Once you get a hang of the process, creating QR codes to access student recordings is fairly straight forward and students can quickly learn to do it themselves. There are mays ways to use QR codes in the foreign language classroom.
One thing I like to do is make the codes available to parents so that they can listen to their kids speaking the language. For example, I made this bulletin board interactive so that the students voices can be heard reading their writing assignment. All it takes is a QR reading app on a smartphone to quickly and instantly hear the student’s voice.
Record on an app like Voice Record (available for free).
You can use Google drive to upload the audio files or Dropbox . Create a folder for the audio. Put the audio files into the folder.
Generate a QR link. Use http://www.qrstuff.com/
Paste the URL into the box and QR code will generate to the right. You can download the image or copy the image from the screen.
