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…

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…

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…

de Freitas, Elizabeth; Sinclair, Nathalie – Educational Studies in Mathematics, 2013
In this paper we study the mathematical body as an assemblage of human and non-human mathematical concepts. We argue that learners' bodies are always in the process of becoming assemblages of diverse and dynamic materialities. Following the work of the historian of science Karen Barad, we argue that mathematical concepts must be considered dynamic…

de Freitas, Elizabeth; Sinclair, Nathalie – Educational Studies in Mathematics, 2012
In this paper, we use the work of philosopher Gilles Chatelet to rethink the gesture/diagram relationship and to explore the ways mathematical agency is constituted through it. We argue for a fundamental philosophical shift to better conceptualize the relationship between gesture and diagram, and suggest that such an approach might open up new…

Sinclair, Nathalie; Watson, Anne; Zazkis, Rina; Mason, John – Journal of Mathematical Behavior, 2011
This paper elaborates the notion of a personal example space as the set of mathematical objects and construction techniques that a learner has access to as examples of a concept while working on a given task. This is different from the conventional space of examples that is represented by the worked examples and exercises in textbooks. We refer to…

Sinclair, Nathalie – For the Learning of Mathematics, 2001
The aesthetic dimension plays a central role in determining what mathematics proves personally and epistemologically relevant to children. Presents an example of a learning environment that attempts to explore this dimension and describes a small study that examined the responses of middle school students to this environment. (Contains 27…

Sinclair, Nathalie – For the Learning of Mathematics, 2002
Describes episodes from work with a small group of 8th grade students who were working independently on a geometry course. Uses Geometer's Sketchpad for the tasks. Discusses students' reasoning skills and their interpretation of the painting in terms of the mathematical properties and relationships. (KHR)

Colgan, Lynda; Higginson, William; Sinclair, Nathalie – Alberta Journal of Educational Research, 1999
Describes an ongoing study in which 60 beginning elementary teachers have access to an online community that integrates many Internet communication tools. The study seeks to identify specific determinants of successful use of computer technology as professional development and collaborative learning tools and to describe the interaction between…
