The importance of higher education has never been clearer. Educational attainment--the number of years a person spends in school--strongly predicts adult earnings, as well as health and civic engagement. Yet relative to other developed nations, educational attainment in the United States is lagging, with young Americans who heretofore led the…

Value-added measures of teacher quality may be sensitive to the quantitative properties of the student tests upon which they are based. This paper focuses on the sensitivity of value- added to test-score-ceiling effects. Test-score ceilings are increasingly common in testing instruments across the country as education policy continues to emphasize…

Images, whether at the level of molecules, cells, organs, organisms, or environments, are at the core of many biological disciplines. Even with the contemporary emphasis on molecular analysis, biology has retained its traditional strong visual component. In courses that rely on the study of biological structure, the presentation of images for…

What are the problems that early childhood educators are trying to answer? In this article, the author presents his ten concerns for early childhood teacher education: (1) A concern about policymakers' pottery wheels; (2) A concern about "white shoe" education evangelists; (3) A concern that increasing control may cripple autonomy and…

Multisample measured variable path analysis is used to test whether causal/structural relations among measured variables differ across populations. Several invariance testing approaches are available for assessing cross-group equality of such relations, but the associated test statistics may vary considerably across methods. This study is a…

This article suggests a method for estimating a test-score equating relationship from small samples of test takers. The method does not require the estimated equating transformation to be linear. Instead, it constrains the estimated equating curve to pass through two pre-specified end points and a middle point determined from the data. In a…

Purpose: "Electromagnetic articulography (EMA)" uses a helmet to create alternating magnetic fields for tracking speech articulator movement. An important safety consideration is whether EMA magnetic fields interfere with the operation of speakers' pacemakers or implantable cardioverter-defibrillators (ICDs). In this investigation,…

This study demonstrated selective "rational" imitation in infants in two testing conditions: in the presence or absence of the model during the response phase. In the study, 14-month-olds were more likely to imitate a tool-use behavior when a prior failed attempt emphasized the logical reason and relevance of introducing this novel means, making…

The touchscreen testing method for rodents is a computer-automated behavioral testing method that allows computer graphic stimuli to be presented to rodents and the rodents to respond to the computer screen via a nose-poke directly to the stimulus. The advantages of this method are numerous; however, a systematic study of the parameters that…

Computer-based testing--is an effective teacher's tool, intended to optimize course goals and assessment techniques in a comparatively short time. However, this is accomplished only if we deal with high-quality tests. It is strange, but despite the 100-year history of Testing Theory (see, Anastasi, A., Urbina, S. (1997). Psychological testing.…

Innovations associated with gas and oil drilling technology, including new hydraulic fracturing and horizontal drilling techniques, have recently led to dramatic boomtown development in many rural areas that have endured extended periods of economic decline. The Marcellus Shale play, one of the world's largest gas-bearing shale formations, lies…

The Florida College and Career Readiness Initiative is a statewide policy that mandates college placement testing of 11th-graders who meet high school graduation criteria but are unlikely to meet college readiness criteria. Students who score below college-ready on the Postsecondary Education Readiness Test (PERT) are required to take math and…

States and districts across the country are grappling with how to incorporate assessments of student learning into their teacher evaluation systems. Sophisticated statistical models have been proposed to estimate the relative value individual teachers add to their students' assessment performance (hence the term teacher "value-added" measures).…

There is much debate over the impact of high stakes testing as well as a growing body of research focused on both the intended and unintended consequences of these tests. One claim of both the popular media and education researchers is that high stakes tests have led to curricular narrowing--the idea that school time is increasingly allocated to…
