Piazza is a collaborative question and answer platform designed to streamline course communication and enhance learning through peer-supported discussion. It creates a centralized hub where students can post questions about course content, assignments, or logistics, and receive answers from multiple sources—instructors, teaching assistants, and fellow students. Piazza's unique interface allows for both student and instructor contributions to responses, clearly distinguishing between official guidance and peer suggestions while encouraging collaborative knowledge building. Its wiki-style format enables continuous refinement of answers as understanding evolves, ensuring that the most accurate and comprehensive information rises to prominence. For instructors, Piazza provides valuable insights into student understanding through participation statistics, question patterns, and response timing, helping identify concepts that require additional clarification. With features like anonymous posting, endorsed answers, and real-time updates, Piazza creates an inclusive, responsive learning community that extends classroom discussions beyond physical and temporal boundaries.
