Because the cost of computer software is expensive and hardware costs are going down, it is important to choose software systems that are independent of hardware. (JOW)

A systematic assessment procedure designed to increase success at buying supportable software is presented. Examples used are from programs for the IBM PC, but most comments apply to other software and to software for minicomputers and mainframes. (MLW)

Describes a microcomputer-based string index format generated from concept networks using multiple search terms. Link weighting is highlighted as a method to decide which term appears first so the entry reflects the classification implied by the search specification. The computer software used for this system is briefly described. (Author/LRW)

Subroutines to calculate exact chi square and Fisher's exact probability tests are presented for 3 by 2 cross-classification tables. A nondirectional probability value for each test is computed recursively. (Author/GDC)

Lord's method for detecting subgroup bias at the item level uses a three-parameter item characteristic curve model. A chi square statistic is computed on the multivariate differences between the parameter estimates of item discrimination and difficulty. The LOGIST program and additional programs written in BASIC are used. (Author/GDC)

The viability of the FORTRAN computer language and its relationship to other languages (such as PASCAL) were discussed. A library of C language and assembly language FORTRAN-callable subroutines, developed for the use of behavioral science researchers, was introduced. (Author/GDC)

Discusses the potential of computerized school-based record systems to help monitor the 1990 and future health objectives for the nation, to provide a continuing health database on nearly 50 million Americans, and to improve current school health recordkeeping practices. (JOW)

Explains the use of computerized bookkeeping systems called spreadsheets to perform mathematical and accounting functions such as totaling expenditures, averaging test grades, and transferring funds. Advises about adapting spreadsheet programs and discusses several essential features, including linkage, macro functions, and sharing capabilities.…

Computer viruses are programs that propagate themselves from disk to disk and destroy programs or information files. Several universities have recently reported virus outbreaks. Some suggestions for avoiding the viruses are provided. (MLW)

Discusses the use of beginning, intermediate, and advanced databases for instructional purposes. A table listing seven databases with information on ease of use, smoothness of operation, data capacity, speed, source, and program features is included. (JN)

Reports the results of a comprehensive study to determine the needs and development opportunities for the use of microcomputers in foreign language instruction in elementary and secondary schools. Includes recommendations for software development, teacher training, curriculum development, and the role of the schools. (JDH)

This article evaluates three general types of computer-assisted approaches to multicriteria decision problems in which criteria are attributes as opposed to objectives. Several programs specifically designed for multiattribute problems, as well as spreadsheets and decision-free software, are discussed. (Author/BS)

This paper presents a BASIC microcomputer program that constructs the Tukey (1977) stem and leaf graph. Options within the LEAF program include a modified stem and leaf where the stem is split and a parallel stem and leaf graph where two separate sets of data are displayed from a common stem. (Author)

Using a computer gradebook can minimize time spent calculating grades. Nine software programs for grading are reviewed. (MNS)

This description of ways in which database management systems can be helpful in instructional media centers explains the basic terminology involved and how to plan, create, modify, maintain, and use databases. Examples provided include an equipment distributions form and the structure for a film/video rental database. (LRW)
