The nation is challenged with improving the mathematics achievement of its students. No Child Left Behind holds schools, districts, and states accountable for improving student achievement. Because high stakes tests are given at the end of the school year, schools are presented with the challenging task of developing or purchasing reliable…

A literary debate has been ongoing from the early 1900s regarding not only the place of grammar instruction in the classroom but even of the veracity of a grammatical standard, such as Standard American English, by which grammar skills may be measured. Very little empirical research has been attempted to compare the effectiveness of teaching…

Students' attitudes toward mathematics and its learning have been subject to numerous studies in the past six decades. These studies treat such attitudes as both desirable learning outcomes and correlates of mathematics achievement. Many Likert-type attitude scales have been devised to measure significant constructs underlying mathematics-related…

Where as video cameras are a reliable and established technology for the measurement of kinematic parameters, accelerometers are increasingly being employed for this type of measurement due to their ease of use, performance, and comparatively low cost. However, the majority of accelerometer-based studies involve a single channel due to the…

The Multicultural Teaching Competencies Inventory (MTCI) contains items based on the tri-parte model of cultural competencies established by Sue and associates (Sue et al., 1992, 1982, 2003) that identify multicultural Awareness, Knowledge, and Skill as central characteristics of a culturally sensitive professional. The development and validation…

Although a few studies report sizable score gains for examinees who repeat performance-based assessments, research has not yet addressed the reliability and validity of inferences based on ratings of repeat examinees on such tests. This study analyzed scores for 8,457 single-take examinees and 4,030 repeat examinees who completed a 6-hour clinical…

Students experiencing test anxiety encounter extreme levels of stress, nervousness, and apprehension during testing that drastically hinders their ability to perform well and negatively affects their social-emotional and behavioral development, and feelings about themselves and school. A collaborative and multidimensional approach that includes…

Two Bayesian observer models were recently proposed to account for data from the Eriksen flanker task, in which flanking items interfere with processing of a central target. One model assumes that interference stems from a perceptual bias to process nearby items as if they are compatible, and the other assumes that the interference is due to…

All available studies on the Wartegg Zeichen Test (WZT; Wartegg, 1939) were collected and evaluated through a literature overview and a meta-analysis. The literature overview shows that the history of the WZT reflects the geographical and language-based processes of marginalization where relatively isolated traditions have lived and vanished in…

Interest in heart rate variability (HRV) metrics as markers of physiological and psychological health continues to grow beyond those with psychophysiological expertise, increasing the importance of developing suitable tools for researchers new to the field. Allen, Chambers, and Towers (2007) developed QRSTool and CMetX software as simple,…

Paul E. Newton argues in favor of a conception of validity, viz, "the consensus definition of validity," according to which the extension of the predicate "is valid" is a subset of "assessment-based decision-making procedure[s], which [are] underwritten by an argument that the assessment procedure can be used to measure the attribute entailed by…

As Paul Newton so ably demonstrates, the concept of validity is both important and problematic. Over the last several decades, a consensus definition of validity has emerged; the current edition of "Standards for Educational and Psychological Testing" notes, "Validity refers to the degree to which evidence and theory support the interpretations of…

In this article, nine mathematicians were interviewed about their why and how they presented proofs in their advanced mathematics courses. Key findings include that: (1) the participants in this study presented proofs not to convince students that theorems were true but for reasons such as conveying understanding and illustrating methods, (2)…

In this article, the authors examine the interconnections among education researchers' misconceptions about the quality of the education research literature. Specifically, the authors catalog the sequence of events that, when taken together with a series of contradictory graphs presented by influential scholars in prominent settings, may have…

The present article responds briefly to the comments, in this issue of "Educational Researcher," of Petrosino and of Robinson to the "Propagation of Misinformation About Frequencies of RFTs/RCTs in Education: A Cautionary Tale." The authors emphasize that the context of how the quality of education research is perceived both within and outside the…
