Bay, Luz; Loomis, Susan Cooper; Wang, Tianyou – 1995
This study examines the effects on the National Assessment of Educational Progress (NAEP) achievement levels of using item response theory (IRT) models that have nominal missing-response parameters. It compares cutpoints based on item parameters that were fitted using two different models. The first set of cutpoints were based on parameters for…

O'Neill, Thomas R.; Lunz, Mary E. – 1996
To generalize test results beyond the particular test administration, an examinee's ability estimate must be independent of the particular items attempted, and the item difficulty calibrations must be independent of the particular sample of people attempting the items. This stability is a key concept of the Rasch model, a latent trait model of…

Mandeville, Garrett K.; And Others – 1975
A strategy for comparing two sets of results (one based upon early childhood recollections (ECR) and another upon video taped (VT) group behavior) from the Perceptual Characteristics Rating Scale was developed. The null distribution of the mean deviation was estimated by randomly matching an ECR response vector with a VT response vector. To…

Moyer, Robert Eugene – 1974
This study was designed to test the hypothesis that use of a probability unit in ninth-grade general mathematics classes would yield student improvement in computational skill, arithmetic reasoning, and attitude toward mathematics. A 47-page unit on probability (developed for this study) covered basic terminology, probability of events, favorable,…

Schrader, W.B.; Hilton, Thomas L. – 1975
Project TALENT, the Equality of Educational Opportunity Survey, and the Base-Year Survey of the National Longitudinal Study tested national probability samples of American high school seniors in 1960, 1965, and 1972. This study is concerned with the feasibility of using these data for studying trends in educational attainment. Three separate…

Millman, Jason – 1974
This chapter should not only acquaint the reader with the present state of the art on Criterion-Referenced (CR) measurement but also suggest possible directions for further inquiry. The goal of the first part of this chapter is to deal with the definitional dilemma of CR measurement by proceeding from the more traditional view of CR measurement to…
