This comprehensive "Handbook" focuses on the most used polytomous item response theory (IRT) models. These models help us understand the interaction between examinees and test questions where the questions have various response categories. The book reviews all of the major models and includes discussions about how and where the models…

This discussion of library software packages includes guidelines for library automation with microcomputers; criteria to aid in software selection; comparison of some features of available acquisitions, circulation and overdues software; references for software reviews; additional information on microsoftware; and a directory of producers and…

Four English-as-a-Second-Language (ESL) dictionaries available in electronic form are compared and evaluated, focusing on content and organization, utility for students unused to the computer, inclusion of supplementary language corpora and other reference materials, multimedia capacities, and search options. (MSE)

Three methods employed to price and sell computer equipment are discussed: computer pricing, hardware pricing, system pricing (system includes complete computer and support hardware system and relatively complete software package). Advantages of system pricing are detailed, the author's system is described, and 10 systems currently available are…

Presented is a chart which compares the nature of the BASIC programing languages found with the following systems: Atari, Apple Integer, Applesoft, Exidy, TRS 80 Level I, TRS 80 Level II, TRS 80 DOS, and PET. (MP)

Comparison of three microcomputer statistical packages, SPSS, SAS, and BMDP, focuses on ease of use, ease of learning, documentation, accuracy, similarity to the mainframe version, and speed. The results of eight statistical multivariate analyses used to evaluate their performance are given. (LRW)

Applications are now available that allow teachers to create presentations and programs tailored to the exact needs of their students. This paper examines tools that may be used for presentations. Programming environments that may be used to develop computer aided instructional programs are also compared and contrasted. The availability of…

Because a microcomputer system can be an expensive acquisition, the purchase decision needs to be made carefully. Steps to purchasing a microcomputer include: evaluating the data and word processing needs of the office, determining needs being met with existing capabilities, and making a cost-benefit comparison among systems. (MLW)

A practical review of seven software directories is performed by comparing indexes, entry composition, subject classifications, and coverage overlap. The bibliographic control of microcomputer software and 13 microcomputer software directories published since 1980 are highlighted. (EJS)

Recent improvements in the human factors elements incorporated in the design of personal computer interfaces are illustrated by detailed analyses of two microcomputers and their word processors (Osborne 1/WordStar and Apple's Macintosh/MacWrite). The vital steps in operation are described through analyses of the behavioral requirements involved in…

Alternatives to the normal detail bid specifications usually required for public institutions of higher education to purchase computer software are examined. It is suggested that the request for proposal method described offers the consumer a better understanding of individual software vendors' products. (Author/SF)

Compares OCLC, WLN, and RLIN in terms of the composition of the databases, indexes and searching, special uses for public services, costs, and documentation. Selected bibliographies of general public service uses and interlibrary loan applications are provided. (CLB)

Describes and compares three versions of the ERIC database that are available on optical data disks: (1) DIALOG OnDisc ERIC; (2) OCLC Search CD450; and (3) SilverPlatter ERIC. The database contents, software and search commands, hardware requirements, notable features, and costs of each version are discussed. (CLB)

Discusses major features of microcomputers (word length, memory, size, disk size and capacity, central processing unit speed, peripherals, software) and provides descriptions of 19 models. Comparative analysis on basis of cost, software support, machine capacity, storage capacity, and types of peripherals is presented. A 173-item bibliography is…

This guide to ERRATA, a set of HyperCard-based tools for response analysis and error diagnosis in language testing, is intended as a user manual and general reference and designed to be used with the software (not included here). It has three parts. The first is a brief survey of computational techniques available for dealing with student test…
