Just tried to use a QR Code with my sixth form class for no other reason than to judge their reaction.
Surprisingly none of them new what it was! Therefore the homework was two fold, 1) figure out what I had just given them and 2) Complete the "hidden" homework.
If you have any ideas of how to use QR Codes more constructively in a lesson I would be grateful to hear from you. I can see potetntial in it but my brain has gone to sleep.....ZZZZZZZZ.
