Dr. Tracey Burns is a Senior Analyst in the OECD's Centre for Educational Research and Innovation. She heads a portfolio of projects including Innovative Teaching for Effective Learning, 21st Century Children and Trends Shaping Education. Until recently she was also responsible for the OECD work on Governing Complex Education systems. Previous to…

The growing presence of computer-based testing has brought with it the capability to routinely capture the time that test takers spend on individual test items. This, in turn, has led to an increased interest in potential applications of response time in measuring intellectual ability and achievement. Goldhammer (this issue) provides a very useful…

Whenever a major intelligence or achievement test is revised, there is always renewed interest in the underlying structure of the test as well as a renewed interest in the scoring, administration, and interpretation changes. In this interview, Amy Gabel discusses the most recent revision of the "Wechsler Intelligence Scale for Children-Fifth…

Presents recommendations for improved testing practices in science based on an examination of contemporary assessment literature and interviews with educators. The recommendations address test format, teacher involvement in all steps of the testing process, and use of sampling strategies and computer technology. (MBR)

The symposium, "Taming the Rasch Tiger: Using Item Response Theory in Practical Educational Measurement," was organized to deemphasize the technical complexities of item response theory (IRT) and to show the audience how IRT can be used in practical educational measurement. Four papers from the symposium are summarized and comments are…

Item banking offers psychometric efficiency and user flexibility when compared with standardized testing. This article discusses the theories, procedures, and potential of item banks for improving educational measurement. (BS)

Potential benefits of using item response theory in test construction are evaluated, based on the experience and evidence accumulated during 9 years of using a three-parameter model in the construction of major achievement batteries. Specific benefits covered include obtaining sample-free item calibrations and item-free person measurement,…

This paper has shown the advantages of tailored testing over traditional methods, the need for latent trait theory in the application of tailored testing, and some of the results available to show the quality of estimates obtained by tailored testing procedures. Since the tailored testing procedures overcome many of the problems with traditional…

The author argues that scoring, reporting, and deriving final grades can be considerably assisted by using a computer. He also contends that the savings in time and the computer database formed will allow instructors to determine test quality and reflect on the quality of instruction. (BW)

The current technology of computerized testing is discussed, and a few comments are made on how such technology might be used for assessing school-related skills as part of the National Assessment of Educational progress (NAEP). The critical feature of computerized assessment procedures is that the test items are presented in interactive fashion,…

The potential use of criterion referenced tests (CRT) and norm referenced tests (NRT) in the same testing program is discussed. The advantages and disadvantages of each are listed, and the best solution, a merging, is proposed. To merge CRTs and NRTs into an overall testing program, meaningful and useful to all levels, consideration must be given…

The potential value of developing item banks that would both guarantee the quality of teacher-made examinations and allow for national comparison of student achievement is described. Use of Rasch model methods, rather than classical item analysis techniques, to calibrate the items for these banks is illustrated. (BS)

For many years personalization of achievement testing has been impossible in all but the simplest forms. Recently, item response theory (IRT), or latent trait theory, has emerged as a valuable tool which brings far greater flexibility to the process than had previously been possible. The single parameter Rasch Model, a mathematical model developed…

Provides guidelines for teachers writing machine-scored examinations. Explains the use of item analysis (discrimination index) to single test items that should be improved or eliminated. Discusses validity and reliability of classroom achievement tests in contrast to norm-referenced examinations. (JHZ)

Possible future practices in testing are discussed, with a critique of current educational measurement. As standardized achievement tests are used for wide-ranging purposes, there will be increasing reliance on item response theory and national item banks. A national system of monitoring development and use of tests will probably emerge. (SLD)
