Instead of relying on standardized test scores and interdistrict comparisons, school systems must develop a more powerful, timely, and local approach to accountability that is truly client-centered and focused on results. Accountability requires giving successful teachers the freedom and opportunity to take effective ideas beyond their own…

One important and promising application of item response theory (IRT) is computerized adaptive testing (CAT). The implementation of a nominal response model-based CAT (NRCAT) was studied. Item pool characteristics for the NRCAT as well as the comparative performance of the NRCAT and a CAT based on the three-parameter logistic (3PL) model were…

A two-stage testing strategy is one method of adapting the difficulty of a test to an individual's ability level in an effort to achieve more precise measurement. A routing test provides an initial estimate of ability level, and a second-stage measurement test then evaluates the examinee further. The measurement accuracy and efficiency of item…

This report summarizes the results of a study of the achievement of Illinois high school juniors in 1970 and 1981. The purposes were to provide a comparison of student performance over a period of time and to identify educational, social, and personal conditions that relate to performance on a test of Natural Science, Social Studies, English and…

Southern Regional Education Board (SREB) states were invited in June 1984 to participate in a project with the National Assessment of Educational Progress (NAEP) to assess the reading achievement of eleventh grade students. Florida, Tennessee and Virginia accepted and worked with SREB and NAEP staff to develop and administer the testing program.…

The exact and closed-interval area measures for detecting differential item functioning are compared for actual data from 1,000 African-American and 1,000 white college students taking a vocabulary test with items intentionally constructed to favor 1 set of examinees. No real differences in detection of biased items were found. (SLD)

This article addresses the lack of outcome-based research on the integration of technology into pedagogy at the undergraduate college level. It describes a study performed at a Midwestern university, testing the relative effectiveness of paper and electronic topographic maps for teaching map-reading skills, and considers the relationship between…

A model-testing approach for evaluating the stability of item response theory item parameter estimates (IPEs) in a pretest-posttest design is illustrated. Nineteen items from the Head Start Measures Battery were used. A moderately high degree of stability in the IPEs for 5,510 children assessed on 2 occasions was found. (TJH)

The analytically derived asymptotic standard errors (SEs) of maximum likelihood (ML) item estimates can be approximated by a mathematical function without examinees' responses to test items, and the empirically determined SEs of marginal maximum likelihood estimation (MMLE)/Bayesian item estimates can be obtained when the same set of items is…

The Model-Assisted Reasoning in Science (MARS) project seeks to promote model-centered instruction as a means of improving middle-school science education. As part of the evaluation of the sixth-grade curriculum, performance of MARS and non-MARS students was compared on a curriculum-neutral task. Fourteen students participated in structured…

Recent studies show that national control of K-12 curriculum yields important payoffs in terms of greater curricular coherence and, as a result, higher test performance on international tests such as those used in the Third International Mathematics and Science Study. This paper examines the connection between national control of curriculum and…

This study used multiple methods to assess basic community needs and attributes of community atmosphere (cohesion, religious involvement, and recreational activities) in two psychometric studies. Part 1 revised self-report community assessment measures, developed multi-item scales for each construct, and tested reliabilities and factor structures…

Some results are presented relating to the dimensionality of the 1990 National Assessment of Educational Progress (NAEP) mathematics item-response data. Based on theoretical considerations, practical limitations, and previous research, two procedures were selected for study: full information factor analysis as implemented in the TESTFACT computer…

Several multiple-choice item formats are examined in the current climate of test reform. The reform movement is discussed as it affects use of the following formats: (1) complex multiple-choice; (2) alternate choice; (3) true-false; (4) multiple true-false; and (5) the context dependent item set. (SLD)

The standardization approach to comprehensive differential item functioning is described and contrasted with the log-linear approach to differential distractor functioning and the item-response-theory-based approach to differential alternative functioning. Data from an edition of the Scholastic Aptitude Test illustrate application of the approach…
