Standard procedures for estimating item parameters in Item Response Theory models make no use of auxiliary information about test items, such as their format or content, or the skills they require for solution. This paper describes a framework for exploiting this information, thereby enhancing the precision and stability of item parameter…

During the academic year of 1978-1979, a system for the early identification of students who were likely to have difficulty with the core curriculum in language and/or mathematics was introduced into the London, Canada, system at the kindergarten and grade 1 levels. In the two subsequent years the early identification system was extended to grades…

The "Test Development Notebook" is a resource designed for the preparation of tests of literal comprehension for students in grades 1 through 12. This volume contains 100 multiple-choice cloze exercises taken from consumer magazines, catalogs, instructions, advertisements, and contracts; and the accompanying answer key. Each exercise…

Statistical methods employed to test individual differences in dual-task performance and the existence of a general time-sharing ability are reviewed and critiqued. Specifically, both the types of data being collected and the types of data analysis procedures have been inadequate to the critical evaluation of a hypothetical…

Summary information and recommendations of the Nursing Delineation Study of the Kentucky Nursing Education Project are presented. Nursing tasks were identified, defined, and ranked as part of a systematic analysis of the nursing profession for the purposes of statewide planning. A 17-member task force represented the major domains of nursing…

The analysis of fit of data to a measurement model for graded responses is described. The model is an extension of Rasch's dichotomous model to formats which provide more than two levels of response to items. The model contains one parameter for each person and one parameter for each "step" in an item. A dichotomously-scored item…

The TESTFACT computer program and full-information factor analysis of test items were used in a computer simulation conducted to correct for the guessing effect. Full-information factor analysis also corrects for omitted items. The present version of TESTFACT handles up to five factors and 150 items. A preliminary smoothing of the tetrachoric…

Open testing and test disclosure legislation has fostered a renewed interest in the problems and issues associated with test equating. This paper focuses on a specific application of test equating, that of professional and occupational testing for certification and licensure. Test equating is the process of making test scores from different forms…

The development of distance and distributed learning environments on college campuses has created a need to reconsider traditional approaches to teaching and learning by integrating research and theories in human learning, pedagogy, and instructional technology. Creating effective and efficient multimedia for Web-based instruction requires a…

Empirical evidence is presented related to the effects of using a stratified sampling of items in multiple matrix sampling on the accuracy of estimates of the population mean. Data were obtained from a sample of 600 high school students for a 36-item mathematics test and a 40-item vocabulary test, both subtests of the Iowa Tests of Educational…

A review of the literature on the influence of testing on learning and retention reveals the need for more comprehensive research findings in this regard. This study was designed to investigate further the direct effects of tests in contrast with no tests on learning and retention in ongoing college-level classes with both the instructor and the…

Testing the assumption that textbooks were getting harder while students' abilities have been declining over the years, a study was conducted to determine the readability levels of six college reading textbooks across three editions to see if they were equal or the same in readability. The study also sought to determine whether these texts were…

Many factors influence the comprehension of a linguistic act by a listener or reader. Some, such as maturity, background, and interests of the decoder are nonlinguistic; others, such as the vocabulary and complexity of the morphological and syntactical structures are linguistic in nature. A review of the literature reveals that while studies have…

Growth of administrative components in 43 K-12 public school districts in the Saint Louis metropolitan area is reported for 1968-76. Increases in absolute numbers and ratios of administrators to teachers occurred in school districts with increasing as well as declining enrollments. Statistical analysis of public records and interviews with…

This paper analyses new methods of teaching skiing in terms of a computational paradigm for learning called increasingly complex microworlds (ICM). Examining the factors that underlie the dramatic enhancement of the learning of skiing led to the focus on the processes of simplification, debugging, and coaching. These three processes are studied in…
