A new report titled "The Long-Term Impacts of Teachers" concludes that teachers whose students tend to show high gains on their test scores (called "high value-added teachers") also contribute to later student success in young adulthood, as indicated by outcomes such as college attendance and future earnings. To support this claim, it is not…

Objective: This article evaluates the diagnostic utility of a self-report screening tool for adults based on "Diagnostic and Statistical Manual of Mental Disorders" (4th ed.; "DSM-IV") ADHD criteria. Method: Children with speech/language (S/L) impairment and typically developing controls had ADHD symptoms rated by parents and…

This study investigates aspects of validity of an alternative measure of productive vocabulary. Lex30, developed by Meara and Fitzpatrick, is a word association task that claims to give an indication of productive vocabulary knowledge. Previous studies of Lex30 have assessed test-retest reliability, performance against native speaker norms,…

This article presents a review of the Children's Organizational Skills Scales (COSS) which were designed to assess how children organize their time, materials, and actions to accomplish important tasks at home and school. The scale quantifies children's skills in organization, time management, and planning (OTMP). The COSS is a multi-informant…

Knowledge of the equal sign as an indicator of mathematical equality is foundational to children's mathematical development and serves as a key link between arithmetic and algebra. The current findings reaffirmed a past finding that diverse items can be integrated onto a single scale, revealed the wide variability in children's knowledge of the…

Clinical competence is a multidimensional concept and encompasses a variety of skills including procedural, problem-solving and clinical judgement. The initial stages of postgraduate medical training are believed to be a particularly important time for the development of clinical skill competencies. This study reports on an evaluation of a…

The aim of the current study is twofold: (a) to investigate the rates at which researchers assess and report on the psychometric properties of the measures they use in their research and (b) to examine whether or not researchers appear to be generally employing sound/unsound rationales when it comes to how they conduct test evaluations. Based on a…

In this article, two professors retake the college-entrance exam and arrive at very different conclusions about its performance. Even though Christopher Harper has worked as a college professor for 15 years, he decided last winter to take the SAT and ACT examinations that his students needed to enter the institution where he teaches, Temple…

Common rates employed in classificatory testing are the true positive rate (TPR), false positive rate (FPR), positive predictive power (PPP), and negative predictive power (NPP). FPR and TPR are estimated from research samples representing populations to be distinguished by classificatory testing. PPP and NPP are used by clinicians to classify…

Validity studies with the Reynolds Intellectual Ability scales (RIAS) indicated that RIAS composite intelligence index (CIX) and verbal intelligence index (VIX) scores have moderate-to-high correlation with comparable scores on other instruments. The authors of the RIAS described the VIX scale as a measure of crystallized ability and the nonverbal…

Previous research has found relationships between measures of creativity and Vocational Interests, especially the artistic type. To partially examine the validity of a new self-report measure of creativity, 115 college students were administered the Vocational Preference Inventory (Form C) (VPI-C; Holland, 1985; Lowman & Schurman, 1982) and…

The assessment of cognitive abilities, whether it is for purposes of basic research or applied decision making, is potentially susceptible to both facilitating and debilitating influences. However, relatively little research has examined the degree to which these factors might moderate the criterion-related validity of cognitive ability tests. To…

This study examined the acceptability, reliability, and validity of the Arabic translated version of the Rapid Automatized Naming and Rapid Alternating Stimulus Tests (RAN/RAS; Wolf & Denckla, 2005) for Jordanian students. RAN/RAS tests are a vital assessment tool to distinguish good readers from poor readers. These tests have been…

Problem statement: A significant decrease has been recently observed in the resources for education allocated from Turkey's public budget, despite the increasing number of teachers and students. It is possible to better observe this trend at the primary education stage, which is compulsory and free at public schools through law no 42 under the…

The nutrition environment in schools can influence the risk for childhood overweight and obesity, which in turn can have life-long implications for risk of chronic disease. This dissertation aimed to examine the nutrition environment in primary public schools in California with regards to the amount of nutrition education provided in the…
