Over the past few days, our class has been trying a question response system called: Plickers.com. Plickers (similar to socrative.com which we have used in class before) allows students to answer questions by holding up a card (simliar to a QR code). They can respond to multiple choice questions by holding the card up in a certain way (hold it one way to choose answer A, hold it another way and you will choose answer B etc.). Once they hold up their card, I then use the camera on my iPhone or iPad to capture their answers. Their answers are then displayed as a graph at the front of the class. So far, we have used the Plickers response system to answer math questions about measurement as well as grammar questions about contractions.
