We were very happy with Piazza in CS 142 so I'd give it a strong positive recommendation. It's easy-to-use, the students really enjoyed it (particularly in comparison to the newsgroup approach we used in previous offerings of the class), it was reliable, and the course staff liked it. We'll definitely use it again.

After a semester of using Piazza, I can truly say I loved it. The TAs loved it. I can't speak for the students, but I know that they got answers to their questions a lot more quickly. With Piazza I got a real-time picture of what was going on, and could address some of the really important misunderstandings in class.

Piazza has become the single source of truth about all our course-related information. I've never seen a tool that so directly hits the nail on the head in terms of every information-flow problem I've been struggling with for the 19 years I've been teaching.

Piazza has proven to be an ideal forum for my class. Compared to conventional bulletin boards, the design makes it much easier for students to find relevant posts, and for my staff and me to keep track of outstanding questions. On top of this, the folks at Piazza have been wonderfully supportive and very responsive to our needs.

As a lecturer for a large class, what I like best about Piazza is that my teaching assistants spend significantly less time answering repetitious questions from students, or correcting simple errors. Now they can spend more time helping me create new material for the class.

Thank you for the nice gift of the Piazza end-of-term reports for my three classes. And for all the improvements to the software that were happening all term, right before my students’ eyes!

Piazza has been a substantial upgrade to our prior use of newsgroups for communication with and amongst the students in the class. Piazza attracts significantly higher student participation and has enabled us to better encourage and reward such participation.

One student wrote in anonymously on Piazza to complain a take-home exam interfered with a big event at their fraternity. Several other students wrote in to tell the complaining student to stop whining, that there's plenty of time for the exam if they only budget their time. In the past, I've always had to respond myself. With Piazza the student's peers did it for me.

Before, I answered hundreds of emails each semester, about assignments, tests, and so on. Now, I get an email from Piazza about a new post, take a look, and often find that a student or another staff member has already answered it. Everyone is more engaged. Everyone is happier and more positive about the course.

Piazza is great to use at the community college level! After using Piazza for a few semesters, it is now a requirement for all of my face-to-face and distance learning courses. Students enrolled in my courses are engaged, learning, and helping each other learn.

Piazza is definitely a big improvement on the university-provided discussion groups we're accustomed to using because we can faithfully represent the instructional roles and organizational system that we use in teaching. All the other advantages of Piazza are gravy!
