Developing a sustainable and scalable model for the professional learning of mathematics teachers: Final report of the LeMaPS (Lessons for Mathematical Problem Solving) Project

The LeMaPS project, in the period 2014-16, worked with clusters of schools and wider networks in England to introduce Lesson Study processes with an emphasis on developing the teaching of mathematical problem-solving. Fundamental to the project was the intention to use a high-quality approach incorporating the essential principles of the Japanese model of Lesson Study. The work of the project was guided by research questions that focused on scalability and sustainability and how best to support the developing groups of teachers.
