Renowned educationalist Sir Tim Brighouse, observed that an outstanding school has four factors that are visible. "Teachers talk about teaching, teachers observe each other's practice, teachers plan, organize and evaluate their work together rather than separately and that teachers teach each other." He continues "One of the reasons I like that is that you can immediately see ways in which you could make it more likely that teachers talk about teaching."
Sir Tim then encouraged schools to focus on activities that were low effort but high impact, describing them as 'butterflies'. Some examples he gave included rotating staff meetings around different classrooms with the host, at the start, approaches. With modern technology teachers could observe their own lessons and then when viewing them back, decide whether they want to share them describing the room layout and displays or discussing other teaching techniques and with a mentor. The role of mentoring was vital and suggested that more schools could send teachers out in small groups to learn from colleagues in other schools. He said "If this were widespread practice, if people were to attend to their butterflies, the outcome in terms of teacher morale and teacher satisfaction would be positive. We all agree that professional development is the vital ingredient":
