Adolescents' (n = 342, 169 boys) general algebra and algebra word problems performance were assessed in 9th grade as were intelligence, academic achievement, working memory, and spatial abilities in prior grades. The adolescents reported on their academic attitudes and anxiety and their teachers reported on their in-class attentive behavior in 7th…

Children's first mathematics concept is their understanding of the quantities represented by number words (cardinal value), and the age at which they achieve this insight predicts their readiness for mathematics learning in school. We provide the first exploration of the factors that influence the age of becoming a cardinal principle knower (CPK),…

Purpose: Many children begin school with limited vocabularies, placing them at a high risk of academic difficulties. The goal of this study was to examine the effects of a vocabulary intervention program, "Story Friends," designed to improve vocabulary knowledge of at-risk preschool children. Method: Twenty-four early-childhood…

Recent advances in understanding visual working memory, the limited information held in mind for use in ongoing processing, are extended here to examine auditory working memory development. Research with arrays of visual objects has shown how to distinguish the capacity, in terms of the "number" of objects retained, from the…

Purpose: Many children begin school with limited vocabularies, placing them at a high risk of academic difficulties. The goal of this study was to examine the effects of a vocabulary intervention program, Story Friends, designed to improve vocabulary knowledge of at-risk preschool children. Method: Twenty-four early-childhood classrooms were…

Purpose: The purpose of this study was to examine cognitive flexibility for semantic and perceptual information in preschool children who stutter (CWS) and who do not stutter (CWNS). Method: Participants were 44 CWS and 44 CWNS between the ages of 3;0 and 5;11 (years;months). Cognitive flexibility was measured using semantic and perceptual…

Sex differences in the strength of the relations between mathematics anxiety, mathematics attitudes, and mathematics achievement were assessed concurrently in sixth grade (n = 1,091, 545 boys) and longitudinally from sixth to seventh grade (n = 190, 97 boys). Mathematics anxiety was composed of two facets, one associated with evaluations and the…

The researchers investigated the effects of adult language input on the quantity of language, vocabulary development, and understanding of basic concepts of deaf and hard of hearing (DHH) children who used listening and spoken language. Using audio recording and Language ENvironment Analysis (LENA) software, the study involved 30 preschool DHH…

At the beginning of preschool (M = 46 months of age), 197 (94 boys) children were administered tasks that assessed a suite of nonsymbolic and symbolic quantitative competencies as well as their executive functions, verbal and nonverbal intelligence, preliteracy skills, and their parents' education level. The children's mathematics achievement was…

Most vocabulary growth during the school-age years occurs incidentally. However, little is understood about the influence of language skills on word knowledge growth during reading. Using a pretest-posttest quasi-experimental design, we examined incidental word learning through reading, considering the presence/absence of supportive context and…

Care Quality Rating and Improvement Systems (QRISs) have advanced and matured, a number of states and localities have undertaken evaluations to validate the systems. Such efforts stem from the desire to ensure that the system is designed and operating in the ways envisioned when the system was established. Given that a central component in a QRIS…
