Previous U.K. population-based studies have found associations amongst early speech and language difficulties, socioeconomic disadvantage and children's word-reading ability later on. We examine the strength of these associations in a recent U.K. population-based birth cohort. Analyses were based on 13,680 participants. Linear regression models…

In confirmatory factor analysis quite similar models of measurement serve the detection of the difficulty factor and the factor due to the item-position effect. The item-position effect refers to the increasing dependency among the responses to successively presented items of a test whereas the difficulty factor is ascribed to the wide range of…

At the 2015 "NARST: A Worldwide Organization for Improving Science Teaching and Learning Through Research" Annual International Conference, a group of scholars held an extended pre-conference workshop to discuss key challenges and future directions faced by argumentation researchers around the world. This wide-ranging group of…

This paper presents findings from a small exploratory study examining eight diversely qualified early childhood (EC) educators' understandings about belonging.

Schools often offer injury prevention (IP) programs, but little is known about the types of programs provided or how school nurses decide which to choose. Nurses in the Missouri School Health Services Staffing Survey Database were sent a survey in spring, 2011, to describe school-based IP efforts being offered. A multivariate linear regression was…

This study examined how teachers read cases in a professional development academy for reading teachers. It drew on reading theory, particularly Tierney and Pearson's (1981) work on "text-based" and "reader-based" readings of traditional print-based text, to analyze conversations about cases where a specific focus on pedagogical…

Education is undergoing various transformations due to new data-driven educational technologies and the management of educational data through data infrastructures. These technologies are frequently promoted to parents and the profession as being 'revolutionary' because they represent a new generation of learning. While computer adaptive tests may…

Purpose of the Study: Missing data are a common problem encountered while implementing measurement instruments. Yet the extent to which reliability, validity, average discrimination and difficulty of the test results are affected by the missing data has not been studied much. Since it is inevitable that missing data have an impact on the…
