Transforming the world of teacher evaluation/observation one school at a time through Trust-Based Observations. Improving teaching, learning, and teacher retention while creating cultures of trust. When school leaders create conditions of trust so that teachers know they can be observed trying something new that is a disaster, yet know they will be praised for taking a risk, the result is teachers persisting in taking big risks to grow their practice. The result is teaching and learning growth and what John Hattie says about TBO, “collective teacher efficacy in action.” Teachers, feeling empowered and supported stay.TBO succeeds by focusing on engaging in collegial dialog driven by questions about actions taken and that could be changed to help students learn, as well as the sharing of observed strengths identified by the manageable observation form and its nine core areas of pedagogy. Teachers frequently finish the reflective conversations that follow the observation by saying they’re already thinking about what to get better at without even being told. They then use the revolutionary double feature of the form as a hyperlinked professional development tool to make those improvements.
