This article provides an overview of the instructional design principles underlying the effective use of graphic communication devices in geography texts. The topics covered include labelling, figure-ground relationships, signs and symbols, legends and keys, and graphic integrity. Includes graphic examples. (JDH)

Discusses reliability and validity of continual response measurement (CRM), a computer-based measurement technique, and its use in social science research. Highlights include the importance of criterion-referencing the data, guidelines for designing studies using CRM, examples typifying their deductive and inductive functions, and a discussion of…

Describes a series of activities without conclusions to introduce scientific reasoning in a ninth grade physical science course. Uses popcorn popping to get students to think about the concepts of graphing, histograms, frequency, probability, and scientific methodology. (CW)

Eighth grade physical science students studied graphing with a microcomputer as the lab partner in a microcomputer based laboratory. Graph templates were used to solve problems based on previous learning. It was concluded that the Computer as Lab Partner curriculum was effective in teaching graphing concepts. (GDC)

Programs (using Logo) developed by children to produce multiples, the Fibonacci series, and square numbers are presented, with graphical representations of functions introduced. Another investigation involves drawing a circle using turtle graphics. (MNS)

Computer algebra systems (such as MACSYMA and muMath) can carry out many of the operations of calculus, linear algebra, and differential equations. Use of them with sketching graphs of rational functions and with other topics is discussed. (MNS)

Studies the effects of varying levels of interactivity on the learning rate of 98 high school students using four increasingly interactive versions of computer-based interactive video instruction. Students are grouped by ability levels and results are compared for recall rate, instructional time, and acquisition rate. Twenty-two references are…

Ways of solving a problem on the connection between heat loss and the ratio of surface area to volume are described. Tables and graphs are included. (MNS)

MINDS (Multiple Intelligent Node Document Servers) is a distributed system of knowledge-based query engines for efficiently retrieving multimedia documents in an office environment of distributed workstations. By learning document distribution patterns and user interests and preferences during system usage, it customizes document retrievals for…

Examines relationship between journal productivity (number of references to particular journal) and journal obsolescence (median age of references to particular journal) for database of references dealing with desalination. Citation age by Bradford zones, continuous measurement of productivity and citation age, and underlying structure of observed…

Results of a survey of educational technology graduate students at San Diego State University (SDSU) include student characteristics, reasons for attending SDSU, and occupational aspirations and job titles. Also presented are questions and issues relating to marketing efforts, curriculum improvements, and trend anticipation that were raised by the…

Reports algorithm for calculation of term discrimination values that is sufficiently fast in operation to permit use of exact values. Evidence is presented to show that relationship between term discrimination and term frequency is crucially dependent upon type of inter-document similarity measure used for calculation of discrimination values. (13…

Results of survey evaluating physical condition of 36,500 volumes and nature of collections in Yale University Library system reveal that 37.1 percent of books sampled overall had brittle paper and 82.6 percent had acidic paper. Sampling methodology, survey instructions, abbreviations for publishing countries, and methods of statistical analysis…
