Using QR codes in education

New technology for the science classroom

QR codes might sound scarily complicated - they did to me at first - but they're surprisingly easy to use and can be an informative and fun addition to the classroom.

What is a QR code?

A QR code is a barcode which can be read by webcams or smart phones. Smart phones require a free app, such as Red Laser, to scan the barcode. When the barcode is scanned, information appears on the phone screen or computer. This information can be text, a web address, an email address or a video. You can generate your own QR codes, using a website such as QRStuff, and put them in worksheets, in emails and online. Have a look at the QR code I made as an example:


How can you use QR codes in schools?

Check out the Classroom in the Cloud blog for some great ideas using QR codes. How about using an interactive whitebord to record lesson notes and key ideas? You can put the video online and add a QR code to a homework assignment so that students can go over the lesson at home.

You could create a puzzle-solving lesson out of QR codes. Put QR codes around the school building - each QR code leads to a new science based clue. The clue leads the students to the next QR code - it's a 21st century treasure hunt!

What about a Periodic Table of QR codes for your classroom? Brady Haran from Periodic Videos, has created a periodic table with QR codes in place of the elements. Each QR code takes you to a video about the appropriate element.

To download the high resolution version of the Periodic Table of QR codes, go to the Periodic Videos Flickr photostream.
