Who’s killing your professional learning community? In this simulation, you will be involved in a real-life murder mystery as you listen to suspects, gather clues, and try to identify culprits who have “done in” efforts to establish systemic staff development and professional learning communities. You will examine “pitfalls” including attitudes and practices that kill collaborative culture, bring continuous improvement to a halt, and stand in the way of student learning. Key strategies to enhance student learning through collaborative teams will be shared.
