Sinclair, Nathalie; Ferrara, Francesca – For the Learning of Mathematics, 2021
In this article, we explore Whitehead's claim that experience is fundamentally affective. We do so in the context of an Italian primary school classroom featuring the use of the multitouch application "TouchCounts." We study the way in which the children and the iPad take each other up and the meanings of number and arithmetic that…

Sinclair, Nathalie; Chorney, Sean; Günes, Canan; Bakos, Sandy – ZDM: Mathematics Education, 2020
Many studies have documented the challenges facing teachers who use digital technologies in their classrooms. This is especially true for digital technologies that offer new models or representations of school mathematics concepts. In this article, we report on a collaboration between teachers and researchers around the use of a novel touchscreen…

Baccaglini-Frank, Anna; Carotenuto, Gemma; Sinclair, Nathalie – ZDM: The International Journal on Mathematics Education, 2020
Research has highlighted the potential of digital technology to support the development of children's number sense abilities. However, the main focus of such research has been on apps affording directed interactions, where only one solution strategy is available, and it has targeted mostly cardinality. Little is known, in these terms, about task…

Bruce, Catherine D.; Davis, Brent; Sinclair, Nathalie; McGarvey, Lynn; Hallowell, David; Drefs, Michelle; Francis, Krista; Hawes, Zachary; Moss, Joan; Mulligan, Joanne; Okamoto, Yukari; Whiteley, Walter; Woolcott, Geoff – Educational Studies in Mathematics, 2017
This paper finds its origins in a multidisciplinary research group's efforts to assemble a review of research in order to better appreciate how "spatial reasoning" is understood and investigated across academic disciplines. We first collaborated to create a historical map of the development of spatial reasoning across key disciplines…

Francis, Krista; Bruce, Cathy; Davis, Brent; Drefs, Michelle; Hallowell, David; Hawes, Zachary; McGarvey, Lynn; Moss, Joan; Mulligan, Joanne; Okamoto, Yukari; Sinclair, Nathalie; Whiteley, Walter; Woolcott, Geoff – Canadian Journal of Science, Mathematics and Technology Education, 2017
Spatial reasoning plays a vital role in choice of and success in science, technology, engineering, and mathematics (STEM) careers, yet the topic is scarce in grade school curricula. We conjecture that this absence may be due to limited knowledge of how spatial reasoning is discussed and engaged across STEM professions. This study aimed to address…

Coles, Alf; Sinclair, Nathalie – For the Learning of Mathematics, 2017
In this article, we question what is an appropriate balance of ordinal and cardinal work in the early learning of number. We see an over-emphasis, in current research and practice, on the cardinal that leads, for example, to only using small numbers. We report on empirical work we have carried out in the UK and Canada that suggests the potential…

Sinclair, Nathalie; Bartolini Bussi, Maria G.; de Villiers, Michael; Jones, Keith; Kortenkamp, Ulrich; Leung, Allen; Owens, Kay – ZDM: The International Journal on Mathematics Education, 2016
This survey on the theme of Geometry Education (including new technologies) focuses chiefly on the time span since 2008. Based on our review of the research literature published during this time span (in refereed journal articles, conference proceedings and edited books), we have jointly identified seven major threads of contributions that span…

Ferrara, Francesca; Sinclair, Nathalie – Educational Studies in Mathematics, 2016
This paper focuses on pattern generalisation as a way to introduce young students to early algebra. We build on research on patterning activities that feature, in their work with algebraic thinking, both looking for sameness recursively in a pattern (especially figural patterns, but also numerical ones) and conjecturing about function-based…

Sinclair, Nathalie; Chorney, Sean; Rodney, Sheree – Mathematics Education Research Journal, 2016
In this paper, we investigate the mathematical, social and affective nature of children's engagement with "TouchCounts," a multitouch application for counting and doing arithmetic. In order to study these dimensions of engagement in a way that recognizes their fundamental intertwinement, we use rhythm as a primary unit of analysis.…

Rodney, Sheree; Rouleau, Annette; Sinclair, Nathalie – Canadian Journal of Science, Mathematics and Technology Education, 2016
Public perception about mathematics education is developed and sustained by the Canadian news media. Our goal is to understand better the nature of this public discourse by identifying what is being communicated and how it is presented. We examine a data corpus of 71 online national newspaper articles (published between 2013 and 2015, a period…

Ng, Oi-Lam; Sinclair, Nathalie – ZDM: The International Journal on Mathematics Education, 2015
In this paper, we investigate children's learning of reflectional symmetry in a dynamic geometry environment. Through a classroom-based intervention involving two 1-h lessons, we analyse the changes in the children's thinking about reflectional symmetry: first, they developed dynamic and embodied ways of thinking about symmetry after working with…

Ng, Oi-Lam; Sinclair, Nathalie – Canadian Journal of Science, Mathematics and Technology Education, 2015
In this article, we report on two lessons aimed at introducing junior high school students to the idea of shearing in a touchscreen dynamic geometry environment. By using shearing, we hoped to shift students' attention away from a formula-driven, computational conception of area toward a more geometric one. We found that the students were able to…

Sinclair, Nathalie; Pimm, David – North American Chapter of the International Group for the Psychology of Mathematics Education, 2014
In this paper, we explore a richer sense of finger gnosis with respect to three- and four year-olds' interactions with a novel iPad application ("TouchCounts"), focusing on their responses to an "inverse subitising" task. The direct and tactile nature of their engagement with "TouchCounts" leads to a striking shift…

Kaur, Harpreet; Sinclair, Nathalie – North American Chapter of the International Group for the Psychology of Mathematics Education, 2014
This paper presents preliminary results of longitudinal study on the development of children's geometric thinking in dynamic geometry environments. Here we investigate young children's (age 7-8, grade 2/3) interactions, in a whole classroom setting with an Interactive Whiteboard, with Sketchpad-based tasks involving the use of different types of…

Gol Tabaghi, Shiva; Sinclair, Nathalie – Technology, Knowledge and Learning, 2013
This article analyses students' thinking as they interacted with a dynamic geometric sketch designed to explore eigenvectors and eigenvalues. We draw on the theory of instrumental genesis and, in particular, attend to the different dragging modalities used by the students throughout their explorations. Given the kinaesthetic and dynamic…
