APL was invented specifically as a mathematical teaching tool, and is an excellent vehicle for teaching mathematical concepts using computers. This article illustrates the use of APL in teaching many different topics in mathematics, including logic, set theory, functions, statistics, linear algebra, and matrices. (MNS)

Some limitations of computing with calculators and computers are described, with particular reference to typical computations which might be performed by senior secondary school students. Types of errors, the laws of number, and intermediate round-offs are each illustrated, with conclusions and implications. (MNS)

The current use of computer technology in counseling psychology is explored and the potential negative impact of computer technology is discussed in terms of the misuse of computer applications, dependence on technology, and restriction of the counseling process. Factors contributing to inappropriate use of technology are also discussed along with…

The use of computerized decision support systems in higher education for making tactical institutional decisions is reviewed, with attention to the kind of administrative problems that lie somewhere between programmed to nonprogrammed decisions and require a combination of computer support and administrative judgment. (MSE)

Provides highlights of topics and issues discussed at a conference that addressed the impact that modern information processing technology is having on engineering disciplines. Includes a list comparing 1980's emphasis to 1990's emphasis in mathematics, basic sciences, engineering fundamentals, economics, communications, humanities and social…

Describes a microcomputer program (written for the Apple II+) which can serve as a lecture demonstration aid in explaining genetic transcription and translation. The program provides unemotional information on student errors, thus serving as a review drill to supplement the classroom. Student participation and instructor options are discussed. (DH)

Presents data model based on text data model (TDM), universal relation model, and nonfirst normal form (NFNF) relations, and discusses applicability to text processing and document retrieval systems. Highlights include database technology applied to information retrieval, NFNF and universal relation, and TDM integration with NFNF universal…

Discusses uses of microcomputers as: a tutor (drill and practice, course review, and others); a tool (drawing, statistical analyses, word processing, and others); and a tutee. Also addresses major problems and issues in science education, noting how microcomputers may help in resolving the problems. Problems and issues include teaching science in…

Provides results of a 10-item survey which includes data on years in education, salaries, willingness to leave education, attitude toward moving to industry, and computer-oriented areas. Indicates that nearly 70 percent of administrators (compared to overall average of 62 percent) are ready to leave education. (JN)

Discusses number and type of microcomputer software programs useful to libraries and types of hardware on which they run, as identified by Nolan Information Management Services. Highlights include general application programs, applications designed to support library technical processes, producers of library software, and choosing among options.…

Describes how microcomputers, together with an in-house developed expert system, are assisting Sweden's Linkoping University library staff, who possess beginning programing skills and computer expertise, in improving library performance. An example illustrating how the dimensional flowcharting improved the interlibrary loan operation is presented.…

Methods to make computer searching as simple and efficient as possible have led to the development of various data structures. Data structures specify the items involved in searching and what can be done to them. The nature and advantages of using "self-adjusting" data structures (self-adjusting binary search trees) are discussed. (JN)

The National Academy of Sciences suggests models for biomedical research which include a biology-wide information system with computerized database accessible from a multitude of dimensions. Links could help discover whether toxic chemicals have effects similar to hormones. Commonalities from molecules to ecosystems might restructure available…

The development of the Drexel Disk is described. The goal of this disk is to train novice users of a personal computer and to provide them with all the information they need to be able to use the machine and the facilities at Drexel. (MLW)

Through a discussion of research on institutions using computer-based planning models, this question is addressed: How does the institutional decision maker make decisions using state-of-the-art computing tools without neglecting nonquantitative realities? (MSE)
