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)

Reviews an interactive statistical analysis package (designed to run on 8- and 16-bit machines that utilize CP/M 80 and MS-DOS operating systems), considering its features and uses, documentation, operation, and performance. The package consists of 40 general purpose statistical procedures derived from the classic textbook "Statistical…

Following a brief history of Logo, BASIC, and Pilot programing languages, common educational programing tasks (input from keyboard, evaluation of keyboard input, and computation) are presented in each language to illustrate how each can be used to perform the same tasks and to demonstrate each language's strengths and weaknesses. (MBR)

Describes experiences over several semesters with microcomputers in a mechanical engineering applied thermodynamics course. Includes course objectives, computer assignment structure, typical assignments, prewritten versus student-written software, and other topic areas. (JN)

Discusses what can be learned from and what should be expected from artificial intelligence research. Focuses on: (1) expert systems; (2) natural language processing; and (3) image processing. (JN)
