Research is a universally acknowledged tool in and for education. This study investigates the enablers and outcomes of research productivity of high school mathematics teachers. Using partial least square structural equation modelling, data from 211 tenth-grade mathematics teachers of five public schools divisions in the northeastern part of…

Conceptualizing lesson study as an encounter at the boundaries of research and practice, this study examined teacher-academic collaboration for its potential to shape teacher research identity. We report here a case study of a school where the teachers have been able to present their lesson study works in conferences. Documents produced by the…

This article delves into moments of affect, puncturing the exchanges between an early career 2SLGBTQ+ researcher and a group of Canadian adolescents, mostly composed of girls, who developed a ClayMation video to take the pulse of emerging vibrancies in maker literacies. Among these dynamisms came the matter of gender in the research project.…

The authors examined the research and activism of 10th graders (ages 15-16) involved in a youth participatory action research project in a course in qualitative research at their small public school in New York City, New York. The authors, a classroom researcher and a high school teacher, looked closely at how the youth researchers used…

This paper is about memory, the elusive process of remembering and of an encounter between a researcher and a participant who after five years reunited to remember. The object under study is a high school social justice curriculum with a central focus on the development of social action projects. Grounded in Pitt and Britzman's work on difficult…

For students in biology, chemistry, or environmental science, diatoms offer excellent insight into watershed health and human impact on the environment. Diatoms are found globally in virtually every habitat that has sunlight and moisture, including polar seas, tropical streams, and on moist soils and mosses. Studying diatoms as biological…
