We assessed the teachers' developing interpretive power, specifically developing…

This paper examines the pedagogical and organisational changes three lead teachers made to their statistics teaching and learning programs.

This study examines the learning of a diverse team of five professional developers as they led or supported a mathematics initiative. Although teachers are typically the focus of learning in professional development, we contend that the learning of professional developers is important and should not be overlooked. We examined our learning as a…

This article describes a specific approach to a teacher investigation of students' written work. The aim of the investigation was for in-service middle school teachers to externalize their thinking about their students' mathematical thinking and to then reflect upon these externalizations and make refinements accordingly. This aim mirrors the…
