This document outlines a school's plan to improve student learning and performance by focusing on strengthening the instructional core, which is composed of the teacher, student, and content. It describes the roles of each element and how changing one part necessarily changes the others. The school aims to collect fine-grained observational data on an identified focus of practice using non-judgmental descriptions. Teachers will then analyze the data, discuss findings, and develop action plans to enhance instruction and better engage students with content.
