It is often hypothesized that prior knowledge strongly predicts learning performance. It can affect learning positively mediated through some processes and negatively mediated through others. We examined the relation between prior knowledge and learning in a meta-analysis of 8776 effect sizes. The stability of individual differences, that is, the…

Publication bias threatens meta-analysis validity. It is often assessed via the funnel plot; an asymmetric plot implies small-study effects, and publication bias is one cause of the asymmetry. Egger's regression test is a widely used tool to quantitatively assess such asymmetry. It examines the association between the observed effect sizes and…

The effects of different response option orders on survey responses have been studied extensively. The typical research design involves examining the differences in response characteristics between conditions with the same item stems and response option orders that differ in valence--either incrementally arranged (e.g., strongly disagree to…

Parents' executive functions (EFs), or cognitive skills facilitating thought and behavior management, are meaningful correlates of parenting behavior. EFs are theorized to support parents in inhibiting reactive responses, managing information during parent--child interactions, and adapting to novel developmental demands. Less effective EFs…

Thousands of education institutions worldwide rely on IELTS scores as criteria for accepting international students whose first language is not English. Individual studies have found varying degrees of strength of correlations and conflicting results between IELTS entry scores and subsequent academic success. These conflicting results were…

For institutions where English is the primary language of instruction, English assessments for admissions such as the Test of English as a Foreign Language (TOEFL) and International English Language Testing System (IELTS) give admissions decision-makers a sense of a student's skills in academic English. Despite this explicit purpose, these exams…

The Implicit Association Test (IAT) is increasingly used in developmental research despite minimal evidence of whether children's IAT scores are reliable across time or predictive of behavior. When test-retest reliability and predictive validity have been assessed, the results have been mixed, and because these studies have differed on many…

Proactive preliminary minimum sample size determination can be useful for the early planning stages of a latent variable modeling study to set a realistic scope, long before the model and population are finalized. This study examined existing methods and proposed a new method for proactive preliminary minimum sample size determination.

Problem Statement: The number of studies on the effect of educational leadership on several organizational outputs is increasing. The most popular topic to review within the framework of leadership is job satisfaction. In several studies, a positive correlation was found between leadership and job satisfaction. According to the two-factor theory…

The main purpose of this study was to review pivotal response training and examine the efficacy of pivotal response training for children with autism spectrum disorder. The other purposes of study were to (a) examine the characteristics of participants and components of the intervention in which pivotal response training was used; (b) determine…

Deficits in Theory of Mind (ToM)--the ability to interpret others' beliefs, intentions and emotions--undermine the ability of individuals with Autism Spectrum Disorder (ASD) to interact in socially normative ways. This study provides psychometric data for the Adult-Theory of Mind (A-ToM) measure using video-scenarios based in part on Happé's…

We describe our experience of using a modified version of the Cochrane risk of bias (RoB) tool for randomised and non-randomised comparative studies. Objectives: (1) To assess time to complete RoB assessment; (2) To assess inter-rater agreement; and (3) To explore the association between RoB and treatment effect size. Methods: Cochrane risk of…

Given the serious consequences of making ill-fated admissions and funding decisions for applicants to graduate and professional school, it is important to rely on sound evidence to optimize such judgments. Previous meta-analytic research has demonstrated the generalizable validity of the "GRE"® General Test for predicting academic…

The purpose of the current research was to investigate the relationship between preference for numerical information (PNI), math self-concept, and six types of statistics anxiety in an attempt to establish support for the nomological validity of the PNI. Correlations indicate that four types of statistics anxiety were strongly related to PNI, and…

Language test preparation has often been studied within the consequential validity framework in relation to ethics, equity, fairness, and washback of assessment. The use of independent and integrated speaking tasks in the "TOEFL iBT"® test represents a significant development and innovation in assessing speaking ability in academic…
