Lu, Yi – Journal of Educational Issues, 2016
To model students' math growth trajectory, three conventional growth curve models and three growth mixture models are applied to the Early Childhood Longitudinal Study Kindergarten-Fifth grade (ECLS K-5) dataset in this study. The results of conventional growth curve model show gender differences on math IRT scores. When holding socio-economic…

Kern, Justin L.; McBride, Brent A.; Laxman, Daniel J.; Dyer, W. Justin; Santos, Rosa M.; Jeans, Laurie M. – Grantee Submission, 2016
Measurement invariance (MI) is a property of measurement that is often implicitly assumed, but in many cases, not tested. When the assumption of MI is tested, it generally involves determining if the measurement holds longitudinally or cross-culturally. A growing literature shows that other groupings can, and should, be considered as well.…

Liu, Haiyan; Zhang, Zhiyong; Grimm, Kevin J. – Grantee Submission, 2016
Growth curve modeling provides a general framework for analyzing longitudinal data from social, behavioral, and educational sciences. Bayesian methods have been used to estimate growth curve models, in which priors need to be specified for unknown parameters. For the covariance parameter matrix, the inverse Wishart prior is most commonly used due…

Chmielewski, Anna K.; Reardon, Sean F. – AERA Open, 2016
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…

Little, Michael H. – AERA Open, 2016
Despite growing interest in the importance of nonacademic skills for student success, very few studies have examined the extent to which schools and teachers are associated with gains in these outcomes. This descriptive study adds to the nascent literature by examining the amount of school- and teacher-associated variation in kindergarten…

Cimpian, Joseph R.; Lubienski, Sarah T.; Timmer, Jennifer D.; Makowski, Martha B.; Miller, Emily K. – AERA Open, 2016
Studies using data from the Early Childhood Longitudinal Study--Kindergarten Class of 1998-1999 (ECLS-K:1999) revealed gender gaps in mathematics achievement and teacher perceptions. However, recent evidence suggests that gender gaps have closed on state tests, raising the question of whether such gaps are absent in the ECLS-K:2011 cohort.…

Little, Michael H.; Cohen-Vogel, Lora; Curran, F. Chris – AERA Open, 2016
Leveraging data from two nationally representative cohorts from the ECLS-K (Early Childhood Longitudinal Study--Kindergarten), we examine the types of transition practices that schools use to ease children's adjustment to formal schooling. The transition to kindergarten is a critical juncture in a child's life that entails a host of social,…

Reardon, Sean F.; Portilla, Ximena A. – AERA Open, 2016
Academic achievement gaps between high- and low-income students born in the 1990s were much larger than between cohorts born two decades earlier. Racial/ethnic achievement gaps declined during the same period. To determine whether these two trends have continued in more recent cohorts, we examine trends in several dimensions of school readiness,…

Kalil, Ariel; Ziol-Guest, Kathleen M.; Ryan, Rebecca M.; Markowitz, Anna J. – AERA Open, 2016
Numerous studies show large differences between economically advantaged and disadvantaged parents in the quality and quantity of their engagement in young children's development. This "parenting gap" may account for a substantial portion of the gap in children's early cognitive skills. However, researchers know little about whether the…

Bassok, Daphna; Finch, Jenna E.; Lee, RaeHyuck; Reardon, Sean F.; Waldfogel, Jane – AERA Open, 2016
This study compares the early life experiences of kindergarteners in 1998 and 2010 using two nationally representative data sets. We find that (a) young children in the later period are exposed to more books and reading in the home, (b) they have more access to educational games on computers, and (c) they engage with their parents more, inside and…

Grissom, Jason A.; Redding, Christopher – AERA Open, 2016
Students of color are underrepresented in gifted programs relative to White students, but the reasons for this underrepresentation are poorly understood. We investigate the predictors of gifted assignment using nationally representative, longitudinal data on elementary students. We document that even among students with high standardized test…

Schneider, Barbara; Saw, Guan; Broda, Michael – AERA Open, 2016
Forty years ago, the National Center for Education Statistics initiated the national longitudinal studies program in response to congressional concern for policy-relevant information on school-to-work transitions. This program has grown substantially, and not unexpectedly, questions have arisen about its usefulness and present operation. This…

Patrick, Susan Kemper – AERA Online Paper Repository, 2016
Ability grouping is a common educational practice utilized by elementary teachers during reading instruction. This study examines whether ability grouping operates as a form of educational stratification by examining the following research question: To what extent do student literacy skills, background characteristics, and prior group placement…

Lee, Jaekyung; Kim, Namsook – Online Submission, 2016
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…

Zhang, Zhiyong – Grantee Submission, 2016
Growth curve models are widely used in social and behavioral sciences. However, typical growth curve models often assume that the errors are normally distributed although non-normal data may be even more common than normal data. In order to avoid possible statistical inference problems in blindly assuming normality, a general Bayesian framework is…
