There are two types of them:
- text based (provide URLs or e-mails, for online web pages, articles, videos, music ...) (QR code creator)
- voice based (provide TTS content, or online voice files) (QR voice code creator)
There are diferent QR code readers, for me i-Nigma code reader proved to be one of the best and works well on tablets and smart phones.
They can be used for different educational purposes for example:
- they can label artworks at the exhibition to explain the techniques and the topics of the artworks for example (voice or text based ones),
- they can be used for treasure hunt (describibng the way to the treasure),
- they can be used for web searching for specific topics,
- they can be used for language learning (listening and reading)
- they can be used outdoor (in the natural park or learning path to describe plants and animals in the environment)
- use your imagination and ideas :) ...
It's important, that QR codes can be generated by teachers and students, so they can also be used in different projects.
Here are my examples of QR code use in the classroom.
- About food - (used in the secondary school)
- Saami people Finland (teacher training course)
- Traffic signs
I also prepared a presentation in Mentormob on the topic
