What is Piazza?

Piazza is an online platform that facilitates communication among students and instructors.  It’s main purpose is as a question and answer discussion board that facilitates collaborative solutions.  A unique feature of Piazza is the format for student questions that the instructor might otherwise receive via email. Students ask questions that all instructors and students can see. Then, Piazza leverages the student community, allowing students to create a single answer to the question. Likewise, instructors can collaborate to create a single answer to the question. Instructors can also endorse student answers that do a sufficient job of answering the questions. A history slider allows a user to see how an answer has evolved over time.  

Piazza has additional uses and features, such as:

  • Announcements
  • Class files and resources
  • Polling
  • Private message capabilities
  • Participation statistics
  • Folders for questions about different topics

What is the purpose of Piazza?

Piazza is a question and answer discussion board. It can be used to replace most email communication related to your course.  Students can ask and answer any kind of question, for example, about homework, about details of an assignment, or about the syllabus.  For instructors, the tool is intended to improve email workflow. For students, the purpose is to get faster responses (since students may answer before an instructor would), to practice application of knowledge (in response to questions about homework), and to build a community.
