We propose a hierarchical Bayesian model for analyzing multi-site experimental fMRI studies. Our method takes the hierarchical structure of the data (subjects are nested within sites, and there are multiple observations per subject) into account and allows for modeling between-site variation. Using posterior predictive model checking and model…

Linking administrative data records for the same individuals across services and over time offers a powerful, population-wide resource for child maltreatment research that can be used to identify risk and protective factors and to examine outcomes. Multistage de-identification processes have been developed to protect privacy and maintain…

A primary goal of assessment is to deliver truthful and clear information that can be used to inform and improve outcomes. Although there are multiple ways to achieve this goal, common approaches can be broken down into two major categories: (1) direct assessment; and (2) indirect assessment. Indirect assessment typically relies on general…

Background: Cross-cultural studies contribute to engineering education as a globally interconnected field. The methodological challenges posed by research across cultural boundaries must be explored to ensure the quality of such studies. Purpose: This article explores challenges and opportunities for insight by examining the effects of…

This mixed method study mainly explored how the extent of pre-service chemistry teachers' understanding of the particle nature of matter (PNM) affects their understanding of solution chemistry in the context of multirepresentational (MR) instruction. The ultimate goal was to describe the levels of understanding of specific solution chemistry…

With the expansion of service-learning has come a concomitant growth in research related to all the stakeholders involved with this pedagogy--students, faculty, community, and higher education institutions. However, no studies have examined the use of service-learning by a strong segment of college instructors--graduate students. To address the…

No scales currently exist that measure variability in the insight experience. Two scales were created to measure two factors hypothesized to be key drivers of the insight experience: insight radicality (i.e., perceived deviation between previous and new problem representations) and restructuring experience (i.e., the subjective experience of the…

Based on the data collected from 5 prestigious creativity journals, research methodologies and methods of 612 empirical studies on creativity, published between 2003 and 2012, were reviewed and compared to those in gifted education. Major findings included: (a) Creativity research was predominantly quantitative and psychometrics and experiment…

The objective of this paper is to conduct comparative analysis about the views and practices of policy makers and researchers on the use of health systems evidence in policy making in selected Eastern Mediterranean countries. We analysed data from two self-reported surveys, one targeted at policy makers and the other at researchers. Results show a…

Data literacy is complex. When students investigate the natural world, they must be able to gather data, organize it in tables and spreadsheets, analyze it in context, and describe and interpret it--usually as evidence to support a scientific argument. These skills are echoed in the science and engineering practices of the "Next Generation…

There is widespread support for expanding access to universities for under-represented groups, such as students from lower socio-economic backgrounds and older students, because of the higher rates of return to university degrees. This study examines whether this assumption holds true for mature-aged graduates who have received their degrees in an…

This activity introduces the science of "forensic palynology": the use of microscopic pollen and spores (also called "palynomorphs") to solve criminal cases. Plants produce large amounts of pollen or spores during reproductive cycles. Because of their chemical resistance, small size, and morphology, pollen and spores can be…

In order to assess the status of the research base that informs "what works" for students with disabilities in higher education, it is necessary to conduct an examination of the methodologies used in the literature. The authors of the current study analyzed the methodological trends across the thirty-year lifespan of the "Journal of…

Older people suffer discrimination in the labour market, in that their chances of finding employment if they lose their jobs are small, and the longer someone is out of the labour market, the harder it is to return. Although they often do possess the technical and transferrable skills required, these are not always recognised. Those who remain in…

In a time of limited means and continued calls for higher student achievement, school leaders need to be wise in their use of resources. Earlier research has called for greater levels of teacher preparation, and, while many school districts provide greater compensation for teachers with graduate degrees, some districts have begun phasing out this…
