Seven-and eight-year-old deaf children and hearing children of equivalent reading age were presented with a number of tasks designed to assess reading, spelling, productive vocabulary, speechreading, phonological awareness, short-term memory, and nonverbal intelligence. The two groups were compared for similarities and differences in the levels of…

The purpose of this study was to compare the effectiveness of the Raven's Standard Progressive Matrices, the Naglieri Nonverbal Abilities Test (NNAT), and the Iowa Test of Basic Skills (ITBS) in selecting for ethnically diverse students who may be gifted. The participants of the study were 175 students enrolled in Grades 3-5 and Grade 8 in a…

This study investigates the oral language skills of 8-year-old children with impaired reading comprehension. Despite fluent and accurate reading and normal nonverbal ability, these children are poor at understanding what they have read. Tasks tapping 3 domains of oral language, namely phonology, semantics, and morphosyntax, were administered,…

Correlations and mean score differences between IQs derived from the Universal Nonverbal Intelligence Test (UNIT; Bracken & McCallum, 1998) and the Wechsler Intelligence Scale for Children-Third Edition (WISC-III; Wechsler, 1991) were compared. Participants were Limited English Proficient (LEP) Mexican-American elementary school students, who…

Self-concept ratings of children with mathematics disabilities (MD), average mathematics achievement (AA), and high mathematics achievement (HA) who attended regular classes in grades 4 through 6 were compared. Twenty-four children in each group, who were selected from an original pool of 811 children, and who were matched one-to-one by grade,…

This paper describes the identification process of a Priority One Jacob K. Javits grant, Clustering Learners Unlocks Equity (Project CLUE), a university-school partnership. Project CLUE uses a "sift-down model" to cast the net widely as the talent pool of gifted second-grade students is formed. The model is based on standardized test scores, a…

This article examines students' ability to use the balance model to solve for unknowns. A teaching experiment was conducted in four Year 3 classrooms. This experiment focused on exploring the application of the balance model as an analogue for representing equations and solving for unknowns. The teaching experiment promoted a shift by students…

This study investigates whether working memory skills of children are related to teacher ratings of their progress towards learning goals at the time of school entry, at 4 or 5 years of age. A sample of 194 children was tested on measures of working memory, phonological awareness, and non-verbal ability, in addition to the school-based baseline…

Background: Five DNA markers (single-nucleotide polymorphisms, SNPs) have recently been found to be associated with general cognitive ability "g") in a sample of 7414 7-year-old twins. These children have also been studied at 2, 3, 4, and 7 years of age on measures of cognitive and language development and behaviour problems; family environment…
