QR Codes in K: Capture the Voice

The following activity was my first successful attempt at using QR Codes in the classroom. You can use QR Codes in many ways but I specifically wanted to use them to capture the voices of my students explaining imaginary people they created.

The students practiced verbally explaining their people throughout the entire process of our culminating task. This was important, because if you leave practicing how to speak in a second language until the END of your task, you’re pretty much hooped. Practice is essential.

The students planned their people out, painted the backgrounds, drew their people, painted their skin and clothing, and drew and painted the finishing details.




When they were all finished, they looked beautiful. We then added the QR Codes.


Here’s how we went about it.
I used the app “Croak It” (on my iPad) because Audio Boo wouldn’t allow me enough storage unless I upgraded my account, which I wasn’t about to do. Croak It’s set back was that each student was only able to record for 30 seconds. This is where the oral language component gets differentiated. I had some students who could explain their person’s name, eye colour, hair colour, shirt colour, pant colour, and shoe colour in 30 seconds. I had other students who could only do one or two of the above. The 30 seconds was kind of nice as a teacher as well. Limiting the recording time to 30 seconds means this activity was relatively quick, and couldn’t drag on and on.

Create a Croak It profile, open the app, and do a test recording. It’s simple to use, and once you have the hang of it, you can fly through it with the students. My students like to do one final oral practice, then we record right after that.

After they have recorded their Croak It, title it with their name, and email the URL to yourself. I did this because I teach half day K, and I wanted to have a place to keep all their URLs just in case we didn’t have time to record and make the QR Codes in one day. Huge shocker, we didn’t have time. *detect the sarcasm*

The next day, we used the app “Zappy” to create our QR Codes.

Open the email containing the student’s URL.


Copy the URL by holding your finger down on the link and selecting “Copy”.


Open your QR Code creating app and select the URL option. This way when you scan the QR Code, it will lead you to the Croak It site containing your student’s recording.


Paste your URL in the text box by holding your finger down and selecting “Paste”.


After you tap “Go”, your QR Code will be created.


I imagine at this point, fancy people could print directly from here. However, for personal and professional reasons, I needed to make it look perfect. Therefore, I emailed the QR Code to myself by touching “Share” and doing just so. I also included the student’s name (big orange mark) in the email subject line to limit confusion.



I created a Word document of boxes with each of the students’ names and then inserted their QR Code into the proper box. Print, cut, glue on artist canvas, and presto. The codes are ready for anyone to scan. I included a few directions on the bulletin board so people would know what they are and how to use them.


They are beautifully hanging in the hallway. I took this picture with less than half of them completed, and they’re still fabulous.

    This is cool! Tokkers.com also offers a one-step method of recording and generating the QR Code on a computer. The recording is not currently available on iPads because there’s no Flash, but we’re working on an iOS app.

    Masterly crafted use of technology in the classroom – again, technology is not at the center. Students create and showcase. The visual and the audio are used with insight and the student still has pen in hand. The clever people explain the phenomena as “Blended Learning” Absolutely brilliant!
