This study used multiple regression analysis to relate computer user satisfaction to communication monitor (CM) variables. Results indicate the variables of user expectations, manufacturers, and vendors are most significant in affecting overall satisfaction, whereas number of systems represented and not using communication monitors have least…

An application of functions and their inverses is described--the coding and decoding of messages, or cryptographs. The helpfulness of computers is noted, with two programs listed. (MNS)

Cites six new ERIC documents for teaching economics in the elementary and secondary classroom. Topics include: teaching strategies; free and inexpensive materials; software; unions; and lifestyles. Also indicates how the documents can be ordered or searched for. (TRS)

Discusses artificial intelligence, robotics, natural language processing, and expert or knowledge-based systems research; examines two large expert systems, MYCIN and XCON; and reviews the resources required to build large expert systems and affordable smaller systems (intelligent job aids) for training. Expert system vendors and products are…

Presented are two problems that can be solved using a computer simulation by students who have completed Algebra II. The distance and bisector formulas and the various forms of the equations of a circle and straight line are the topics. Computer program listings are included. (MNS)

This description of the design of an online library acquisition system highlights the use of database management systems in developing information retrieval systems, and software requirements for the hierarchical menu-driven operation. A conceptual view of the database is included. (LRW)

Reports on the design and use of a computer system--SORT-AID--to assist bibliographic database searchers in the post-search, analysis phase of their work. Designed for National Aeronautics and Space Administration (NASA) installations, this system automatically determines the relevance of downloaded abstracts and provides facilities for editing…

Examines a number of language activities in educational software, noting that most focus on surface structure and conventions, thus closing off students' options rather than expanding them. Discusses how, by improvising with word processors, teachers can tailor activities to help students explore and reflect on their reading and writing…

Reports on the design and use of a computer system designed to assist online database searchers in determining the relevance of downloaded abstracts. The system, which runs on a personal computer, includes aids for individual review of abstracts and semiautomatic determination of relevance; prospects for fully automatic use are discussed. (CDD)

Described is the Alfa Project in Uruguay, designed to integrate computer education into secondary schools through teacher-training. Both teacher-users and teacher-authors were considered. Course objectives, curriculum content, and teaching guidelines are presented. (MNS)

Numerical inaccuracies, which occur in many ordinary computations, can create serious problems and render answers meaningless. Cancellation and accumulation errors are described, and suggestions for experimentation are discussed. (MNS)

A computer program that can be easily modified to offer individualized drill, practice, or remediation is presented. How the program operates is described, and how to modify it for numerical order, number sequences, number words, inequalities, basic operations, percents, decimals, fractions, and measurement is noted. (MNS)

Provides information gained from a survey of 129 university departments of journalism. Reports that most now use personal computers and video display terminals to teach editing and news writing. (FL)

Vignettes illustrate the effectiveness of a project providing computer-assisted instruction to three multiply-handicapped deaf high school students. Individual and group activities resulted in increased language skills, more positive attitudes, greater self-esteem and motivation, and improved peer interactions. Software programs are briefly…

The current status of Computer-Assisted Telephone Interviewing (CATI) is reviewed with special attention to microcomputer-based systems. The primary conclusion is that CATI systems can aid in the administration of telephone surveys in addition to reducing sources of survey error, but CATI systems are neither inexpensive nor easily implemented.…
