This essay uses an enactive approach to map out the ways Ontario teachers, students, and parents have reimagined online mathematics education at the K-12 level during the COVID-19 pandemic. The essay highlights the importance of education researchers using an appropriate framework in understanding the emerging mathematics education realities. It…

Our research in statistical cognition uses both qualitative and quantitative methods. A mixed method approach makes our research more comprehensive, and provides us with new directions, unexpected insights, and alternative explanations for previously established concepts. In this paper, we review four statistical cognition studies that used mixed…

How do children learn math--and why do some children struggle with it? The answers are in "Number Sense and Number Nonsense," a straightforward, reader-friendly book for education professionals and an invaluable multidisciplinary resource for researchers. More than a first-ever research synthesis, this highly accessible book brings math…

Examines the role that memory plays in the understanding of mathematics. Areas discussed include: retention research; memory and teaching; structure and organization in memory; and transformations in memory. Relevant research and implications for instruction are addressed. (JN)

This monograph presents research findings from a series of 11 studies conducted in grades 5 through 10 on the role of games in learning mathematics. The first chapter considers "What is learning from a game?" and includes two examples of mathematical instructional games, with a definition of such games, cognitive effects, game-related…

Differences in cognitive structure are approached through consideration of cartesian and non-cartesian knowing. Figuration and configuration are described as two layers of cartesian knowing leading to the third layer, the cognitive structure. Knowing in general is then discussed, with comments on learning in another culture, Botswana. (MNS)

How the author moved from concern about research to development of prescriptive models of heuristic problem solving and the exploration of metacognition and belief systems is discussed. Student beliefs about problem solving, and their corollaries, are included. (MNS)

The conceptual difference between understanding and algorithmic performance is examined first. Then some dilemmas that flow from these distinctions are discussed. (MNS)

Fifty Brazilian children aged seven-13 were individually given addition and subtraction exercises. Counting was the preferred procedure, with use of school-taught algorithms limited. Some children decomposed numbers into tens and units and then worked at both levels. They rarely referred to previous results when doing related exercises. (MNS)

Twenty-nine students in grades four, six, and eight were asked to find solutions to fraction equivalence problems and to verify their solutions using discrete material. Discontinuities were observed between strategies students used for producing solutions and supporting knowledge grounded in physical reality. (Author/MNS)

The necessity for developing computational estimation procedures has resulted from an increased availability of calculators and microcomputers in the classroom. This article reports on a study of middle school students who were given computational problems to estimate and explain how answers were obtained. Results are discussed. (Author/DF)

This chapter from a longer work concerns the ability of children to solve arithmetic word problems. The studies reviewed suggest that, with age, children's improved ability to solve word problems primarily involves an increase in the complexity of conceptual knowledge required to understand the situations described in those problems. Considered in…

The mental activities involving functions were studied with 60 children aged 4-15. Search strategies used for solving a problem reveal different stages toward the discovery of the monotonic property, which correspond to stages of proportional reasoning found by Piaget. Dependence between stage and age is confirmed. (Author/MNS)

Included are a general introduction to the topic of metacognition, a discussion of how metacognition is involved in mathematical performance, and a short section on metacognition and instruction. (MNS)

This study examined the links students are able to make between formal expressions and situations to which they might refer. Students' understanding of a basic set of transformational rules in elementary algebra sign changes in addition and subtraction expressions with parentheses was assessed, exploring: (1) informal intuitive understanding of…
