QR stands for Quick Response, as you get the information quickly from the QR code and onto your mobile device; tablet or cell phone. They are black and white square symbols that a QR reader, installed on your cell phone or other model device, can read.

When the QR opens, it takes the learner quickly and instantly to where you, the teacher want him / her to be: could be a clue or answer to a question as a piece of text, link to a website, phone number or email address, link to social network, such as Twitter or Facebook page.

  • Trees on School Property - an environmental awareness, about out creating QR codes containing information about the indigenous trees on the school property. Below is an example of a link about a tree - scan it to find out the information.
