Expecting teachers to support their students in making mathematical connections is an unreasonable request when teachers themselves have not had opportunities to connect their own understandings. This study investigates how prospective elementary teachers can deepen their mathematical understanding using recommendations developed by mathematics…

In this commentary, we explore tensions between engaging students in authentic disciplinary mathematical activity and insights from critical theorists who analyze equity in mathematics education. The tensions arise as engaging students in authentic mathematical activity usually involve having students adopt the language and norms of another…

Gestures play a role in perception, production, and comprehension of language and have been shown to differ cross-linguistically and cross-culturally in aspects of performance and form-meaning relationships. Furthermore, gestures can serve as analytical tools to access tacit embodied-imagistic mathematical meanings that add to verbal-linguistic…

Little is available in mathematics education research about what the teacher can anticipate from the students when applying inquiry-based learning (IBL). Even less is known about how to recognize and exploit on the spot when a mathematical domain, other than the one in focus, is activated in the students' minds. Yet, in tests, in everyday life,…

In this paper, we explore beliefs about teaching and learning held by 27 Namibian 11th graders (ages 16 to 18) experiencing difficulties in learning mathematics. Namibia's education system and its people's access to mathematics has suffered throughout years of colonization and apartheid. Namibia has made significant strides to create access and…

The "Canadian Journal of Science, Mathematics and Technology Education (CJSMTE)" is celebrating its 20 years in 2020. This paper compares the data from the 2009 review (Wallace, 2009) and the 2015 review (Wiseman & Pegg, 2015) to the data from the past 20 years, from 2001 to 2020. The findings suggest that there was an increase in…

The "Canadian Journal of Science, Mathematics and Technology Education" ("CJSMTE") is celebrating its 20 years in 2020. This paper compares the data from the 2009 review (Wallace, 2009) and the 2015 review (Wiseman & Pegg, 2015) to the data from the past 20 years, from 2001 to 2020. The findings suggest that there was an…

Taking as its point of departure, situations arising in classrooms exposed to a heavy use of CAS, exemplified by the Danish upper secondary school mathematics program, the paper discusses the use of "old" cognitive frameworks of mathematics education as an alternative to more recent theoretical developments in the field. The paper draws…

The 20th anniversary of this journal finds us at a crossroads in many ways. Mathematics education itself has always existed at an unclear intersection of mathematics and education. As well, in mathematics education, the poles of reform and traditional learning can pull the community apart. And now, in the world, we find ourselves at a crossroads…

In preparing this essay in celebration of 20 years of the "Canadian Journal of Science, Mathematics and Technology Education (CJSMTE)," the author reflects on her developmental trajectory as a science teacher educator, and researcher through the lens of professional learning. She describes how her engagement with the journal contributed…

The increasing concern in North America regarding the workforce's ability to maintain a competitive position in the global economy has led to an increased interest in effective science, technology, engineering, and mathematics (STEM) education. The purpose of this study was to investigate the effect of engaging in STEM project-based learning (PBL)…

Acknowledging the contribution of mathematicians to the mathematical education of teachers, we explore mathematicians' perspective on an envisioned Calculus course for prospective teachers. We analyzed semi-structured interviews with 24 mathematicians using the EDW (Essence-Doing-Worth) framework (Hoffmann & Even, 2018, 2019); and…

In this article, we examine non-Indigenous pre-service teachers' (PSTs) storylines in terms of how they conceive the call to incorporate First Peoples' worldviews and perspectives into their mathematics teaching, a current/recent mandate of the province of British Columbia. In an undergraduate teacher preparation course, discussions of how…

As its title suggests, this commentary utilizes the 20th year of publication of the "Canadian Journal of Science, Mathematics, and Technology Education" as an opportunity for me, the current English language mathematics education editor, to confess. I confess to imposter syndrome and editorial naiveté. I confess to evolving from putting…

This year (2020), when the "Canadian Journal of Science, Mathematics, and Technology Education" (CJSMTE) is turning 20, I am completing my 40th year in the field of science, mathematics, and technology education, initially teaching the school subjects and later conducting research from a learning sciences perspective. As I am looking…
