Background: The study was conducted in an attempt to further our understanding of how working memory contributes to written arithmetical skills in children. Aim: The aim was to pinpoint the contribution of different central executive functions and to examine the contribution of the two subcomponents of children's written arithmetical skills.…

It was the perfect Halloween project. Each class would construct a three-dimensional "monster" out of common classroom materials (construction paper, cardboard boxes, tape, markers, glue, string, etc.), then write down instructions for building the monster and send them off to another class in the district, or in some other district, or even some…

Students in undergraduate chemistry courses find, as a rule, topics with a strong mathematical basis difficult to master. In this study we investigate whether such mathematically related problems are due to deficiencies in their mathematics foundation or due to the complexity introduced by transfer of mathematics to a new scientific domain. In the…

Throughout much of the world, boys continue to outscore girls on standardized mathematics tests. For example, in most of the 57 countries that participated in the Programme for International Student Assessment (PISA) 2006, boys' performance was significantly higher than girls on the mathematics scale. This fact alone can harm girls' opportunities…

In California, Algebra I is the 8th grade math content standard. The United States Department of Education found the annual 8th grade General Math California Standards Test to be out of compliance with the federal No Child Left Behind Act of 2001 since it assesses 6th and 7th grade math standards and not Algebra I math content. In response to the…

This most recent Iowa Kids Count data book, "Iowa Kids Count 2010: Trends in the Well-Being of Iowa Children," provides data on 20 different indicators of child and family well-being at the United States, Iowa, substate and county level. The annually produced data book presents health, education, welfare and economic data including…

What is the nature of the association between age (7-11 years) and performance on mathematical equivalence problems (e.g., 7 + 4 + 5 + 7 + _)? Many prevailing theories suggest that there should be a positive association. However, change-resistance accounts (e.g., N. M. McNeil & M. W. Alibali, 2005b) predict a U-shaped association. The purpose of…

How accurate are self-estimates of cognitive abilities? An investigation of self-estimates of verbal, math, and spatial abilities is reported with a battery of parallel objective tests of abilities. Self-estimates were obtained prior to and after objective ability testing (without test feedback) in order to examine whether self-estimates change…

This study examined longitudinal predictive relationships between young children's classroom behaviors and their growth in mathematics skills during the primary grades. Using the Early Childhood Longitudinal Study--Kindergarten cohort, the authors tested a longitudinal model featuring positive (interpersonal skills and approaches to learning) and…

This paper provides an instrumental account of precalculus students' graphical process for solving polynomial inequalities. It is carried out in terms of the students' instrumental schemes as mediated by handheld graphing calculators and in cooperation with their classmates in a classroom setting. The ethnographic narrative relays an instrumental…

This research aims at identifying the precursors of mathematics learning at the beginning of primary school. There are few experimental studies on this topic and existing ones use between-subjects designs and correlation analysis. This paper analyses longitudinal data to investigate whether the relationship between basic abilities and mathematics…

The aim of the present study was investigate the relationship between working memory and reading and mathematical skills in 55 children diagnosed with developmental coordination disorder (DCD). The findings indicate a pervasive memory deficit in all memory measures. In particular, deficits observed in visuospatial short-term and working memory…

This article focuses on the Problem-Solving Cycle (PSC), a model of professional development designed to assist teachers in supporting their students' mathematical reasoning. Each PSC is a series of three interrelated workshops in which teachers share a common mathematical and pedagogical experience, organized around a rich mathematical task.…

This article describes recommendations made by participants in a large project of the Mathematical Association of America (MAA), in which representatives of "partner disciplines" shared what they would like students to learn in the first two years of college mathematics. The article further suggests implications for high school mathematics.…

How learning about learning trajectories has helped a teacher develop goals and objectives for her preschool children's mathematical knowledge, identify children's developmental levels in specific mathematical topics, and chart paths for instruction that will guide their learning of mathematics. Participating in research encouraged her to develop…
