Student Response Systems

iClicker 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 iClicker (available from USC Bookstore) or the mobile app, REEF Polling, on their smart phone to respond to your questions.

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


  • Instructor interface works on Windows and Mac operating systems
  • Integrates with PowerPoint via a floating toolbar
  • Polling captures real time student responses and displays them
  • Students register their device online for your class; view participant lists
  • Student devices display correct/incorrect answers; can be reviewed later
  • Transfer student scores to your Blackboard Grade Center

  • WinMac: The WinMac version is for faculty who use both Windows and Mac. It contains the executable files for both Windows and Mac iClicker.

This allows faculty to have one iClicker folder and one iClicker class data location for multi-platform use.
