The purpose of this study was to investigate a new way of evaluating interrater reliability that can allow one to determine if two raters differ with respect to their rating on a polytomous rating scale or constructed response item. Specifically, differential item functioning (DIF) analyses were used to assess interrater reliability and compared…

Play is central to children's learning and development in the early years, including the learning of mathematics. The aim of the present study was to explore how play skills are related to mathematical skills in toddlers by examining the correlations between different kinds of play skills and mathematical skills, and how level of play skills is…

The purpose of the study is to investigate if there is a difference between the performance results of the gymnasts receiving and not receiving modern dance education, which is applied to the rhythmic gymnasts in the category of junior. The experimental group included 10 rhythmic gymnasts competing in the category of junior in Antalyaspor Club…

Creativity is an understudied topic in elementary school mathematics research. Nevertheless, we argue that creativity plays an important role in mathematics, but that more research is needed to understand this relation. Therefore, this study aimed to investigate this relation, specifically between domain-general creativity, domain-specific…

Self-injurious behavior (SIB) is inherently problematic because it can lead to injuries, including those that are quite severe and may result in loss of function or permanent disfigurement. The current study replicated and extended Rooker et al. (2018) by classifying the physical characteristics of injuries across groups of individuals with…

This research examined correlation estimates between latent abilities when using the two-dimensional and three-dimensional compensatory and noncompensatory item response theory models. Simulation study results showed that the recovery of the latent correlation was best when the test contained 100% of simple structure items for all models and…

Feeling of loneliness is a matter that is commonly encountered among adolescents and young adults and should be taken into consideration. This study was conducted for the purpose of determining whether or not there was a correlation between the feeling of loneliness and burnout levels in university students. The purpose of the study is to…

The construct validity of the International Cognitive Ability Resource (ICAR) has yet to be investigated using a gold-standard individually administered intelligence battery. The present study used a convenience sample of 97 students to examine the respective relations between the ICAR16 and overall intelligence (g) and the Cattell-Horn-Carroll…

Speech and music emerge from a spectrum of nested motor and perceptual coordination patterns across timescales of brief movements to actions. Intuitively, this nested clustering in movements should be reflected in sound. We examined similarities and differences in multimodal, multiscale coordination of speech and music using two complementary…

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…

Objective: Food allergies are on the rise in the U.S. Factors associated with willingness and readiness to act in a food allergic emergency on a college campus are currently unknown. Participants: College students in one Catholic college enrolled during spring of 2017. Methods: A previously piloted survey was distributed by e-mail. Results: Four…

As an avid advocator of education reform in the 1850s, Emerson was long neglected in the history of American educational thought. This paper, through the investigation from four aspects, namely the Transcendental Educational Thought, the Puritanical Educational Thought, the Romantic Educational Thought, and the Confucian's Educational Thought,…

Carbohydrates, or in strictly chemical terms, polyhydroxy-aldehydes or ketones represent enormous structural diversity in terms of the arrangement of atoms in space, resulting in hundreds of stereoisomers. Although the chemical properties of most stereoisomers may not be very different, their metabolic fate and utilization in biological systems is…

Recurrent pain and school failures are common problems in children visiting the school nurses office. The overall aim of the current study was to investigate the relationship between recurrent pain and academic achievement in school-aged children. Literature was searched in seven electronic databases and in relevant bibliographies. Study…

This article describes an experience of collaborative work between scientists and preschool teachers in the format of a scientific congress of preschoolers in Chile. The participating preschool teachers evaluated the initiative positively based on: (1) it stimulates the preschool teachers to develop science teaching projects, (2) it makes visible…
