The frequent misinterpretation of the nature of confidence intervals by students has been well documented. This article examines the problem as an aspect of the learning of mathematical definitions and considers the tension between parroting mathematically rigorous, but essentially uninternalized, statements on the one hand and expressing…

Research demonstrates how enjoyable and meaningful learning is for children when there is smooth transition between home and classroom. This autoethnographic research used in-depth interviews and observations to examine the Ethiopian people's spiritual centered lifestyle at home and whether this style is carried into science classes in the…

In this article, we outline the findings of a Canadian survey study (N = 302) that focused on the extent of computer algebra systems (CAS)-based technology use in postsecondary mathematics instruction. Results suggest that a considerable number of Canadian mathematicians use CAS in research and teaching. CAS use in research was found to be the…

This article investigates some of the specific features involved in accommodating the idea of actual infinity as it appears in set theory. It focuses on the conceptions of two individuals with sophisticated mathematics background, as manifested in their engagement with variations of a well-known paradox: the ping-pong ball conundrum. The APOS…

In this article we explore the mechanisms through which one group of preservice teachers engage in "Collective Property Noticing"--a phenomenon in which group members integrate individual contributions such that the group, as a unit, notices mathematical properties of their collective image. Drawing on improvisational theory to help to…

Minority Francophone students in predominantly English-speaking Canadian provinces tend to perform lower on large-scale assessments of achievement than their Anglophone peers and majority Francophone students in Quebec. This study is the first to apply multilevel modeling methods to examine the extent to which school-level factors may be…

I have developed an adaptation of the emerging duoethnography methodology that allows me to draw on my processes of creating mathematics, interpret these processes for what they might mean for classrooms, and explore/reconceptualize my complementary and competing perspectives as a mathematician and an educator. This article includes a…

Situated theories of learning recognize the rules, tools, goals, and communities within which activities develop. Similarly, situated theories of epistemic cognition recognize that individuals' ideas about knowledge are tentative and dependent on particular contexts. In this study, we bring these frameworks together and qualitatively examine…

I argue that larger cultural concerns about human-technology interactions are seldom addressed in teacher education. This article seeks to trace cultural anxieties about technology by addressing the long-standing trope of human versus machine; examine how these concerns are manifested and addressed (or not) in popular culture, educational…

Within Canadian science classrooms, Indigenous ways-of-knowing and ways-of-being continue to be underrepresented and undervalued. For Indigenous students, this often results in negative experiences and disparate achievement rates when compared to their non-Indigenous classmates. Recent decolonizing science education literature suggests critical…

The complementary use of the theories of instrumental genesis and shifts of attention enabled me to obtain insights into students' understandings of the concepts of eigenvector and eigenvalue. My analysis suggests that the use of different dragging modalities can provide evidence of shifts in structure of a student's attention and…

The author compares two frameworks, one proposed by Sauvé (2005) for environmental education (EE) and the other prepared by Pedretti and Nazir (2011) for Science, Technology, Society and Environment (STSE) education. With the aim of investigating the utility of the two frameworks as tools for analysis of science teaching practice, the author…

Science education research has built a strong body of work on students' understandings but largely overlooked the nature of science knowledge itself. Legitimation Code Theory (LCT), a rapidly growing approach to education, offers a way of analyzing the organizing principles of knowledge practices and their effects on science education. This…

The rapid diversification of communities in Ontario has necessitated the provincial government to reevaluate public school curriculums and policies to make schools more inclusive and reflective of its diverse population. This article critically analyzes the content of the latest revised science curricula for Grades 1 to 10 and assesses the degree…

This article offers explanations as to why good candidates for mathematics or physics degrees might opt to study subjects other than STEM (science, technology, engineering, mathematics) subjects at university. Results come from analysis, informed by psychoanalytic theory and practice, of narrative-style interviews conducted with first-year…
