This article characterizes the development of a deep and connected body of mathematical knowledge categorized by Ball and Bass' (2003b) model of Mathematical Knowledge for Teaching (MKT), as Specialized Content Knowledge for Teaching (SCK) in algebraic reasoning and number sense. The research employed multiple cases across three years from two…

Drawing on Geary's (1995) evolution-based model of cognitive and academic development, this study investigated the relation between biologically primary skills (vocabulary, executive functions, and visual-spatial processing) and subsequent word reading and calculation. It also examined the extent to which these relations were mediated by…

In this article, we draw on assemblage theory to investigate how children aged 5 engage with different material surfaces to explore ordinal and relational aspects of number. The children participate in an activity in which they first interact with a strip on the floor, then with a multi-touch iPad application, to work with numbers in expressive…

Education reform in early childhood education in China has often adopted western theories and pedagogies in efforts to facilitate educational change. The theory of multiple intelligences (MI) is an example of one adopted. This paper reports on a study that examined factors that influence Chinese kindergarten teachers' use of MI theory in their…

Multiraciality and mixed-race students have long been overlooked in K12 education discourse despite a significant increase in the number of students identifying as more than one race. Research that does address Multiracial students tends to focus on multiracial identity development of college students. However, educators and K12 school leaders…

What is the foundational knowledge that children rely on to provide meaning as they construct an exact symbolic number system? People and animals can quickly and accurately distinguish small exact quantities (i.e., 1 to 3). One possibility is that children's ability to map small quantities to spoken number words supports their developing exact…

Both recent evidence and research-based early mathematics curricula indicate that repeating patterns--predictable sequences that follow a rule--are a topic of major importance for mathematics development. The purpose of the current study was to help build a theory for how early repeating patterning knowledge contributes to early math development,…

Resilience can be a protective trait to promote mental health when implemented in the early years. This study explored the use of storytelling to foster children's learning of resilience. A pedagogically appropriate storybook was used to facilitate and embed the skills of resilience in children at primary school. Teachers (n = 2) and…

A long-standing debate in the field of numerical cognition concerns the degree to which symbolic and non-symbolic processing are related over the course of development. Of particular interest is the possibility that this link depends on the range of quantities in question. Behavioral and neuroimaging research with adults suggests that symbolic and…

The two prior studies that have examined associations between the sibling constellation and theory of mind in autism spectrum disorder yielded discrepant findings. Thus, efforts to better understand the sibling-theory of mind link in autism spectrum disorder are necessary. This study examined a sample of prekindergarten- and kindergarten-aged…

Baroody, Lai & Mix [2006. The development of young childrens number and operation sense and its implications for early childhood education. In B. Spodek, & O. N. Saracho (Eds.), "Handbook of research on the education of young children" (2nd Ed., pp. 187-221). NJ: Lawrence Erlbaum.] differentiate between four different learning…

In this study, we share our broad and deep search for what is known from blind-peer-reviewed research publications about the efficacy of the instructional practice of Number Talks. We describe our process for literature review and the subsequent analysis that revealed a shallow depth of articles for which one can discern the factors of quality of…

The number of English language learners (ELLs) in early childhood education (ECE) continues to increase, particularly with students whose first language (L1) is Spanish. Recent studies have shown the connection between teachers' self-efficacy and student achievement, but very few specifically address early childhood education teachers'…

Many states now mandate early screening for dyslexia, but vary in how they address these mandates. There is confusion about the nature of screening versus diagnostic assessments, risk versus diagnosis, concurrent versus predictive validity, and inattention to indices of classification accuracy as the basis for determining risk. To help define what…

Representations of numerical value have been assessed by using bounded (e.g., 0-1,000) and unbounded (e.g., 0-?) number-line tasks, with considerable debate regarding whether 1 or both tasks elicit unique cognitive strategies (e.g., addition or subtraction) and require unique cognitive models. To test this, we examined how well a mixed log-linear…
