I love using Piazza for answering student questions; the user interface is unbelievably nicer than anything else I've seen. It is easy to enter text and easy to see what questions need answering; It is just easy to use.
Thank you for Piazza! It has been an excellent resource for our new introductory biology courses here at Yale. Piazza is a great forum for those students who are too shy to ask questions in class and who post anonymously - and then this benefits all the students who read the answers. Plus, I have had students say that they love how quickly their questions get answered, instead of waiting for office hours or the next lecture.
Piazza is the best discussion forum I've ever used in my 400-strong enrollment class (CS125). It encourages students to work together and to discuss concepts and misconceptions together in a timely, coherent and easily searchable format. If you're not using Piazza to help your students learn and deeply connect with the course content - then your students are missing out and the ability for yourself, TAs and others to support individual students and the class as a whole will be diminished.
Instructors can create a Piazza for their class with a single click.
Students and instructors are automatically enrolled with appropriate roles, based on the course roster.
When clicking on Piazza in Trunk, users are automatically signed in to Piazza, so there's no need to remember a separate user name and password.
