I currently use QR codes to hold the warm-up questions so students have something to do when they come in and I use it to put the answers on the homework but while giving a test today, I wondered if there was a way to use QR codes for students to relay their answers to me.
I have used a QR code maker on the iPads in class with the students in the past. I've asked a question or put a mathematical problem on the board and had them create the answer in that app. I would use a QR code reader to check the answer as they left.
Sometimes I would like to keep the information or receive all the quiz answers. I need to find out if I can have them either e-mail the QR code to me, have it loaded up to schoology, put in dropbox or maybe use the airdrop feature to send the codes to me. I am working on ways to save paper but I also wonder if requiring answers only is a good thing for Math.
On the other hand, I could have them download the quiz, write on it to show their work and then upload the completed work. Gives me food for thought over the next few days.
