This video on QR codes for periodic tables shows you there is sound educational value in developing QR codes but we are at the stage where it will be labour intensive in some respects to get some decent value out of QR codes. The high resolution image of the tables is here. It’s extraordinary and a totally different way of thinking about how you can share information and then putting mobile technology at the centre of it. If you are like me and you are still not sure how you could use them in your classroom, then let me share some good sites with you. WIZIQ gives you a no nonsense explanation and some examples of QR codes to try. Cool Cat Teacher Blog has some very hands on material because Cool Cat Teacher is a teacher and so has had a comprehensive look at what QR codes can and cannot do in a classroom and the sorts of problems you might be faced with. There are some good practical applications on the site. Best Colleges Online has a number of very practical ideas for QR codes with further links out which will probably get you thinking about what you can do with QR codes. ITBabble has an excellent discussion of the QR codes to highlight whether they really do have any real value and perhaps are just something which might create social injustice or isolation and then extra work. This article provides the balance to the discussion so you go about your thinking of QR codes with your feet on the ground! I plan to try them and the thought of being able to put QR codes on a slide show and have the students actively involved with that appeals to me. The value, the use, the point and the purpose will become clearer to me when I get QR codes for a trial in my classroom. Two things are selling them to me at the moment:
1. Students like using their mobile phones and QR codes could make good use of them.
2. QR codes save paper and other resources. I am all for that.
