Studies of group differences in intelligence often invite conclusions about groups in general from studies of group differences in selected populations. The same design is used in the study of group differences in other traits as well. Investigators observe samples from two groups (e.g. men and women) in some accessible population, but seek to…

For more than 20 years, the Ways of Coping Scale (WOCS) has been used extensively to measure coping. Yet beyond the original psychometric data, few studies have reexamined its properties utilizing the enormous body of research generated on the WOCS. Reliability has been assumed to be consistent as an attribute of the test. This study used…

This article presents an approach to systematic reviews that combines the Campbell Collaboration Crime and Justice standards and the realist notion of contexts-mechanisms-outcomes (CMO) configurations. Both approaches have their advantages and drawbacks, and the authors will make a case for combining both approaches to profit from their advantages…

Described here is a study on the efficacy of a digital media-rich curriculum based on the idea that children can learn best from "media synergy", that is, when children have opportunities to learn skills by engaging in repeated practice with them in many different formats and media (Neuman, 1995). The study is part of the "Ready to…

In this technical report, we provide reliability and validity evidence for the easyCBM[R] Reading measures for grade 2 (word and passage reading fluency and multiple choice reading comprehension). Evidence for reliability includes internal consistency and item invariance. Evidence for validity includes concurrent, predictive, and construct…

Background: The purpose of this study is to systematically retrieve, examine and discuss scientific studies focusing on motivational correlates that both contribute to, and can be assumed to be effects of, participation in sport, recreation, or health-related physical activities in persons with intellectual disability (ID). Methods: A systematic…

The purpose of this study was to examine whether the efficiency, precision, and validity of computerized adaptive testing (CAT) could be improved by assessing confidence differences in knowledge that examinees possessed. We proposed a novel polytomous CAT model called the confidence-weighting computerized adaptive testing (CWCAT), which combined a…

There is already a growing literature on assessment and an emergent scholarship that people in the scholarship of teaching and learning (SoTL) community need both to promote and to build on if assessment is to be a scholarly activity. Awareness alone, however, is unlikely to be enough. The poor practice highlighted in this article is not simply…

Student evaluations should "be ethical, fair, useful, feasible, and accurate" [JCSEE (2003). "The student evaluation standards." Arlen Gullickson, Chair. Thousand Oaks, CA: Corwin]. This study focuses on defining ethical behavior and examining educators' ethical judgments in relation to assessment. It describes the results from…

This article raises a number of questions about the current unified theory of test validity that has construct validity at its center. The authors suggest a different way of conceptualizing the problem of establishing validity by considering whether the focus of the investigation of a test is internal to the test itself or focuses on constructs…

Policymakers are fond of saying that we have enough research knowledge; however, one problem is that nobody is applying the knowledge we already have. This paper offers a discussion of the kinds of knowledge needed to improve students learning, what to do about this in the assessment and testing arena, and where assessment falls short. Types of…

Discussion of the evaluation of digital libraries suggests a conceptual framework for evaluation. Reviews evaluation efforts in research and practice; examines the derivation of criteria used in evaluation; states the essential requirements for evaluation; and discuses constructs, context, and criteria of digital libraries. (Contains 20…

"Ethical Challenges," in my experience, is invariably interesting, often instructive and sometimes amusing. Some of the most engaging stimulus scenarios raise thorny evaluation practice issues that ultimately lead to disparate points of view about the nature of the issue and how to handle it (Datta, 2002; Smith, 2002). Despite my poor performance…

Although the Angoff procedure is among the most widely used standard setting procedures for tests comprising multiple-choice items, research has shown that subject matter experts have considerable difficulty accurately making the required judgments in the absence of examinee performance data. Some authors have viewed the need to provide…

"Let's Begin with the Letter People"[R] is an early education curriculum that uses 26 thematic units to develop children's language and early literacy skills. A major focus is phonological awareness, including rhyming, word play, alliteration, and segmentation. Children are encouraged to learn as individuals, in small groups, and in a…
