1) QR Codes to My Flipped Classroom Google Forms.
For flipping my class, I supply my students with a guided note sheet to complete with the video. Before QR codes the students had to navigate to my website, but now they can scan the QR code on the notes and it will bring them right to the Google Form with the video and questions.
2) QR Codes to Answer Keys for Homework.
I like for my students to have access to the answer keys while they complete their homework to check their work. However many students did not want to take the time to navigate to my webpage to find the keys. Instead I create a QR code and put that on their homework so when they are done they can scan the code and check their answers right away.
3) QR Code For a Bell Ringer
As soon as the students walk in the door to my classroom I want them to be engaged so I have them fill out a Google Form several times a week to see what they thought of the homework. Instead of giving them a URL, I project a QR Code linked to a Google Form on the front board. They then scan the QR code and they have a few minutes to complete it while I check their homework. I find that this is a great time for me to check their homework instead of wasting time during class to do it. It also gives us a chance to look at the responses and discuss them as a class.
