Iphone X Google Docs X QR Codes = Grading an entire class from 1 sheet of paper!


As I am borderline obsessed with coming up with ideas on how to harness the power of QR codes for my classroom and education, I think I may have come up with a viable concept.  The basic idea is to be able to use my iphone to read student work from the comfort of my couch or coffee shop.  Here goes...

1. Have students complete their work using google docs.  When the work is complete, make sure they change the privacy settings to "anyone with the link" instead of private.
2. Students then visit a QR Code generator website (Kaywa, Delivr, Qrstuff) and turn their work into a QR Code.
3. When the code is done, students then visit a public & editable google doc that is created ahead of time by the teacher.  The google doc would have a table inserted ahead of time by the teacher where each student could insert their code & name.
4. When the table is full and the students have completed their work, the teacher just needs to print out one sheet of paper instead of carry an entire class set of work home.
5. The best part...sit on your couch with an iphone (or any smartphone w/ QR Code reader), scan one code at a time, read through the work and place a grade on the sheet of paper or gradebook.

*Important Update: In attempting to pull off this idea I just came across a few important tips:
1. Use the Kaywa QR Code generator.  Choose the small size code.
2. Have students shorten the URL to their google doc.  The shorter URL allows for a simpler QR Code that can be decoded by a QR Code reader with better accuracy.
3. QR Codes can't be copied and pasted into a Google Doc.  Students must save their QR Code as an image, and then insert the image into the table on the Google Doc.

Of course the one downfall to the system is that you can't leave feedback on the assignment.  Therefore, this option might be best for assignments that don't require extensive comments from the teacher.

I think I'll be trying this idea out this week!


  1. This is an amazing idea. I want to try it!

  2. Why can't the students just share the google doc with their teacher?
