In this technical comment, we argue that Morgan et al.'s claim that there is no minority overrepresentation in special education is in error due to (a) sampling considerations, (b) inadequate support from previous and current analyses, and (c) their failure to consider the complexities of special education disproportionality. [For Morgan et al.'s…

Science, Technology, Engineering, and Math (STEM) education is considered critical and valid for the modern workforce which is strongly enveloped in technology. Therefore, it is imperative to reinforce science and math education and knowledge among students early in their educations. Despite this understanding, most research has focused on the…

This manual provides guidance and documentation for users of the longitudinal kindergarten-second grade (K-2) data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011). It mainly provides information specific to the second-grade rounds of data collection. Users should refer to the "Early Childhood…

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…

Prior nonexperimental studies have been used to conclude that children's reading and mathematics achievement bidirectionally influence each other over time, with strong paths from (a) early reading to later mathematics and (b) early mathematics to later reading. In the most influential study on the topic, the early math-to-later-reading path was…

Adam Wright, Michael A. Gottfried, and Vi-Nhuan Le demonstrate empirically that minority teachers have a positive impact on the "social-emotional development" of American minority kindergarten children. Their analyses of 2010-2011 data from the Early Childhood Longitudinal Study focus on measurable effects in four social and affective…

This study examines the application of the Simple View of Reading (SVR), a reading comprehension theory focusing on word recognition and linguistic comprehension, to English Language Learners' (ELLs') English reading development. This study examines the concurrent and predictive validity of two components of the SVR, oral language and word-level…

Duncan et al. (2007) presented a new methodology for identifying kindergarten readiness factors and quantifying their importance by determining which of children's developing skills measured around kindergarten entrance would predict later reading and math achievement. The main objectives of this paper are threefold: (a) provide new empirical…

The problem of disproportionality in special education is complex and requires an investigation of multiple factors related to racial, ethnic, linguistic, and socioeconomic backgrounds, school context, and family characteristics. Researchers have debated whether language minority (LM) students are under or overrepresented in special education, but…

Nonnormality of univariate data has been extensively examined previously (Blanca et al., 2013; Micceri, 1989). However, less is known of the potential nonnormality of multivariate data although multivariate analysis is commonly used in psychological and educational research. Using univariate and multivariate skewness and kurtosis as measures of…

Reading is a necessary skill in our modern society and is increasingly critical for success in our highly technological society. Yet many children from low-SES backgrounds struggle to develop reading proficiency (Lee, Grigg, & Donahue, 2007) and continuing concerns about this pervasive relationship has led to an increased focus on creating…

This brief report focusing on children' s kindergarten readiness i s the third in a series of reports describing data from the 2009 cohort of the Head Start Family and Child Experiences Survey (FACES 2009). Previous FACES 2009 reports described the characteristics of children and their families and programs as they entered Head Start in fall 2009…

Drawing on a sample of twin children from the Early Childhood Longitudinal Study, Birth Cohort (ECLS-B; Snow et al., 2009), the current study analyzed 2 of the most prominent predictors of externalizing behavioral problems (EBP) in children: (a) parental use of spankings and (b) childhood self-regulation. A variety of statistical techniques were…

Research Findings: Researchers and policymakers emphasize that early childhood is a critical developmental stage with the potential to impact academic and social-emotional outcomes (G. Conti & J. J. Heckman, 2012; J. J. Heckman, 2012; R. Murnane, I. Sawhill, & C. Snow, 2012). Although there is substantial evidence that children's early…
