Education is frequently cited as the path to an informed citizenry with an optimistic economic outlook. Consequently, it is not surprising that there is an initiative to extend postsecondary educational opportunities to underserved and at-risk demographics. A challenge facing educators that serve at-risk populations is the tension between…

This study investigated pre-service mathematics teachers' (PST), who are going to teach middle grade mathematics (grade 5-8), understanding of inclusion relationships of quadrilaterals. In addition to describing PSTs' understanding of inclusion relations of quadrilaterals; it was also aimed to document the development of PSTs' understanding of…

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…

Purpose: The purpose of this study is to identify and examine findings from empirical research regarding organizations' talent development (TD) strategies, taking into consideration the countries in which the studies were conducted and the TD-approach organizations adopted, and recognize the positive outcomes of TD implementation, as well as…

Data models built for analyzing student data often obfuscate temporal relationships for reasons of simplicity, or to aid in generalization. We present a model based on temporal relationships of heterogeneous data as the basis for building predictive models. We show how within- and between-semester temporal patterns can provide insight into the…

Information communications technologies (ICTs) like laptops, smartphones and portable storage devices facilitate travel, communication and documentation for researchers who conduct fieldwork. But despite increasing awareness about the ethical complications associated with using ICTs among journalists and humanitarians, there are few reflections on…

School discipline and school safety are primary areas of concern for school administrators. This article summarizes the research literature regarding suspension in response to nonviolent and subjective offenses for racial/ethnic minorities. Steps that administrators can follow in applying a root cause analysis with a focus on school practices are…

In this study, it is aimed to investigate the impact of different missing data handling methods on the detection of Differential Item Functioning methods (Mantel Haenszel and Standardization methods based on Classical Test Theory and Likelihood Ratio Test method based on Item Response Theory). In this regard, on the data acquired from 1046…

We propose a general cognitive diagnosis model framework to diagnose mental disorders using item scores obtained from clinical measurement instruments. This framework can be used to validate the extent to which the items measure the specific disorders. The method is illustrated using data obtained with the Dutch version of Millon Clinical…

This paper demonstrates a dynamic, collaborative, and dialogic strategy for guiding students (and experienced researcher teams) through rudimentary forms of visual analysis using draw-and-write datasets. The approach identifies five sequential stages of the visual analysis process and further delineates twenty activities therein. Akin to the…

Departments and programmes in higher education are required to participate in an increasing number of programme, course and student assessments. These assessment requirements are also opportunities to develop student skills related to scientific literacy and research, if students are included in the process of developing, administering and…

Grounded in the concept of organizational demography, the authors investigate various demographic, precollege, and socioeconomic student-level attributes that universities readily house, and use them to create customized early warning tools to advance students' academic success. Upon a review of prior studies of sociodemographic influences in…
