This quantitative causal-comparative study investigated the growth performance scores of English learners in grades three through five in reading, mathematics, and science in four English language educational programs: English as Second Language (ESL), Transitional Bilingual Education (TBE), Dual-Language Immersion (DLI), and No Services. I used…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…

Developmental coordination disorder (DCD) has been classified as a specific learning disability, nonetheless the underlying cognitive mechanisms are still a matter of discussion. After a summary of the main hypotheses on the principal neuromotor causes of DCD, this study applies a causal model framework to describe the possible coexistence of more…

Background: The connection between childhood violence exposure and antisocial behavior in adolescence has received much attention and has important implications for understanding and preventing criminal behavior. However, there are a limited number of well-designed prospective studies that can suggest a causal relationship, and little is known…

Background: We examined whether staff attributions, emotions and helping behaviours in reaction to "real" incidents of challenging behaviour (CB) exhibited by children with intellectual disabilities were different from reactions to "vignettes". We also examined whether these reactions are congruent with that predicted by attribution theory.…

Background: Recent studies suggest that the association between maternal age at childbearing (MAC) and children's disruptive behaviors is the result of family factors that are confounded with both variables, rather than a casual effect of environmental factors specifically related to MAC. These studies, however, relied on restricted samples and…

Studies suggest that the oral narratives of children with attention deficit hyperactivity disorder (ADHD) are less organized than those of typically developing peers. Many studies, however, do not account for children's language abilities. Because language impairment (LI) is a frequent comorbid condition in children with ADHD, this exploratory…

An analytical approach was employed to compare sensitivity of causal effect estimates with different assumptions on treatment noncompliance and non-response behaviors. The core of this approach is to fully clarify bias mechanisms of considered models and to connect these models based on common parameters. Focusing on intention-to-treat analysis,…

Three experiments examined development of perceptual causality in 3- to 9-year-olds. Findings indicated that participants of all ages assigned contact events (A moves toward B, which moves upon contact) to the physical domain and non-contact events (B moves before contact) to the psychological domain. Participants chose causality more often for…

Assessed 8- to 16-year-olds of 64 mothers with recurrent unipolar or bipolar affective disorders, chronic medical illness, or no disorder. Results supported a model in which children's outcomes 6 months later were caused by maternal functioning and characteristics of the child. (RH)

Two cause indicator models were formulated to link items of the Home Observation for Measurement of the Environment--Short Form to the Peabody Picture Vocabulary Test--Revised. These models were tested with data from the National Longitudinal Survey of Youth (506 and 345 children), and a final model was developed. (SLD)

Examined developmental differences in evidence evaluation skills among school children, non-college educated adults, and college students, utilizing plant growth variables. Found that children were more strongly influenced by prior beliefs and missing data than were the two adult groups. Age and educational differences were found in the…
