Piazza: social networking for courses

Professors in several departments at BU (including Computer Science, Chemistry, Physics, and Mechanical Engineering) often use the free social discussion tool Piazza in their courses. Piazza is free, and allows threaded discussions to happen in a user-friendly way. Students in these courses are encouraged to post their course-related questions on Piazza, significantly reducing emails that are directed to the course staff. Questions posted on Piazza are then answered by the course staff, or, in many cases, by other students. Questions posed in these courses have ranged from logistical issues (“Which lab are we doing this week?”) to conceptual issues from students grappling with the material (“I tried solving problem 3 this way, but it didn’t work – can someone point me in the right direction?”) The latter are particularly good at drawing multiple students into the discussion.

Piazza can help you keep on top of what’s going on in your course, while at the same time reducing the amount of time you spend responding to students over email. Piazza posts can be read on the web site, whose features make it easy to see which posts need an instructor’s attention. They can also be viewed and responded to through the Piazza app on your favorite mobile device. You can also choose to get updates from Piazza via email. BU IS&T does not offer support for Piazza, but it is an interesting option for professors who feel comfortable exploring free online teaching tools.
