Over the past decade, the National Center for Research on Gifted Education (NCRGE), funded by the Jacob K. Javits Gifted and Talented Students Education Program, has conducted large-scale, multi-method studies to improve equity in the identification of and instructional support for gifted students. NCRGE has identified barriers and promising…

The extent to which Theory of Mind (ToM) performance is influenced by cultural and gender differences remains a subject of debate. A sample of 324 Dutch and 511 Italian children (52% boys; 2.8-11.7 years; 50% boys; 2.6-10.3 years; respectively) was administered the ToM Storybooks. Analysis focused on indicators of nonlinearity: moving standard…

Conditions influencing 328 students' (Grades 6-8) preferences for collaborating or working alone on challenging projects were investigated, as well as their potential interactions with ability, grade and sex. Each student completed the Cognitive Abilities Test (Form 7) and Project Context Survey. No overall preference for individual or…

Solving word problems involving 'Time' is an important skill but poor mastery of the skill among elementary students has often been reported in the literature. In addition, the available diagnostic tools in the literature might be less efficient for identifying the various errors made by many students in solving word problems. Thus, an online…

Here, intelligence is taken to mean scores from psychometric tests of cognitive functions. This essay describes how cognitive tests offer assessments of brain functioning--an otherwise difficult-to-assess organ--that have proved enduringly useful in the field of health and medicine. The two "consequential world problems" (the phrase used…

The factor structure, the concurrent validity, and test-retest reliability of the Czech translation of the Gifted Rating Scales-School Form [GRS-S; Pfeiffer, S. I., & Jarosewich, T. (2003). "GRS (gifted rating scales) - manual." Pearson] were evaluated. Ten alternative models were tested. Four models were found to exhibit acceptable…

Background: Several studies have reported that inservice and preservice teachers hold narrow and stereotypical perceptions of engineer and engineering. However, only a few studies attempted to examine interventions which improve their perceptions. Purpose: This study aimed to explore the preservice science teachers' (PSTs) perceptions of engineer…

Echocardiographers are highly specialised, skilled practitioners who play a critical role in medical imaging diagnostics. Yet, little is known about the cognitive and perceptual attributes of experts within this domain. This study was designed to examine the role of individual differences in expertise. Specifically, the contribution of a domain…

The paper reports a study that focussed on investigating the effectiveness of Toulmin's argument pattern (TAP) within Think-Read-Group-Share-Reflect (TRGSR) scientific argumentation strategy on higher secondary students' critical thinking. A quasi-experimental, pretest-posttest-control group design was deployed. The subjects were 50 twelfth grade…

This study analyzes the Wisconsin Card Sorting Test-Learning Potential (WCST-LP) in children with Autism Spectrum Disorder (ASD) versus children with typical development (TD). Its main aim was to assess: the test's construct validity; the effect of IQ on its pretest and LP scores; and whether the WCST-LP held any relationship to cognitive/EF and…

The measurement of perfectionistic cognitions has recently caused disagreement among researchers. Flett, Hewitt, Blankstein, and Gray proposed that perfectionistic cognitions are unidimensional. However, after re-examining the factor structure of the instrument used to measure perfectionistic automatic thoughts (Perfectionism Cognitions Inventory…

This mixed methods study focused on gifted education screening practices in North Carolina. Specific focus was on the practice of universal screenings using the Cognitive Abilities Test (CogAT) and test preparation measures conducted by one school district. The study collected and analyzed data from regular elementary education and elementary AIG…

Grounded in the bioecological model of human development and attachment theory, this study examined whether the proportion of time children spend in activity settings in the kindergarten classroom moderated the relationship between teacher-child relationship quality and children's kindergarten academic and social-emotional outcomes. Participants…

Background and Aims: In educational measurement, performance assessments occupy a niche for offering a true-to-life format that affords the measurement of high-level cognitive competencies and the evidence to draw inferences about intellectual capital. However, true-to-life formats also introduce myriad complexities and can skew if not outright…

For item selection in cognitive diagnostic computerized adaptive testing (CD-CAT), ideally, a single item selection index should be created to simultaneously regulate precision, exposure status, and attribute balancing. For this purpose, in this study, we first proposed an attribute-balanced item selection criterion, namely, the standardized…
