Using clickers (student response systems) or online tests is a great way to get immediate assessment results for your students. However, when you only have one iPad, how can you possibly get results from all your students? I have come across an app I am very excited about called Plickers (like "paper clickers"). With this app each student gets their own card with an augmented reality trigger on it. Students can turn the card to indicate different answer choices. The teacher uses the app to scan the room and gets feedback on each student's choice. You can download the cards on the website here. I also designed backs for the cards so it would be easier for younger students to figure out how to hold them.
