The Home Learning Environment (HLE) focuses on everyday learning habits in families to support children's competency development. In this study, we used multitrait-multimethod (MTMM) analyses to compare two theoretical dimensions and three methods for assessing the HLE and their associations with linguistic and mathematical competencies of…

In this article, we analyze symbolic and non-symbolic numerical abilities of parents in order to understand whether these are predictors of children's numerical skills, considering basic symbolic, non-symbolic, and formal math skills (i.e., written calculation). A battery of cognitive and math tasks was administered to a sample of 83 children with…

Well-designed mathematics instruction focused on concepts and problem-solving skills associated with measurement and data analysis can build a foundational understanding for more advanced mathematics. This study investigated the efficacy of the Precision Mathematics Level 1 (PM-L1) intervention, a Tier 2 print- and technology-based mathematics…

In an effort to promote best practices regarding mathematics teaching and learning at the preschool level, national advisory panels and organizations have emphasized the importance of children's emergent counting and related competencies, such as the ability to verbally count, maintain one-to-one correspondence, count with cardinality, subitize,…

For learning math, non-symbolic quantity skills, symbolic skills and the mapping between number symbols and non-symbolic quantities are all important precursors. Little is known, however, about the interrelated development of these skills. The current study focuses on numerical development by: (a) investigating the structure of non-symbolic,…

Rapid automatized naming (RAN) is widely used to identify reading disabilities (RD) and has recently been considered a potential predictor of risk for mathematics learning disabilities (MLD). Here we longitudinally examine RAN performance from Grades K to 8, to view how growth on RAN response time differs for children with RD versus MLD. Across…

Early numeracy in kindergarten has proven to be a strong predictor of mathematical achievement. The aims of this study were to test the effectiveness of a remedial numeracy program for children who were low performing and to evaluate the role of visual and verbal working memory in the development of numeracy. The study included 196 kindergartners.…

The training requirements of foreign-born workers may be different from those of native-born workers in similar jobs. Over recent decades Australian immigration policy has focused predominantly on accepting high-skilled migrants. Although this focus has resulted in the successful integration of foreign-born workers into the Australian labour…

The 2003 National Assessment of Adult Literacy (NAAL) assessed the English literacy skills of a nationally representative sample of more than 19,000 U.S. adults (age 16 and older) residing in households and correctional institutions. NAAL is the first national assessment of adult literacy since the 1992 National Adult Literacy Survey (NALS). The…

Understanding of the cardinality principle in children with Williams Syndrome (WS) was compared to that of typically developing children. Findings indicated that such understanding was extremely delayed in WS children and only at the level predicted by their visuo-spatial mental age. Findings suggested that visuo-spatial ability played a greater…
