Clickers are small hand held devices that resemble remote controls used by the audience to give feedback to a presenter.

Approximately 40 of them are in stock, so they can be distributed to a moderately large class. The software can be incorporated as part of a presentation, or stand alone and allow live results and graphical statistics from a polling or quiz to be demonstrated in front of a class.  Help with the integration of clickers into lectures and activities is also available.
