In this digital ITEMS module, Dr. Jue Wang and Dr. George Engelhard Jr. describe the Rasch measurement framework for the construction and evaluation of new measures and scales. From a theoretical perspective, they discuss the historical and philosophical perspectives on measurement with a focus on Rasch's concept of specific objectivity and…

Research on psychometric methods is heavily dependent on software. The quality, availability, and documentation of such software are critical to the advancement of the field. In 2000, an ad hoc committee of NCME recommended that NCME adopt policies that promote greater availability and better documentation of software. This article follows the ad…

While there is much enthusiasm about the potential of microcomputers in test development and item banking, testing specialists have no interest in actually purchasing a turnkey test construction system. Focusing development efforts on providing methods to assist test directors, rather than external systems which replace institutionalized…

The purpose of this paper is to describe some of the current changes in test development that are taking place because of the availability and capabilities of computers, especially microcomputers. Item banking and test assembly are discussed, and a comprehensive testing system is described. (BW)

MicroCAT version 3.0--an integrated test development, administration, and analysis system--is reviewed in this first article of a series on testing software. A framework for comparing testing software is presented. The strength of this package lies in the development, banking, and administration of items composed of text and graphics. (SLD)

Two easy-to-use microcomputer programs, the Student Problem Package and the Test Analysis Package, both by D. L. Harnisch et al. (1985), are described. These programs efficiently analyze test data for teachers. (SLD)

The constructive use of microcomputers in the development of tests requires thoughtful attention to the questions addressed in this paper: What is the purpose for testing? How can a microcomputer help? Which microcomputer system is best? What pitfalls should be avoided? (BW)

The history of microcomputer use in education is traced, from 1950 to the present, and implications for testing applications are reviewed. Future trends in statistical analysis packages, mass storage, improved graphics, and integration of components are discussed. (BW)

In providing an alternative view to the previous article by Ward (TM 508 880), the author notes problems associated with adaptive testing, diagnostic testing, testing embedded in instruction, and testing through simulations. (BW)

This article describes a number of problems every educational measurement specialist should be prepared to confront before using microcomputers to support test-related activities, including problems with hardware, with software, and with implementing a system. It concludes with a checklist for planning a microcomputer application. (BW)

How computers are used to analyze item data is reviewed, and the information that existing item-analysis programs provide is described. Summaries of studies comparing the performance of some of these packages reveal some of their current limitations. Emphasis is on the usefulness to educational practice of these packages. (SLD)

Some of the benefits available from using computers to administer the kinds of tests that are familiar in educational settings are reviewed. Four applications that represent current or near-term enhancements of assessment are discussed: computerized adaptive testing, diagnostic testing, test preparation, and administration of simulations of…
