Lesson study library: A catalyst for incremental instructional improvement
This project creates a digital archive for lesson study materials created by mathematics teacher teams working to deepen their understanding of content and instructional strategies associated with the Common Core State Standards for Mathematics. The archive serves as a digital library, searchable by grade level, domain, content standard, standard for mathematics practice, and other criteria. Teacher teams may use this library as a starting point for their own action research, or lesson study, on a particular learning objective. In addition to retrieving existing lesson study documents, users may submit the data from their own team’s lesson study. This growing knowledge-base of mathematics resources serves to support teachers as they work to increase student achievement and deepen student understanding of mathematics at every grade level.
