Student Response Systems

i>Clicker and REEF

Student response systems allow you to take attendance, and poll students in real time with questions projected in your classroom. You can track answers, automatically add scores to your Blackboard Grade Center, and even allow your students to review in-class questions for study. Students can use either a purchased i>clicker (available from USC Bookstore) or the mobile app, REEF Polling, on their smart phone to respond to your questions.

UTS support for i>clicker/REEF systems is confined to providing university-specific software for the i>clicker system.

  • Integrates with PowerPoint via a floating toolbar
  • Polling captures real time student responses and displays them

i>clicker Software

  • To download the current USC i>clicker software, click on the link below that matches your computer’s operating system:
  • Mac
  • Windows
  • WinMac: The WinMac version is for faculty who use both Windows and Mac. It contains the executable files for both Windows and Mac i>clicker. It must be downloaded and extracted and moved to a USB drive using a Macintosh computer, but thereafter is accessible by Mac and PC. This allows faculty to have one i>clicker folder and one i>clicker class data location for multi-platform use.
