Research Findings: The present study examined the amount of exposure to math activities that children of low socioeconomic status (SES) encounter in private community-based preschool classrooms and whether greater time in these activities predicted higher math skills. Three cohorts of 4- to 5-year-old children were recruited from 30 private…

Equitable assessment of students' mathematical thinking is imperative for effective instruction. This two-part study investigated teachers' judgement of students' mathematical thinking. In Study One, we used a national data set to determine the correlation between teachers' judgement of students' mathematical thinking and scores from a…

This investigation considered the short-term benefits of early childhood education participation at age 3 for 1,213 children from low-income families living in a large and linguistically diverse county. Although no benefits emerged for executive functioning, children who participated in formal early childhood programs at the age of 3 entered…

This investigation considered the short-term benefits of early childhood education participation at age 3 for 1,213 children from low-income families living in a large and linguistically diverse county. Although no benefits emerged for executive functioning, children who participated in formal early childhood programs at the age of 3 entered pre-K…

Relationships between attention/executive functions and language learning were investigated in students in Grades 4 to 9 (N = 88) with and without specific learning disabilities (SLDs) in multiword syntax in oral and written language (OWL LD), word reading and spelling (dyslexia), and subword letter writing (dysgraphia). Prior…

The present study examined the psychometric properties of scores from a direct measure of behavioral regulation, the Head-Toes-Knees-Shoulders task (HTKS) with 3- to 6-year-old children in the United States, Taiwan, South Korea, and China. Specifically, we investigated (a) the nature and variability of HTKS scores, including relations to…

The present study examined whether multiple opportunities to learn math were associated with smaller socioeconomic status (SES) disparities in fifth-grade math achievement using data from the NICHD Study of Early Child Care and Youth Development (SECCYD; N = 1,364). High amounts of procedural math instruction were associated with higher…

This study examined the performance of 48 students (mean age 10 years, 6 months) referred for evaluation of learning disabilities with the Wechsler Individual Achievement Test (WIAT) and the Woodcock-Johnson Psychoeducational Battery-Revised Tests of Achievement (WJ-R). The student sample consisted of 33 males and 15 females, all attended schools…

This nonexperimental, longitudinal field study examines the extent to which variation in observed classroom supports (quality of emotional and instructional interactions and amount of exposure to literacy and math activities) predicts trajectories of achievement in reading and math from 54 months to fifth grade. Growth mixture modeling detected…
