The violation of the assumption of local independence when applying item response theory (IRT) models has been shown to have a negative impact on all estimates obtained from the given model. Numerous indices and statistics have been proposed to aid analysts in the detection of local dependence (LD). A Monte Carlo study was conducted to evaluate…

The application of scientific data in the development and implementation of sound public policy is a well-established practice, but there appears to be less consensus on the nature of the strategies that can and should be used to incorporate research data into policy decisions. This paper describes the promise and the challenges of using research…

In spite of all of the technical progress in observed-score equating, several of the more conceptual aspects of the process still are not well understood. As a result, the equating literature struggles with rather complex criteria of equating, lack of a test-theoretic foundation, confusing terminology, and ad hoc analyses. A return to Lord's…

As part of our inquiry into how youth development and 4-H programming can affect the development of social capital for youth and for the community, we engaged youth in ripple mapping. Based on this information, we provide a typology of participation structures in youth development activities and the expected bridging and bonding social capital…

Creating structures to include young people's opinions and advice has been recognized as important for high-quality youth programs and services. Recent scholarship has begun to learn that most of these efforts are often symbolic rather than substantive. While continually advocated for, the practice is not widespread or well done. Using data…

Instrumentation available for teachers and students has changed considerably during the last 20 years. The data logger-sensor system has the advantage of taking reliable measurements over time with suitable sample rates. This experiment is not an open-ended investigation but an opportunity to explore the established relationship between the…

Purpose: Digital preservation (DP) is the term used to describe the processes that guarantee the accessibility of data in the long term. The high value of health information justifies the use of electronic health records and the DP of them. This paper aims to examine one of the economic aspects of DP, presenting a cost model proposal for DP in…

Data integration is a critical component of enterprise system integration, and XML data validation is the foundation for sound data integration of XML-based information systems. Since B2B e-commerce relies on data validation as one of the critical components for enterprise integration, it is imperative for financial industries and e-commerce…

Advances in technology now make it possible to capture detailed multimodal data about real-world everyday activity. Researchers have taken advantage of these advances to address questions about activity in more systematic and precise ways. Along with exciting opportunities to record data in ways that were not possible before, there are also…

Micceri (1989) examined the distributional characteristics of 440 large-sample achievement and psychometric measures. All the distributions were found to be nonnormal at alpha = 0.01. Micceri indicated three factors that might contribute to a non-Gaussian error distribution in the population. The first factor is subpopulations within a target…

The central goal of the field of second language acquisition (SLA) is to describe and explain how second language learners acquire the target language. In order to achieve this goal, SLA researchers work with second language data, which can take a variety of forms, including (but not limited to) such commonly used methods as naturalistic…

Data literacy is recognized as a critically important skill in today's society, but thinking with and about data is often ignored in K-12 curricula. The Thinking With Data (TWD) project advocates that data literacy is a skill that should be addressed in an interdisciplinary manner. This article provides an overview of the TWD curriculum for middle…

Today's important geo-spatial technologies, GIS (Geographic Information Systems), GPS (Global Positioning Systems) and Google Earth have been widely used in geography education. Transferring spatially oriented data taken by GPS to the GIS and Google Earth has provided great benefits in terms of showing the usage of spatial technologies for field…

The purpose of this document is to provide information on the calculations and data from the 2017-2018 Civil Rights Data Collection (CRDC) that were used to assess the findings in the related thematic briefs. Using the 2017-18 CRDC data, variables were selected to observe the enrollment and experiences of students with disabilities in different…
