A significant challenge to supporting student learning in the age of AI is miscommunication between instructors and students about appropriate use in a variety of contexts. To help with that challenge, our teaching center designed the Student GAI Use Scale. This session will share that student-centered scale as a resource for others along with feedback from instructors and students who have used it in their classes. Attendees will also be invited to share and brainstorm other key approaches and tools for effective communication between instructors and students to enhance the development of critical GAI literacies in learning environments.(Communication, AI Literacies, Ethical Use)
