As technology use continues to rapidly increase, so too does consumer use of web-based resources. While important, accessibility is often overemphasized by users when consuming and evaluating web resources. This prioritization may have particularly negative consequences for the selection of supports or interventions in educational settings. This…

Item exposure control is, relative to adaptive testing, a nascent concept that has emerged only in the last two to three decades on an academic basis as a practical issue in high-stakes computerized adaptive tests. This study aims to implement a new strategy in item exposure control by incorporating the standard error of the ability estimate into…

Cumulatively, participation in optional science learning experiences in school, after school, at home, and in the community may have a large impact on student interest in and knowledge of science. Therefore, interventions can have large long-term effects if they change student choice preferences for such optional science learning experiences. To…

By focusing on "appropriateness" and "adequacy" of inference and action, unified validity may be misused in rejecting valid test outcomes. The notion of levels of validity is challenged, the necessity of assumption is argued, and experience is proposed as the basis of validity. "Consequential validity" is interpreted as an optional predictive…

The Regression Model, popular in selection bias research, is proposed for use in item bias detection, providing a common framework for both types of bias. An empirical test of this new method, now called the Regression Bias method, and a comparison with other commonly used item bias detection methods are presented. (Author/BS)

This report examines how selection fairness is influenced by the item characteristics of a selection instrument in terms of its distribution of item difficulties, level of item discrimination, and degree of item bias. Computer simulation was used in the administration of conventional ability tests to a hypothetical target population consisting of…
