QR Codes in the Classroom

About QR Codes

QR codes are those little square codes that you are starting to see on everything from movie posters to bananas. This technology is making its way to the classroom. This short article discusses what QR codes are and a few of the tools that  can be used to create them for the classroom.

The QR codes was first invented by a car parts supplier in Japan to aid in parts inventory. The code is made up of dark and light areas that can be read in two dimensions.


Regular barcodes as used in supermarkets and libraries are one dimensional. They are read horizontally and only contain a number.

 

QR codes are two dimensional and can be read in two directions. QR codes can contain binary information such as a URL or text. The more information you have the more complex the code.

How to Make your own QR Codes

There are a couple of sites that  I recommend you use to get started with QR codes in your classroom.
All are fairly similar in how they work you paste in the URL that you want to turn into a QR code and follow the directions. You can save the QR code by right clicking and choosing "save image as".

The image will be a .png file, you can copy and paste into a word document or save to your computer for later use on printed documents.
