Piazza leverages the power of the community – student answers are collaborative spaces for all students to build a single high-quality response; Instructor answers are collaborative spaces for all instructors to build a single high-quality response.
Instructors can post announcements to their class by posting a note (not a question) on Piazza. Notes do not need an answer, and are often a great way to update the class of a change in oce hours, a typo in the homework, and so on.
By default, resources you upload are private (only viewable tologged-in users), so if you wish to make them public (viewable bynon-logged-in users), you can adjust the setting from your ManageClass page.
Questions and answers on Piazza are community-edited – a student can edit another student’s question, as well as the collaborative students’ answer (note the position of the apostrophe). An instructor can edit a student’s question, the collaborative instructors’ answer, as well as the collaborative students’ answer. A history slider at the top of each post lets users see how thequestion and answer have evolved over time. If instructors do not approve of any posted content, they can edit the content and disable the history, or delete the content altogether.
