Packback is an AI-powered discussion platform designed to foster critical thinking and meaningful academic discourse through guided questioning and peer interaction. Unlike traditional discussion boards, Packback encourages students to pose thoughtful, open-ended questions that stimulate curiosity and deep engagement with course concepts. Its proprietary AI system evaluates posts for depth, credibility, curiosity, and presentation, providing instant feedback to help students improve their contributions before submission. This scaffolded approach helps students develop more sophisticated critical thinking and communication skills over time. For instructors, Packback automates the administrative aspects of managing discussions while providing detailed analytics on student participation, question quality, and engagement patterns. The platform's emphasis on curiosity-driven inquiry creates a student-centered learning community where meaningful exploration of ideas takes precedence over simplistic answers or superficial participation.
