What Are They:mobile-zebra2.gif

hese codes contain small blocks, similar to dots, instead of the simple bars when put together and scanned contain information.Everyone's seen the one-dimensional bar code on tags for items you purchase. The updated version of that is the, Quick Response (or QR) codes.

These two-dimensional QR codes were first created in 1994, to track vehicles during the manufacturing process at high speed. In 2002, Japanese wanted to turn everyone’s phone camera into a bar code scanner for marketing purposes. QR codes store information in the amount of 4k (roughly one page of text).

Andy Ramsden of Bath University’s Head of E-Learning has a working paper on The use of QR codes in Education and it's a great starting place if you've never used them.

What's Needed to Create:

What Students Need:
  • A Device with ANY QR Code Reader – students can search through their carrier’s marketplace and download the app.
  • Alternative – hyperlink if your QR code is online and give the URL address if printed.
  • NOTE for teachers: prior to using QR codes in the classroom, survey your students and perhaps pair them up so that each pair of students has at least one device.


Ways to Use QR Codes in the Classroom:
1. Teacher Info – forget handing out business cards or writing your information on the board…attach your teacher info to a QR code and send it to parents.

2. Presentation Feedback - QR Codes can also be used for obtaining instant student feedback. When students scan the YES or NO code, a pre-written SMS goes to an SMS service which can be accessed by the presenter via a web page. It can also link to a site like Padlet (formerly Wall Wisher) to show audience/classroom response
s to a prompt.

3. RSS News Feed Subscription- Allow students to easily and instantly subscribe to your blog’s RSS feed updates. Just generate a QR code using your feed URL, and display it in Blackboard, or on your website. Students can scan to subscribe.

Homework Directions


4. Homework Reminders, Remarks, Directions - Teachers can embed their homework assignments into QR codes. Just paste the code onto the virtual classroom whiteboard, e4 Blackboard class, website or posted on the wall and let students scan it. The link could be to an actual worksheet, a video that explains assignment or directions for students. Students can even send you their completed work in the form of their own QR code.

5. Link to Notes - Class notes can be encrypted in QR codes so students can pay more attention during the lecture.

6. Connecting to Parents - Create a document, website or other information and give it a QR code. Send it home to parents or post the QR code in on your website. You can even make a QR code for your website or to an updated Google document you update regularly with what's happening in the class.


7. Important Info Needed as a Resource….a Periodic Table, Formula Chart, or some piece of info your students MUST use as resource for their lesson, a story, a website, current event, review, etc.

8. Extra Information Used in Course Content - QR codes can be added to course content for extra pizzazz. If you have online courses, classes, tutorials, tests or other resources relevant to the syllabus, that you want students to access, you can create a QR code for each resource. Teachers can embed QR codes into PowerPoint slides, course material, handouts, syllabus documents, webinars, class downloads, and onto whiteboards.

9. Treasure Hunts of Learning– create a scavenger hunt for students to give them info or figure out answers by giving them clues. They will be so excited to do their work.

10. Link to Homework or Assignment - link to more information to guide a student through homework or a class assignment.

11. Link to a Video - a video could be of you giving directions on a project, a video from BrainPoP, from your textbook, or any other informational video to help students.

12. Link to an Online Forum, Backchannel, etc. - Chatzy, Today's Meet, Think Binder etc.

13. Book Overview – a QR code placed on the back cover of a book could have an overview of the book or other readers from students.

14. On Bottom of a Document
    • Bibliography of student work - Create a page on your wiki or blog, or craft an email or a handout to give to parents that includes links to student work. Along with the links, put a QR code for each of the virtual projects. This way, viewers have the option to view immediately via their smartphone, and if they are viewing a print version, they don't have to enter the URL into a computer.
    • Link to additional resources for class materials
    • Inspirational quote up in your classroom? Include a code that brings up a photograph of the author.
    • Have a classical poem up instead of a quote? Use a code that takes you to a podcast of the poem.
    • Music teachers can create codes that link to music podcast. When you're playing a particular piece in class, attach the related code on the music itself, so students can listen to the recording at home.
    • Reports & Projects - With any assigned book or reading, include QR codes linking to book reviews. Include codes to the online versions of your assignments, your classroom's calendar of events with upcoming due dates, or related videos, articles, etc

15. As a Warm-up – have a prompt or warm-up ready for students to scan for their warm-up.

16. Extension Activities to Reading put QR codes in reading books that the children take home. These could link to online comprehension questions for parents or to websites that children can use to find out more information about the books or to related games that they can play.

17. Link to "Additional Information" on a Project Display – add additional information to a student's displayed work. This could be a video of the student evaluating the project, or additional information to an art display about the artist, or work.

18. Advertising – place QR codes in the advertising the yearbook, an event, etc.

19. Answer Checking Stations – place them outside the door or along the walls and allow students to check their answers by clicking on the QR code to get the answers.

20. To Explore a Physical Model – place QR Codes onto objects to explain parts of the object. Ex. on a skeleton QR code each bone explaining what it is or maybe what it functions as.
