After a few days of computer science/coding related post, we’ll go to the “front end” and look at a very smart application of those programming possibilities. In my January 11th post I discussed how trends are always a few months behind in education as teachers find way to use the hippest and hottest tech out there (apparently my lingo is also a bit behind), QR (Quick Response) Codes are a great example of taking a while in the education world, but I would argue that they still haven’t completely had there day in the “regular world” either.
February 24th – QR Codes
For those of you who are unfamiliar, QR Codes are those perfect square boxes with the random black and white squares that sometime have a logo in the middle. You’ll have to download an app on your SmartPhone to scan them and it’ll take you directly to a URL (website) and thats a great and easy way to save paper. QR Codes are terribly handy and should be more available, the problem is you have to download software to access them (come on Apple, get it together!)
QR Codes work through a type of binary system with either the combination of black squares filled in and then the scanning software recognizes it and goes to the appropriate page. There are dozens of explanations online, here is one of my favorites.
For an educational use, think about saving student work into a Google Drive folder then creating a QR Code from that long shared Folder URL that you get. Simply visit a QR Code Creator (QR Code Generator is great) and paste the long URL to get the QR Code, save the JPG and print, then paste on a bulletin board for everyone to scan and see student work. Another great way to use them is a student scavenger hunt that gives clues around the school to get to know areas or what certain rooms are used for.
There is also a great Chrome Extension that can create a link and QR for you – it’s called Goo.gl URL Shortener (pretty spot on) and available in the Google Chrome Store. AND the Google shortener also provides a QR code when you shorten anything – really there is no excuse not to use it.
