Use Mentimeter to engage with an audience in real-time.  This might be to encourage feedback, in class sessions or at at events, or in any situation where you want to to pose questions to find out what a target group thinks.

Mentimeter provides many different question types to interact with your participants, including multiple-choice and free text.  Responses can be presented in a number of different formats, including graphically or by word cloud.

To get started go to http://www.mentimeter.com and set up an account.  Question creation is fairly simple.  Each set of questions is allocated a unique code.  Students use //govote.at to give their answers, identifying the set of questions from the unique code you give them.

Teacher uses Mentimeter to display responses in class. Mentimeter video channel here.
