IQ Poll

When I teach, I often need to ensure that specific knowledge is understood by everyone in the class.

There is a few free online systems at the internet to help me with that. This one is IQ Poll.  

1. You sign up and get as an access to your own online portal
2. You create a question and some answers
3. Put the direct link (you get from the system) up on you powerpoint or smart board
4. Students can reply on their mobile phone or on their laptop

It is completely anonymous.

I've made a little video. Its in danish, but you still get a nice feeling about how it works!
