Understanding numerical magnitude is critical to the development of mathematics proficiency, and math interventions targeting magnitude knowledge have been shown to improve outcomes for students with math learning difficulties across grade levels. While recent studies have found that growth in magnitude knowledge mediates fractions intervention…

This study uses Program for the International Assessment of Adult Competencies (PIAAC) data to examine latent profiles of engagement in reading, numeracy, writing, and computer skills-use for U.S. adults with low literacy skills. Additionally, we examine how these profiles relate to overall literacy performance and demographic heterogeneity.…

Rational numbers (i.e., fractions, percentages, decimals, and whole-number frequencies) are notoriously difficult mathematical constructs. Yet correctly interpreting rational numbers is imperative for understanding health statistics, such as gauging the likelihood of side effects from a medication. Several pernicious biases affect health…

Early numeracy skills are vital for kindergarten students because they provide the foundation for acquiring mathematics skills in both kindergarten and subsequent years. Teacher support to intervene on kindergarteners at-risk for poor mathematics learning outcomes is a promising approach to address this achievement gap. The current study…

This study examined the effects of training involving spatial versus nonspatial representations of numerical magnitude for promoting arithmetic fluency. The key goal was to advance theoretical understanding of the relation between spatial and math learning, while simultaneously laying the groundwork for the development of future educational…

This study investigated whether transitory and persistent poverty spells were associated with children's learning (literacy and numeracy scores) and executive function outcomes in Ghana. Children resided in the Greater Accra region (N = 2,154; 49% female; M[subscript age] = 5.2 years at wave-1) and were followed at four-time points over three…

Children vary widely in their number knowledge by the time they enter kindergarten, and this variation is related to their future academic success. Although talk about number predicts children's early understanding of foundational number concepts, we know little about whether interventions can increase this talk nor about the types of number talk…

Comparing health risks that include ratios of integers (e.g., 12 in 1,000) is challenging. We tested whether a worked-example intervention with number-line visual displays improved adults' risk-comparison accuracy, whether pretest confidence moderated learning, and which individual differences related to accuracy. Replicating prior work, U.S.…

Volunteering, STEM education and occupation, and information-processing skills such as literacy, numeracy, and digital problem-solving skills are important indicators of a nation's well-being as they represent civic engagement, economic development, and the human capital of the population. Although these critical social indicators have been…

Effective classroom management is critical to supporting student learning and success in school. However, little research has focused specifically on the impact of classroom management on student mathematics achievement, especially in the early elementary grades or in a small group (i.e., Tier 2) context. To address this need we investigated the…

Chinese children routinely outperform American peers in standardized tests of mathematics knowledge. To examine mediators of this effect, 95 Chinese and US 5-year-olds completed a test of overall symbolic arithmetic, an IQ subtest, and three tests each of symbolic and non-symbolic numerical magnitude knowledge (magnitude comparison, approximate…

Latino parents support children's academic skills through their involvement in daily living activities. Prior work has focused on conventional literacy (e.g., book reading) and numeracy activities (e.g., teaching numbers). Less-visible home activities that are high-priority, high-value cultural practices in Latino communities are food sharing…

Classroom-level quality measures are widely used in early education settings but may mask important variation in learning experiences across children in the same classroom. This study investigates this possibility using detailed data from an observational measure of individual children's learning experiences--Individualizing Student Instruction…

Across geographically diverse samples, engagement in stimulating activities with young children is considered an important element of parenting that promotes cognitive, behavioral, and social-emotional development. Indicators of stimulation activities are often summed, based on the assumption that more stimulation is better and that different…

This qualitative study explored the views of community college employers, faculty, administrators, and students on the importance of foundational skills, including literacy, numeracy, and problem-solving skills, in science, technology, engineering, and math (STEM) programs of study. Participants (N=50) were recruited, semi-structured interviews…
