Lesson study : a professional learning model that actually makes a difference

Over the past year, a group of mathematics teachers from one Victorian school engaged in a process of professional learning called Lesson Study. In bi-weekly meetings that focused on the development of a single exemplary lesson, they questioned, pondered, discussed, debated, explored, and examined mathematics, and the teaching and learning of mathematics. This paper describes the process and the outcomes of what these teachers consider to be the most powerful professional learning they have experienced.
