The purpose of this paper is to extend and evaluate methods of "Bayesian historical borrowing" applied to longitudinal data with a focus on parameter recovery and predictive performance. Bayesian historical borrowing allows researchers to utilize information from previous data sources and to adjust the extent of borrowing based on the…

The purpose of this National Assessment of Educational Progress (NAEP) Achievement Levels Validity Argument Report is to synthesize evidence currently available to address the validity of the interpretations and uses of the NAEP Achievement Levels. Validity is the extent to which theory and evidence supports or refutes proposed and enacted test…

While education is often talked about as a standalone system, most people experience education as just one part of their broader lives. Schools do not exist in siloes, but serve as a place where people and policy overlap and intersect. The implication of this is that while what happens inside of school buildings is incredibly important, such as…

This research empirically evaluates data sets from the National Center for Education Statistics (NCES) for design effects of ignoring the sampling design in weighted two-level analyses. Currently, researchers may ignore the sampling design beyond the levels that they model which might result in incorrect inferences regarding hypotheses due to…

Reading development in students who are second language learners (SLLs) has been a concern of many educators. It is important to understand reading development in students who are SLLs to effectively support their reading development. The dissertation consists of two studies, presented in two stand-alone manuscripts, that aimed to deepen our…

This study examines the pattern and extent of actual vs. perceived math achievement gaps (test scores vs. self-ratings) among Koreans, Korean-American immigrants and Korean-American natives. The study links TIMSS 2007 8th grade math data and ECLS-K 2007 8th grade math data together for matched sample (Korean ethnicity) comparisons. In terms of…

In a recent paper, Reardon found that the relationship between family income and children's academic achievement grew substantially stronger in the 1980s and 1990s in the United States. We provide an international context for these results by examining the income-achievement association in 19 other Organisation for Economic Co-operation and…
