Policymakers view parental involvement (PI) as a crucial component of school reform efforts, but evidence of its effect on student achievement is equivocal. Using the Early Childhood Longitudinal Study-Kindergarten Cohort dataset, we examined the long-term impact on student- and school-level achievement of three types of school-based PI: PI to…

This study examined the Chinese written composition development of elementary-grade students in relation to the simple view of writing. Measures of nonverbal reasoning ability, component skills of transcription (stroke sequence knowledge, word spelling, and handwriting fluency), oral language (definitional skill, oral narrative skills, and…

In recent years the use of the latent curve model (LCM) among researchers in social sciences has increased noticeably, probably thanks to contemporary software developments and the availability of specialized literature. Extensions of the LCM, like the the latent change score model (LCSM), have also increased in popularity. At the same time, the R…

This study tested a transactional model of reciprocal influences regarding students' peer experiences (peer acceptance, peer rejection, and friends' academic achievement) and students' academic achievement from middle childhood to early adolescence. This longitudinal model was tested on 452 students (198 girls), mostly Caucasian and French…

Because random assignment is not possible in observational studies, estimates of treatment effects might be biased due to selection on observable and unobservable variables. To strengthen causal inference in longitudinal observational studies of multiple treatments, we present 4 latent growth models for propensity score matched groups, and…

Longitudinal structural equation modeling was used to evaluate longitudinal relationships across adjacent grade levels 1 to 7 for levels of language in writing (Model 1, subword letter writing, word spelling, and text composing) or writing and reading (Model 2, subword letter writing and word spelling and reading; Model 3, word spelling and…

Many young children exhibit aggressive and disruptive behaviors at early ages. However, while aggressive behaviors are normative and serve as a way to communicate needs in the midst of developing verbal abilities, continued disruptive behavior can lead to stable or increasing levels of behavioral dysregulation, oppositionality and aggression.…

Multitrait-multimethod (MTMM) confirmatory factor models were combined with longitudinal structural equation models to examine trait and method stability over time. A longitudinal correlated-trait correlated-method (CT-CM) model allowed for the study of trait and method variance in observed scores over time. Longitudinal measurement invariance was…

This study investigated the structure and development of processes involved in "g." One hundred and forty children, about equally drawn among primary school grades 1-6 were examined by four types of Stroop-like speeded tasks addressed to processes of increasing complexity (i.e., speed of processing, perceptual discrimination, perceptual control,…

Purpose: In this study, the authors evaluated the contribution made by dialect shifting to reading achievement test scores of African American English (AAE)-speaking students when controlling for the effects of socioeconomic status (SES), general oral language abilities, and writing skills. Method: Participants were 165 typically developing…

This study is the second in a series of investigations attempting to clarify relationships between variables that impact on a young musician's ability to perform music (as assessed on a graded music examination). Consistent with studies on school academic subjects, our previous investigation demonstrated the importance of self-efficacy in…

The purpose of this study was to explore the relationship of three subskills associated with word decoding. The skills utilized for this study were phonological, rapid automatized naming (RAN), and orthographic processing. To do this, six separate models were utilized to define different ways that these three subskills (represented as factors)…
