Jacqueline asked me to post this
QR Code generator:
http://zxing.appspot.com/generator/
Maybe QR codes can be used to give individual students access to answer keys on the overhead screen in class, once they have completed an exercise.
Or if students are out in the field, QR codes can be placed at specific locations that they need to get to, giving hints to the next location they need to find (treasure hunt).
Could QR codes be used to enhance learning and improve access to learning resources?
You could use QR codes for voting. I.E. scan this QR code to vote for A and scan that QR code to vote for B. In the background the websites attached to the QR codes could increment the count each time they are called.
Recently I noticed that at BCIT they are using QR codes in the washrooms. There is a sign that says, scan this QR code to send a text message to Facilities if this washroom needs cleaning. You could use the same idea to send an email or a text message to notify an instructor that someone is at a particular location.
