Background: Individuals with Down syndrome generally show a floor effect on Wechsler Scales that is manifested by flat profiles and with many or all of the weighted scores on the subtests equal to 1. Method: The main aim of the present paper is to use the statistical Hessl method and the extended statistical method of Orsini, Pezzuti and Hulbert…

Academic advisors need training and development in three critical components for effective practice: conceptual (students and institutional context), informational (laws, policies, procedures) and relational (interpersonal skills). Yet, the relational component is often neglected. Limited research explores the relational component and its presence…

The Rosenberg Self-Esteem Scale was administered with a 1-4, 1-5, or 0-100 scale to 819 participants, to compare score interpretations across the different versions. A rating scale utility analysis revealed that the categories in the 101-point scale were used inconsistently; based on the analysis, adjacent categories were collapsed resulting in a…

Purpose: This study examined the relationship between measurements derived from spontaneous speech and participants' scores on the Montreal Cognitive Assessment. Method: Participants (N = 521) aged between 64 and 97 years completed the cognitive assessment and were prompted to describe an early childhood memory. A range of acoustic and linguistic…

Purpose: This study builds a stochastic model of a discrete-time Markov chain (DTMC) that fits well with a dataset of professional playing records. Methods: The point-by-point dataset of Men's single matches played in the Association of Tennis Professionals (ATP) tour from 2011 to 2015 is analyzed. A long-debated assumption on the…

Ramsay and Wiberg used a new version of item response theory that represents test performance over nonnegative closed intervals such as [0, 100] or [0, n] and demonstrated that optimal scoring of binary test data yielded substantial improvements in point-wise root-mean-squared error and bias over number right or sum scoring. We extend these…

Evidence of the internal consistency of standard-setting judgments is a critical part of the validity argument for tests used to make classification decisions. The bookmark standard-setting procedure is a popular approach to establishing performance standards, but there is relatively little research that reflects on the internal consistency of the…

Recently, a large number of vocabulary tests have been made available to language teachers, testers, and researchers. Unfortunately, most of them have been launched with inadequate validation evidence. The field of language testing has become increasingly more rigorous in the area of test validation, but developers of vocabulary tests have…

This article compares cut scores from two variations of the Hofstee and Beuk methods, which determine cut scores by resolving inconsistencies in panelists' judgments about cut scores and pass rates, with the Angoff method. The first variation uses responses to the Hofstee and Beuk percentage correct and pass rate questions to calculate cut scores.…

EPS contracted with LXD Research, a third-party research company, to examine the relationship between progress in S.P.I.R.E. and student reading outcomes at Martin County School District in Florida. LXD Research analyzed 192 students from grades 3-5 in 13 elementary schools who use S.P.I.R.E./i.S.P.I.R.E. reading intervention that uses an…

Background: Enhanced uptake of systematic reviews that use qualitative comparative analyses (QCA) requires knowing how end-users interpret such findings. The study purpose was to identify effective approaches to communicating results from a QCA within a systematic review. Methods: Sequential exploratory mixed methods design; thematic analysis of…

Creativity is a fundamental human accomplishment from scientific advances to composing music. The left dorsolateral prefrontal cortex (DLPFC) and inferior frontal gyrus (IFG) are important metacontrol hubs in flexibility and persistence brain states, respectively. Those hubs are related to divergent thinking, insight problem-solving, and…

To evaluate how Advanced Placement (AP) courses affect college-going, we randomly assigned the offer of enrollment into an AP science course to over 1,800 students in twenty-three schools that had not previously offered the course. We find no AP course effects on students' college entrance exam scores (SAT/ACT). As expected, AP course-takers are…

Purpose: Children and adolescents who stutter may be at risk of elevated anxiety and depression symptoms, although studies have indicated variability in reported internalizing symptoms in this population. This study considers the association between anxiety and depression symptoms and stuttering, as well as child, family, and contextual factors…

Background: Many amateur singers enjoy singing in choirs. They are likely to lack the training and expertise of professional singers and this may have an impact on their vocal health. Aims: To assess the experiences of amateur singers, their use of warm-up and cool-down sessions, their vocal health, their sources of help and advice and their…
