Few studies examine the classroom behavior of children with attention deficit hyperactivity disorder (ADHD) in comparison with classroom peers and which teaching formats best support classroom engagement. Observations (N = 312) of second- and fourth-grade students with ADHD and their randomly selected classroom peers were conducted using a…

The abilities of past and future episodic thinking develop hand in hand across the preschool years and are intimately connected in adults. Little is known, however, about the development of episodic thinking in middle childhood and how it is influenced by sociocultural factors. In the present study, one hundred sixty-seven 7- to 10-year-old…

Communication spontaneously initiated by infants at heightened risk (HR; n = 15) for autism spectrum disorders (ASD) is compared with that in low-risk (LR; n = 15) infants at 13 and 18 months of age. Infants were observed longitudinally during naturalistic in-home interaction and semistructured play with caregivers. At both ages, HR infants…

In an attempt to influence students' appreciation of the value of research, the authors introduced a multidimensional scaling activity in a section of introductory psychology. In two consecutive 80-minute classes, 32 students worked in pairs, categorizing 20 crimes on the basis of similarity and coding their partner's responses, and then worked in…

This study reexamined PowerPoint's potential to enhance traditional pedagogical practices in higher education. The study addressed (1) the conditions under which PowerPoint meets students' needs in typical lecture-based classrooms, (2) whether professors consider PowerPoint-based lectures more effective than lectures supported by material on…

This manual provides guidance and documentation for users of the longitudinal kindergarten-fourth grade (K-4) data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011). It mainly provides information specific to the fourth-grade round of data collection. The first chapter provides an overview of the…

School gardening has become increasingly popular as a context for learning in which children construct new knowledge, learn cultural and societal values related to ecological awareness, and develop and practice authentic or real-world skills (Blair, 2009; Bowker & Tearle, 2007). The present research was a longitudinal case study of children's…

Previous work leaves open the question of whether children with autism spectrum disorders aged 6-12?years have delay in producing gestures compared to their typically developing peers. This study examined gestural production among school-aged children in a naturalistic context and how their gestures are semantically related to the accompanying…

Purpose: The current study investigated the effects of coaching as part of an emergent literacy professional development program to increase early childhood educators' use of verbal references to print and phonological awareness during interactions with children. Method: Thirty-one educators and 4 children from each of their classrooms (N = 121)…

Questioning and discussion techniques are effective instructional methods that develop critical thinking and problem solving skills. There is often inconsistent implementation of these techniques, which can result in a negative effect on student achievement. This case study explored elementary, middle, and high school teachers and evaluators'…

Objective: The onset of autism is usually conceptualized as occurring in one of two patterns, early onset or regressive. This study examined the number and shape of trajectories of symptom onset evident in coded home movies of children with autism and examined their correspondence with parent report of onset. Method: Four social-communicative…

Mathematics has a level of structure that transcends untutored intuition. What is the cognitive representation of abstract mathematical concepts that makes them meaningful? We consider this question in the context of the integers, which extend the natural numbers with zero and negative numbers. Participants made greater and lesser judgments of…

Based on Robinson's (2005) Cognition Hypothesis and Skehan and Foster's (2001) Limited Attentional Capacity Model, the current study attempted to investigate the effect of manipulating task complexity on argumentative writing quality in terms of lexical complexity, fluency, grammatical accuracy, and syntactic complexity. Task complexity was…

Bullying has become a nationwide concern at the K-12 level. Despite the target middle school's antibullying program, the incidence of bullying increased during the 1st and 3rd year of the program implementation. By identifying the perceptions of school personnel about this problem, district school leaders will be better equipped to select and…

The roles of linguistic, cognitive, and social-pragmatic processes in word learning are well established. If statistical mechanisms also contribute to word learning, they must interact with these processes; however, there exists little evidence for such mechanistic synergy. Adults use co-occurrence statistics to encode speech-object pairings with…
