The document summarizes a staff development meeting at Elthorne Park school focused on action research clusters. It describes three clusters: stretch and challenge for all, marking and feedback, and interventions for underachieving groups. For each cluster, teachers will meet to discuss readings, decide on observation criteria, and determine individual lines of inquiry. Follow up meetings will have teachers sharing new resources, conducting peer observations, and formally presenting findings to shape their practice. The goal is for collaborative action research to improve student outcomes.
