The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis-of-practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two “lenses,” a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science teaching and learning and to improve teaching practices in this year-long program. Participants included 48 teachers (n = 32 experimental, n = 16 control) and 1,490 students.

By synthesizing what has been learned with regard to critical dimensions of mathematics classroom teaching and learning, and investigating the ways teachers and other school personnel characterize high-quality mathematics instruction, this study defines the notion of ‘instructional vision’ and provides an initial categorization scheme.
Note: A previous version of this paper was presented at the National Council of Teachers of Mathematics Research Pre-Session in San Diego (April 2010) and the Annual Meeting of the American Educational Research Association in Denver (April 2010).
In this article, we present an analytical approach for documenting the identities for teaching that mathematics teachers negotiate as they participate in two or more communities that define high-quality teaching differently. Drawing on data from the first two years of a collaboration with a group of middle-school mathematics teachers, we focus on a critical initial condition for teachers to improve their practice—determining that the effort required is worthwhile.

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.
