Piazza is a Q&A web service. It can be described as “mixture between a wiki and a forum” that can be used with learning management systems. Instructors can create a free virtual class and send out access codes to students. Students and the instructor can then create posts with questions. Everyone can join in to supply answers, hints, or discussion. Studies show that students are more likely to supply hints and help the original poster arrive at the answer themselves because they are also interested in learning the material. The instructor can moderate posts to correct mistakes and misinformation, but students posts generally receive responses much more quickly and with more detail than if each student asks the instructor directly.
Piazza integrates with every major LMS (Learning Management System, i.e. Moodle, Blackboard, etc).
