Building Thinking Classrooms (BTC) has transformed how teachers design and facilitate learning, helping students move from passive compliance to active engagement and deep understanding. However, sustaining BTC practices requires more than individual teacher effort—it demands leadership vision, structures, and culture that support experimentation, collaboration, and professional growth. This workshop is designed for school and district leaders who want to understand the leadership moves that make BTC sustainable and scalable. Participants will explore how to create the conditions where teachers feel supported to take risks, learn from one another, and continually refine their practice in service of student thinking by analyzing the model used by the presenters. Participants will also be given an opportunity to share their suggestions and struggles with implementing adaptive changes of this nature.
