In this supplement, we plan to recruit two "master teachers" who will participate in the summer Institute-2024, along with the newly recruited teachers. The "master teachers" are the returning teachers who fulfill a different niche in the community over the summer than the grant leadership, faculty mentors, or graduate student mentors can - that of near-peer role-models in the integration of computational content in the K12 curriculum. These master teachers are in effect coaches who are also local educators who can make meaning with their peers and form relationships to support teacher advancement in the program.
