The document describes two initiatives at George Spencer Academy to improve teaching and learning using educational research: 1. Visible Assessment using "yellow boxes" where students make improvements to assessed work based on teacher feedback. Teachers were trained to use highlighters to mark areas for improvement. Student and teacher surveys found the approach helped reflection and knowing how to progress. 2. Practitioner Enquiry where teachers identify an area for professional development and research best practices through observations, trials in their classroom, and writing a summary of impact. This is designed to lead to expertise, excellence and leadership. Key elements of learning highlighted from Hattie's research that could be the focus include feedback, mastery, collaboration and metacognitive strategies.
