This study hypothesized that HISD prekindergarten participation consistently correlated with better educational outcomes for students. Taking into account students' age differences through kindergarten enrollment, propensity score matching controlled for students' background characteristics. Three cohorts of students in this study were eligible or…

The Australian Council for Educational Research (ACER) is one of the world's leading educational research centres. ACER's mission is to create and promote research-based knowledge, products and services that can be used to improve learning across the life span. This annual report describes ACER's milestones and accomplishments for the 2016-2017…

This study describes children's early math skills and the kindergarten mathematics content to which they are exposed. The authors focus specifically on teacher survey responses to items about content coverage that align most closely with the content covered on the ECLS-K kindergarten mathematics achievement test. They examine the influence…

In the present study, the authors developed and tested a purposeful eight-week number sense intervention for kindergartners from low-income families. Participants were recruited from kindergarten classes in five schools. Building on other investigations (e.g., Baroody et al., 2009; Chard et al., 2008; Ramani & Siegler, 2008), the present…

The aim of this study was to examine whether there are gender differences in mathematics achievement and in beliefs about mathematics of preservice teachers over a period of four years. Data were collected from preservice teachers (156 males and 155 females) from the Adiyaman University Faculty of Education in Turkey. The Mathematics as a Gendered…

Using five waves of panel data from 8,008 children in the ECLS-K, the current study compared children's academic performance growth curves from kindergarten through fifth grade among three types of nondisrupted and three types of disrupted families. The analyses found that children in nondisrupted two-biological-parent and nondisrupted stepparent…

What predicts human mathematical competence? While detailed models of number representation in the brain have been developed, it remains to be seen exactly how basic number representations link to higher math abilities. We propose that representation of ordinal associations between numerical symbols is one important factor that underpins this…

In this article, we present the results from a longitudinal examination of the impact of a "Standards"-based or reform mathematics curriculum (called CMP) and traditional mathematics curricula (called non-CMP) on students' learning of algebra using various outcome measures. Findings include the following: (1) students did not sacrifice…

Previous research has illuminated an important connection between stereotypes and the performance of those targeted by a stereotype. This body of work suggests that even implicit (i.e., nonconscious and unintended) math-gender stereotyping is related to poor math performance among women. Our longitudinal study sought to measure students'…

This study evaluated the interrelations among cognitive precursors across quantitative, linguistic, and spatial attention domains that have been implicated for math achievement in young children. The dimensionality of the quantity precursors was evaluated in 286 kindergarteners via latent variable techniques, and the contribution of precursors…

This study aims at enhancing math learning and general self-regulation by supporting daily self-regulated learning during math homework. The authors use standardized diaries as a self-monitoring tool to support self-regulatory behaviour. Following the theory of self-monitoring, frequent self-monitoring of self-regulation will lead to an…

This article examines the effects of one year of exposure to "Learning to Read in a Healing Classroom" (LRHC) on the reading and math skills of second- to fourth-grade children in the low-income and conflict-affected Democratic Republic of the Congo. LRHC consists of two primary components: teacher resource materials that infuse…

In this study, we investigated gender and minority achievement gaps on 8th-grade science items employing a multilevel item response methodology. Both gaps were wider on physics and earth science items than on biology and chemistry items. Larger gender gaps were found on items with specific topics favoring male students than other items, for…

This qualitative study was conducted to identify the potential of using iPad as a supplement to teach math to students with learning disabilities. Ten teacher candidates from a university in the south provided one-on-one math tutoring services to ten students in a self-contained classroom at a local high poverty elementary school. The students…

Learning algebra is difficult for many students in part because of an emphasis on the memorization of abstract rules. Algebraic reasoners across expertise levels often rely on perceptual-motor strategies to make these rules meaningful and memorable. However, in many cases, rules are provided as patterns to be memorized verbally, with little overt…
