Professor Hattie’s books serve as a basis for discussion on using evidence to inform your teaching and leadership practice, and the systems in which these practices are supported. One example might be the degree to which the school has developed a clear picture of the type of feedback culture and practice that we aspire to have. This can assist teachers to optimize their feedback and heighten students’ awareness of the benefits of effective feedback. Similarly, it can help leaders optimize their feedback and boost teachers’ awareness of the benefits of feedback. Both of these actions serve to create an awareness of how feedback might be getting through to each of these key stakeholders.
