Circles is designed to enhance teacher training by forming small, peer-driven study groups called “Circles.” These groups, consisting of up to five teachers, participate in regular self-managed study sessions throughout their courses. The app facilitates matching based on shared goals and interests, handles scheduling to ensure meetings fit into each person’s free time, and provides course materials designed to foster active learning and mutual support. Additionally, it enables course administrators to give feedback on weekly assignments using an AI assistant. This solution offers school districts and networks a cost-effective, hassle free alternative for large-scale, effective teacher training.
