How the computer can aid the teacher in discussing plane curves is shown. Use of the zoom enables the teacher to illustrate aspects of graphs that would be difficult and time-consuming to show in other ways. Many illustrative graphs are included, and four programs are listed. (MNS)

A method of using microcomputers to teach polar coordinates and graphing is described. Two computer programs plus illustrations are included. (MNS)

The problem of controlling the grizzly bear population at Yellowstone is described. The results are presented in graphical form and discussed. A computer program is included. (MNS)

The Hepatitis Knowledge Base (text of prototype information system) was used for modifying and testing "A Navigator of Natural Language Organized (Textual) Data" (ANNOD), a retrieval system which combines probabilistic, linguistic, and empirical means to rank individual paragraphs of full text for similarity to natural language queries…

This teacher's guide provides objectives, procedures, and list of materials needed for activities which center around the use of a scatter plot to examine relationships shown by bivariate data. The activities are suitable for grades 7 to 12. Four student worksheets are included. (JN)

Provides evidence of the devaluation of visuals in technical communication courses and also that pedagogical materials on visuals are at odds with current rhetorical theory and are increasingly anachronistic in the computer era. Discusses implications of the computers' impact for visual instruction and presents suggestions for future directions in…

Eleven experiments are presented, extending ideas for graphing functions presented in two previous articles. Computer program listings are included. (MNS)

This update of 1978 bibliometric study of online retrieval literature reveals that: literature has continued to grow, reaching peak annual output (504 papers) in 1981; conference literature has become centralized in four major proceedings; online retrieval papers have appeared in 479 journals; and 31 authors have contributed 10 or more papers.…

This article illustrates how Lotus 1-2-3 software can be used to create graphs using downloaded online searches as raw material, notes most commands applied, and outlines three required steps: downloading, importing the downloading file into the worksheet, and making graphs. An example in bibliometrics and sample graphs are included. (EJS)

Describes and compares three approaches to task analysis--behaviorally-based, concept-based, and cognitive process-based--and provides four tentative recommendations for determining which approach is appropriate in a particular situation. Five flowcharts and fourteen references are included. (MBR)

Discusses current use of psychological theory in software science and reviews recent developments in cognitive psychology relevant to programing (human information processing, expert-novice differences). Critique of Maurice Halstead's model of cognitive aspects of programing and a structured data flow perspective (control flow and data flow…

The various roles and uses of mathematics in developing global awareness in students are considered. Mathematics as a unifier of human experience and problem solving with a global emphasis are discussed with many illustrative examples. (MNS)

Techniques of exploratory data analysis (EDA) were used to decompose data tables portraying performance of ethnic groups on the Scholastic Aptitude Test. These analyses indicate the size and structure of differences in performance among groups studied, nature of changes across time, and interactions between group membership and time. (Author/DWH)

Demonstrates how a simple graph can be effectively used in teaching the concept, measurement, and use of humidity. Science activities for upper elementary, secondary, and higher education students are suggested and definitions of terms are presented. (Author/DB)
