This study explored the influence of the dynamic assessment of human--computer interactive games on children's language potential. Thirty-seven special children aged 3--7 years were selected to participate in the study. They were divided into three groups according to their scores on the Autism Behaviour Checklist: (1) a non-autism group, (2) a…

Recently, Bayesian diagnostic classification modeling has been becoming popular in health psychology, education, and sociology. Typically information criteria are used for model selection when researchers want to choose the best model among alternative models. In Bayesian estimation, posterior predictive checking is a flexible Bayesian model…

Curriculum development is critically important to the educational enterprise, yet we lack insight into if and how ideal design and development practices are enacted in organizations that create curricular programs and resources intended for large-scale implementation. This study identified essential elements of curriculum development practices…

Bayesian methods offer many advantages when applied to psychological research, yet they may seem esoteric to researchers who are accustomed to traditional methods. This paper aims to lower the barrier of entry for developmental psychologists who are interested in using Bayesian methods. We provide worked examples of how to analyze common study…

Popular item response theory (IRT) models are considered complex, mainly due to the inclusion of a random factor variable (latent variable). The random factor variable represents the incidental parameter problem since the number of parameters increases when including data of new persons. Therefore, IRT models require a specific estimation method…

Bacteria have developed a cell-to-cell communication system called quorum sensing (QS), allowing them to regulate group behavior and synchronize the expression of virulence factors, responsible for increasing their infection capacity and resistance to antimicrobials. Although the control of microbial infections through the inhibition of microbial…

Researchers continue to choose PCA in scale development and adaptation studies because it is the default setting and overestimates measurement quality. When PCA is utilized in investigations, the explained variance and factor loadings can be exaggerated. PCA, in contrast to the models given in the literature, should be investigated in…

This article delved into the realm of EFL assessment in Iraq by investigating the beliefs of Iraqi EFL teachers about assessment practices they employed in their classroom and determining whether there was any congruency between their beliefs and actual assessment practices. For this purpose, 140 experienced Iraqi EFL teachers were selected by…

As environmental challenges increase in scope and scale, new conceptualizations for environmental literacy are needed. Specifically, notions of environmental literacy must move from those at the individual level to those at the group, or community, level. However, the concept of community level environmental literacy is underdeveloped. In this…

The traditional system focuses excessively on physical skills and physical fitness assessment, with problems such as single indicator, static approach, subject limitation and inefficient data utilization, making it difficult to assess students in a comprehensive and fair manner. The rise of big data technology has brought about a turnaround, from…

The purpose of this study was to determine professional evaluators' perceptions of reflective practice (RP) and the extent and manner in which they engage in RP behaviors. Nineteen evaluators with 10 or more years of experience in the evaluation field were interviewed to explore our understanding and practice of RP in evaluation. Findings suggest…

Social cognition is a very important group of neurocognitive processes involved especially in social functioning; currently, the amount of research on this topic is increasing and suggests some considerations about its assessment, particularly in the child population. This article presents some of these considerations focussed on the theoretical…

As an educator, and a student myself, I believe that the current system of graded assessments used ubiquitously in education systems worldwide is quite flawed. Although certain issues arise in its implementation, a suitable alternative might be to consider gradeless assessments. Thus, rather than completely advocating for a change in the way…

Measures of learning speed (i.e., the amount of learning/cumulative time learner spends engaged in an intervention) are rarely included in research designed to evaluate and compare academic interventions. We build a case that includes analyses of learning speed metrics in academic intervention research can provide more useful information for…

Clinical supervisors are known to assess trainee performance idiosyncratically, causing concern about the validity of their ratings. The literature on this issue relies heavily on retrospective collection of decisions, resulting in the risk of inaccurate information regarding what actually drives raters' perceptions. Capturing in-the-moment…
