Purpose: The purpose of this study was to determine the acute dose-response relationship of classroom exercise breaks with executive function and math performance in 9- to 12-year-old children by comparing 5-min, 10-min, or 20-min classroom exercise breaks to 10 min of sedentary classroom activity. Method: This study used a within-subjects…

Socioeconomic status (SES) is a well-known predictor of cognitive achievement and executive functioning, although the underlying cognitive mediating processes remain unclear. The authors analyze the association between different socioeconomic indicators and the executive functions (EF) of schoolchildren and the possible cognitive mediating factors…

Background: Presence of an autism spectrum disorder is a risk factor for development of self-injurious behaviour (SIB) exhibited by individuals with developmental disorders. The most salient SIB risk factors historically studied within developmental disorders are level of intellectual disability, communication deficits and presence of specific…

The response to intervention model (RTI) represents a promising framework for the early identification and prevention of learning and behavior problems for students struggling in school. If RTI is properly implemented, it should reduce unnecessary referrals and placements into special education, and increase the accuracy of special education…

A meta-analysis of 22 studies evaluating the relation of different assessments of IQ and intervention response did not support the hypothesis that IQ is an important predictor of response to instruction. We found an R[superscript 2] of 0.03 in models with IQ and the autoregressor as predictors and a unique lower estimated R[superscript 2] of 0.006…

When Congress passed the Individuals with Disabilities Education Improvement Act in 2004 (IDEIA 2004), local educational agencies (LEA) were permitted to use a Response-to-Intervention (RtI) approach for identifying children with possible learning disabilities for special education. Furthermore, IDEIA 2004 no longer required LEAs to establish an…

This examination of several programs intended to raise intelligence and prevent or cure mental retardation fails to reveal any evidence that they are effective. In view of the cycle of optimism and disillusionment that pervades the history of this field, caution and restraint are recommended. (Author/LMO)

This Education Policy Brief provides readers with a broad overview of Response to Intervention (RTI). Response to Intervention refers to an integrated, schoolwide method of service delivery across general and special education that promotes successful school outcomes for all students. This brief first discusses the impetus behind RTI, which stems…

A developmental cascade model linking competence and symptoms was tested in a study of a normative, urban school sample of 205 children (initially 8 to 12 years old). Internalizing and externalizing symptoms and academic competence were assessed by multiple methods at the study outset and after 7, 10, and 20 years. A series of nested cascade…

This book chronicles the evolution of the child welfare movement of the early 20th century into the science of child development, from both the national perspective and the perspective of the field's best-known research center, the University of Iowa's Child Welfare Research Station. The book first explores the child welfare movement as it evolved…
