Models of modern test theory imply statistical independence among responses, generally referred to as "local independence." One violation of local independence occurs when the response to one item governs the response to a subsequent item. Expanding on a formulation of this kind of violation as a process in the dichotomous Rasch model,…

In 1997, based on the amendments to Individuals with Disabilities Education Act (IDEA), all states were faced with a statutory requirement to develop and implement alternate assessments for students with disabilities unable to participate in the statewide large-scale assessment. States were given the challenge of creating, implementing, and…

Uses a framework previously developed to relate outcomes based education and B. Bloom's "Taxonomy of Educational Objectives" to consider ways in which modern test theory can be used to connect aspects of assessment to the curriculum framework and to consider insights this connection might provide. (SLD)

Presents minimization and maximization models for parallel test construction under constraints. The minimization model constructs weakly and strongly parallel tests of minimum length, while the maximization model constructs weakly and strongly parallel tests with maximum test reliability. (Author/SLD)

Binomial models for domain-referenced testing are compared, emphasizing the assumptions underlying the beta-binomial model. Advantages and disadvantages are discussed. A proposed item sampling model is presented which takes the effect of guessing into account. (Author/CM)

Test theory encompasses models and methods for drawing inferences about what students know and can do, cast in a framework of ideas from measurement, education, and psychology. The emerging paradigm of cognitive psychology prompts new considerations about collecting and interpreting evidence, suggesting alternative models for the nature,…

On the basis of the characteristics of criterion-referenced tests, the contribution of German research to the development and application of criterion-referenced tests is discussed. (PN)

Description of an objective method for assigning weights to questions on examinations includes discussions of classical test theory, knowledge organization, and how task analysis can be used to identify knowledge elements required to solve specific problems, rank them, and assign objective weights to exam questions using a Pareto distribution (7…

Suggests that any model of washback must include insights from the theory of educational innovation to help explain why tests do not always have the desired or feared effect. Key concepts in educational innovation are reviewed, showing how these concepts are manifested in a case study in washback and outlining how they are being applied in recent…

The goal of test design is to devise an instrument that will provide a stable and accurate assessment of student ability in some area. One means of reaching this goal is through the use of latent trait models, which determine the relationship between the unobservable trait or ability and the observable test performance. Three common latent trait…

The renewed attention to assessments that attempt to capture complex aspects of educational attainments of students is explored. The definition and impetus for attention of the measurement community to higher order thinking skills are examined. Through a detailed description, a model assessment development process is presented. The process relies…

An empirical review of test items is described as an essential step in criterion-referenced test development. The concept of test items' instructional sensitivity is introduced, and research is briefly reviewed which describes four theoretical contexts in which instructional sensitivity indexes have been observed: criterion-referenced; classical…

Major changes in educational and psychological theories that have come about since the cognitive and affective taxonomies of educational objectives were published in 1956 and 1964 are traced. The changes emphasize the need to understand thinking in the context of students' beliefs and self-directed cognitions. (SLD)

A procedure is demonstrated for constructing tables showing, for each score on a commercial reading achievement test, the percentage of real-world materials that the testee is likely to comprehend with at least a criterion level of proficiency, the percentages of students in a local or national sample who can competently comprehend a given…
