This document discusses action research and its various forms in education. Action research involves teachers identifying issues in their practice, gathering and analyzing data, and making changes to improve outcomes. It can be conducted individually or collaboratively at different levels from a single classroom to district-wide. Benefits include improved instruction, assessment, and policies informed by evidence. Support may be needed for coaching, technology assistance, substitutes or release time depending on the scope. Potential impacts range from changes in a teacher's curriculum to reforming organizational structures across a district.
