An alternative to PollEverywhere or Clickers

If you teach a large introductory course and are very interested in being able to use PollEverywhere, clickers, or something equivalent for in-class real time responses, you might consider the Q&A Poll tool in Piazza.

Piazza is a platform which offers functionality beyond the discussion boards. Duke Sakai offers a Piazza integration that makes it possible to set up a Piazza site within your Sakai course site. Piazza supports in-class, real-time responses via in-class polls. The tool enables students to ask questions and contribute to responses while allowing instructors to control and organize the community (and provide quality answers).  Students can use their laptops or mobile devices (Piazza’s mobile application is available for iOS and Android) to access their class and answer the questions being asked by the instructor.
