The document discusses teacher retention issues in the UK and a research project to address these issues. It found that over 10 years, 12% of new teachers left after 1 year and 28% left within 5 years. Reasons for leaving included high workload, lack of support, and stress. The project developed a toolbox with two tools to support teacher collaboration and resilience: 1) a framework for collaborative dialogue to structure conversations around challenges, and 2) lesson study where teachers collaboratively plan and observe lessons. Initial findings found the tools helped frame discussions and promoted collaboration, but challenges included lack of time and potential workload increases.
