• Set up Piazza for your course before the semester starts 
• Develop and communicate your course policy regarding student communication with you and/or TAs. Examples: 
  • No homework questions by email — use Piazza.
  • No email, except for emergency or confidential communications — use Piazza.
  • Offer demonstrations of Piazza use, or give a low-stakes assignment to practice use by creating and responding to introductory posts.
  • Develop monitoring practices, such as:
    • Assign Piazza monitoring hours to Teaching Assistants.
    • Set standards for expectations of TA responses.
    • Don't answer questions right away; give students time to respond.
    • Require students to search first before asking their questions.
    • Consider offering extra credit to students who post the correct responses to classmates’ questions.
    • Consider developing an FAQ or posts of resources in Piazza, such as practice exams, as a backup to the course.
