District Development as a Means of Improving Mathematics Teaching and Learning at Scale
This chapter focuses on research that can inform the improvement of mathematics teaching and learning at scale. In educational contexts, improvement at scale refers to the process of taking an instructional innovation that has proved effective in supporting students’ learning in a small number of classrooms and reproducing that success in a large number of classrooms. We first argue that such research should view mathematics teachers’ instructional practices as situated in the institutional settings of the schools and broader administrative jurisdictions in which they work.
