Changes of Teachers’ discursive practices learning dynamic mathematics in a collaborative, online environment

Abstract

Using data from an inservice professional development course, we inquire into changes in secondary teachers’ discursive practices in a latter part of the course compared to the beginning of the course. Participants interacted in a collaborative online environment, known as Virtual Math Teams with GeoGebra (VMTwG), focusing on discursive, mathematical, and collaborative practices. From a sociocultural perspective, we believe that teachers gradually develop their Technological Pedagogical Content Knowledge (TPACK) by interacting discursively in small teams. Using conventional content analysis of the teachers’ review of their recorded discourse, we investigate changes in practices from the teachers’ perspective. Our results show that teachers perceived that their discursive practices differed importantly from their practices at the beginning of the course.
