Behaviour problems in early childhood have a lasting impact on cognitive development and education attainment in later adolescence and into adulthood. Here we address the relationship conduct and hyperactivity problems at school entrance, and vocabulary acquisition in adolescence. We compare performance in identical assessments across two…

Understanding science allows students with and without developmental and behavioral-based (DB) disabilities to better appreciate the world around them as well as prepare them for the growing science-related job market. However, students in the United States consistently underperform on science achievement tests compared to students from other…

This study investigates associations between trajectories of children's vocabulary development and subsequent behavioral and emotional difficulties via two potential mediating mechanisms; literacy and peer problems. Nationally representative data from 4,983 Australian children were used to examine trajectories of receptive vocabulary (4-5, 6-7,…

Potential bidirectional associations between preschool classroom overactive (or externalizing) and underactive (or internalizing) behaviors and language and literacy skills (i.e., vocabulary and listening comprehension) were examined in a sample of children enrolled in Head Start (N = 297). Cross-lagged panel designs using structural equation…

The purpose of this study is to examine the bidirectional relationship between children's language development and challenging behaviors as well as the moderating roles of gender and race/ethnicity. We conducted a number of structural equation modeling analyses with a national representative sample (N = 2,462) of Head Start children from the 2014…

The number of foreign languages spoken in Germany is rising, and as a result German is increasingly being learned as a second language (L2). This is a challenge for many secondary-school students, especially those who have learning disabilities (LD) and behavioral difficulties, which are often accompanied by reduced motivation to learn, in this…

Students with learning and behavioral problems often face enormous barriers to successful school performance. When the language of instruction is not the students' first language and they are already in secondary school, this is compounded by additional challenges, especially with regard to vocabulary and reading -- subjects that are fundamental…

Background: The present study aimed at investigating mother-child dyadic co-regulation patterns in dyads with children with intellectual disability (ID). Method: 24 children paired for developmental age and vocabulary size (8 with chromosome 14 aberrations, 8 with Down syndrome, and 8 with typical development) and their mothers participated in the…

The purpose of this study was to examine the efficacy of the Children's School Success (CSS) curriculum for 4-year-old children enrolled in preschool programs designed to prepare them for success in their early public school grades. The study took place in preschool classes located in five regionally distributed states, all of which were inclusive…

Objectives: The effects of iPod-based visual activity schedules with embedded video models (video-enhanced activity schedules) on the academic skills and challenging behavior of children with autism spectrum disorder (ASD) were evaluated. Methods: A multiple baseline design across three target skills was used with two participants, ages 9 and 11,…

This classroom discourse study examines how curriculum becomes a resource for identity performance in one ESL classroom. Conceptualizing identity as performance, I adopt a small stories approach to analyze how one routinized vocabulary instructional activity was appropriated by classroom participants to perform identities and construct the…

This study examined the relations between problem behaviors and early learning outcomes among 138 children in dual-language pre-K programs who were identified at the beginning of the school year to be at risk for difficulties in early language and literacy development. Children's expressive and receptive vocabulary, listening comprehension, and…

Difficulties in peer acceptance during elementary school have been associated with emotional and behavioural problems. This study used a randomized controlled intervention design to test whether improvements in peer acceptance mediated reduced rates of emotional and behavioural problems in intervention compared to control-group children. A total…

Purpose: The authors tested associations between (a) parent-reported temporary vs. persistent vocabulary delay and (b) parent-reported behavioral/emotional problems in a sample of 5,497 young Dutch children participating in a prospective population-based study. Method: Mothers completed the MacArthur Communicative Development…
