Mark B. Pacheco; F. Chris Curran; Lelydeyvis Boza; Amber W. Deig; Katharine T. Harris; Tiffany S. Tan – TESOL Quarterly: A Journal for Teachers of English to Speakers of Other Languages and of Standard English as a Second Dialect, 2024
This study contributes to a growing body of scholarship at the intersection of bilingual education and education policy and examines reclassification, or the transition out of formal English language services in schools, as one potential lever in accelerating or decelerating multilingual learners' science learning. More specifically, it traces…

Nam, Yeji; Hong, Sehee – Educational and Psychological Measurement, 2021
This study investigated the extent to which class-specific parameter estimates are biased by the within-class normality assumption in nonnormal growth mixture modeling (GMM). Monte Carlo simulations for nonnormal GMM were conducted to analyze and compare two strategies for obtaining unbiased parameter estimates: relaxing the within-class normality…

McConnell-Nzunga, J.; Naylor, P. J.; Macdonald, H.; Rhodes, R. E.; Hofer, S. M.; McKay, H. – Measurement in Physical Education and Exercise Science, 2018
Body mass index is a common proxy for proportion of body fat. However, body mass index may not classify youth similarly across ages and ethnicities. We used sex- and ethnic-specific receiver operating characteristic curves to determine how obesity classifications compared between body mass index and dual energy x-ray absorptiometry-based body fat…

Lima, Rodrigo Antunes; Bugge, Anna; Pfeiffer, Karin Allor; Andersen, Lars Bo – Research Quarterly for Exercise and Sport, 2017
Purpose: The purpose of this study was to analyze tracking and stability of motor coordination in children from age 6 years to ages 9 and 13 years. Method: Data were from the Copenhagen School Child Intervention Study. Motor coordination (MC) was measured using the körperkoordinationstest für Kinder (KTK) test. The crude performance score on every…

We integrated multiple behavioural and developmental measures from multiple time-points using machine learning to improve early prediction of individual Autism Spectrum Disorder (ASD) outcome. We examined Mullen Scales of Early Learning, Vineland Adaptive Behavior Scales, and early ASD symptoms between 8 and 36 months in high-risk siblings (HR; n…

Ilana Umansky; Hanna Dumont – Annenberg Institute for School Reform at Brown University, 2019
Prior research has shown that EL classification is consequential for students, however, less is known about how EL classification impacts students' outcomes. In this study, we examine one hypothesized mechanism: teacher perceptions. Using nationally-representative data (ECLS-K:2011), we use coarsened exact matching to estimate the effect of EL…

Pritzker, J. B.; Bradach, Jeffrey L.; Kaufmann, Katherine – Bridgespan Group, 2015
When every child has the opportunity to meet his or her full potential, families, communities, and the nation's economic future strengthens. Remarkably, one in four American children come from low-income families and enter kindergarten not ready to learn and, as a result, fall behind from the very start. The nation pays a heavy price through…

Song, Shuang; Su, Mengmeng; Kang, Cuiping; Liu, Hongyun; Zhang, Yuping; McBride-Chang, Catherine; Tardif, Twila; Li, Hong; Liang, Weilan; Zhang, Zhixiang; Shu, Hua – Developmental Science, 2015
In this 8-year longitudinal study, we traced the vocabulary growth of Chinese children, explored potential precursors of vocabulary knowledge, and investigated how vocabulary growth predicted future reading skills. Two hundred and sixty-four (264) native Chinese children from Beijing were measured on a variety of reading and language tasks over…

Wren, Yvonne; Miller, Laura L.; Peters, Tim J.; Emond, Alan; Roulstone, Sue – Journal of Speech, Language, and Hearing Research, 2016
Purpose: The purpose of this study was to determine prevalence and predictors of persistent speech sound disorder (SSD) in children aged 8 years after disregarding children presenting solely with common clinical distortions (i.e., residual errors). Method: Data from the Avon Longitudinal Study of Parents and Children (Boyd et al., 2012) were used.…

Tomanovic, Smiljka – Journal of Youth Studies, 2012
The article deals with the formation of the social biographies of young people through the interplay of structure and agency. The aim is to provide a grounded typology of patterns of young people's agency within the process of shaping social biographies. The structural context addressed in the article consists of family resources and habitus. The…

Swanson, H. Lee – Journal of Learning Disabilities, 2011
This longitudinal study assessed (a) whether performance changes in working memory (WM) as a function of dynamic testing were related to growth in reading comprehension and (b) whether WM performance among subgroups of children with reading disabilities (RD; children with RD only, children with both reading and arithmetic deficits, and low verbal…

San Martin Martinez, Conchi; Boada i Calbet, Humbert; Feigenbaum, Peter – Cognitive Development, 2011
To further investigate the possible regulatory role of private and inner speech in the context of referential social speech communications, a set of clear and systematically applied measures is needed. This study addresses this need by introducing a rigorous method for identifying private speech and certain sharply defined instances of inaudible…

Peterson, Carole – Journal of Experimental Child Psychology, 2011
Injured children (N=145 between 2 and 13 years of age) were recruited from a hospital emergency room and were interviewed about the injury event soon afterward and then twice more at yearly intervals. Their transcripts were coded three ways: completeness of overall structural components of a prototypical injury event (e.g., who, when, where),…

MacWilliams, Bruce A.; Johnson, Barbara A.; Shuckra, Amy L.; D'Astous, Jacques L. – Developmental Medicine & Child Neurology, 2011
Aim: To compare function and gait in a group of children older than most children who received selective dorsal rhizotomy (SDR) with age- and function-matched peers who received either orthopedic surgery or no surgical intervention. Method: A retrospective study examined ambulatory children with diplegic cerebral palsy, aged between 10 years and…

Rao, Patricia A.; Landa, Rebecca J. – Autism: The International Journal of Research and Practice, 2014
Autism spectrum disorder and attention deficit hyperactivity disorder are neurodevelopmental disorders that cannot be codiagnosed under existing diagnostic guidelines ("Diagnostic and Statistical Manual of the American Psychiatric Association," 4th ed., text rev.). However, reports are emerging that attention deficit hyperactivity…
