ab: Summary: This article documents the classroom mathematical practices
observed in a collegiate level teacher education course related to the
circle topic. The course, which was prepared as design research,
utilized a dynamic geometry environment which influenced the type and
nature of the evolved mathematical practices. The study uses emergent
perspective as the theoretical framework and Toulminâ€™s model of
argumentation to analyze social interactions within the classroom.
Findings reveal three sequentially emergent mathematical practices that
are in increasing order of complexity. The significance of this
analysis stems from the fact that it contributes to an emerging body of
knowledge on inquiry-based and technology-supported teaching in social
contexts for which more research is needed.
