article briefly describes the topics "beta coefficient"--a measurement of the price volatility of a company's stock in relationship to the overall stock market--and "market share"--an average measurement for the overall stock market based on a specified group of stocks. It then selectively recommends a database (file) on…

Library user guides from seven large academic libraries were examined for readability using microcomputer software for analysis. Results indicated that most guides are written at or above a reading level of grade 12. Appendices summarize readability formulas and depict in a composite graph the levels of all of the guides examined. (16 references)…

Discusses the hardware and software necessary to generate charts and graphs to illustrate numeric data using a microcomputer. The manufacturer, price, operating system, memory requirements, and types of graphs they can produce are given for nine graphics software packages and seven inexpensive plotters. (MBR)

Suggestions for writing computer programs for instructional purposes are provided. Program listing for displaying a bar graph on a TRS-80 computer and listings for two subroutines (advancing frame and entering name on Apple computer) are included. (JN)

A sequence of exploratory activities is designed to help beginners use the BASIC language and make simple pictures by graphing pairs of numbers. (MNS)

This guide to the discovery, analysis, production, communication, and use of statistical information through graphic forms produced by a computer is designed to enable researchers to conduct their analyses and report research results more effectively. It is designed both for individuals with little knowledge about the use of statistical graphs or…

Use of Logo to teach statistical ideas is proposed for students in grades 5-10. Procedures and diagrams are suggested, with program listings for four models for graphs. (MNS)

Given is an example of the solution of maximum-minimum problems by replacing differentiation techniques with microcomputers and simple BASIC programs. (MNS)

Alternative educational applications of microcomputer technology in allied health are discussed, including word-processing software for creation and revision of syllabi, exams, and handouts; database management software for creation of large sets of bibliographic references, storage and retrieval of data on students; spreadsheet software; and…

Three activities with Knuth functions are discussed and illustrated, with sample computer programs listed. (MNS)

The development and use of an activity that uses the computer's unique capabilities to provide students with a relevant and highly motivating experience with the graphing of equations is outlined. The activity, called "Green Globs," illustrates the potential of developing new environments for learning on computers. (MP)

Describes the new concept of HYPERBASE and its relationship to classical hypermedia; a multimedia database retrieval system (SOPHIADOC) and its features in relation to the HYPERBASE concept; and an experimental use of SOPHIADOC to organize and scroll selected images on the "First Emperor of China" videodisk. Fifteen project publications…

Low cost microcomputers with high resolution graphics provide students and educators with fast and accurate visual representations of mathematics relations and extend the benefits of discovery learning into the high school and college mathematics classroom. A recent challenge has been to use the computer in motivating students and teaching…

One way in which a computer simulation can convince students of the validity of formulas for the density and distributive functions of the sum of two variables is described. Four computer program listings are included. (MNS)
