A separate full report also was published. Austin Independent School District served 5,450 pre-K students in 2009-2010. Approximately 70% of sampled English-speaking pre-K students and 74% of sampled Spanish-speaking pre-K students had faster than the expected growth rate on an assessment of receptive vocabulary.

Since boys are more commonly diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) than girls, the majority of theories and published research studies of ADHD have been based on samples comprised primarily (or exclusively) of boys. While psychosocial impairment in girls with ADHD is well established, the neuropsychological and…

In his testimony before the Joint Economic Committee of the United States Congress, the author discusses what he considers to be the underlying question concerning issues of early childhood education: How to invest in preschool programs so that they have a reasonable chance of being a success. The testimony takes the form of a series of questions…

The aim of this study was to explore the extent to which the characteristics of two teaching interventions can bring about cognitive progress in preschoolers with regard to the factors rolling friction depends on, when it is applied to an object that is freely rolling on a horizontal surface. The study was conducted in three phases: pre-test,…

This article introduces the special section on child and adolescent mental health research in the context of Hurricane Katrina. We outline the purpose and intent of the special section and present an integrative perspective based on broad contextual theories of human development with which to think about the impact of disasters like Katrina. The…

The authors show how teachers can use nature explorations as a personal guide in implementing early learning standards. They describe five outdoor experiences of children in age groups ranging from 20 months to 5 years. A chart specifies which of the Nebraska state learning guidelines and Creative Curriculum goals the experiences meet, across the…

This paper examines the effects of different child-care arrangements on children's cognitive and social proficiencies at the start of kindergarten. Using data from the Early Childhood Longitudinal Study, we identify effects using OLS, matching and instrumental variables estimates. Overall, center-based care raises reading and math scores, but has…

This article reviews the research literature on psychosocial treatments for preschool-aged children with Attention-Deficit Hyperactivity Disorder (ADHD) in the context of the developmental and contextual needs of this population (e.g., increased parenting demands, differences in classroom structure, and the child's emerging developmental…

We investigated whether the tendency to imitate or emulate is influenced by the availability of causal information, and the amount of information available in a display. Three and 5-year-old children were shown by either a live or video model how to obtain a reward from either a clear or an opaque puzzle box. Some of the actions in the sequence…

Although "hindsight bias" (the "I knew it all along" phenomenon) has been documented in adults, its development has not been investigated. This is despite the fact that hindsight bias errors closely resemble the errors children make on theory of mind (ToM) tasks. Two main goals of the present work were to (a) create a battery of hindsight tasks…

Head Start is a federally funded preschool program for poor children designed to help close the gap between those children and their more advantaged peers before they begin public schooling. Given that Head Start appears to have positive long-run impacts on its recipients, a natural and important next question to ask is: What are the channels…

This large-scale study describes what children know and can do when they start school in Scotland. The description became possible because a third of Scottish Authorities are involved in a single, broadly based, on-entry baseline assessment of children. The study also looked at variations by home background, sex, age and pre-school experience…

The final report reviews accomplishments of an outreach project designed to provide technical assistance and training to early childhood programs for handicapped children. The project features the Cognitively Oriented Preschool Curriculum, a developmental approach based on Piagetian theory and explained to build on the child's accomplishments. A…

Developmental stages in causal reasoning and causative expression are outlined to provide comparison with preschool handicapped children. Three stages within the preschool range are defined in terms of changes in causal schemes, field of centration, and experimental attitude and skills. Suggestions for assessment and special education are made.…
