I thought I would let everyone know how my first experience went with using QR Codes in the classroom.
Going in to the experience, I had several concerns:
1) Would the technology actually work?
2) Would students be prepared for class - would they have downloaded an appropriate app?
3) Would students use the app as intended, or would they just write down all the answers?
I tried this activity with my Geometry Honors class. I have three classes of Geometry Honors. These three classes are actually very different. One is made of almost all freshmen, one is made of almost all sophomores, and one is a mixture.
I am happy to report that the students in all three classes were prepared for class. Although not everyone has a smart phone, we had enough students with smart phones and an appropriate app that we could make plenty of small groups.
The technology worked fine! I was worried that perhaps our wireless wouldn't be able to handle that many requests at once, but it was fine. In fact, I guess I shouldn't have worried about it because in the activity I used, students didn't have to connect to wireless at all. The QR Codes I used led to text, so it wasn't a problem.
And, most of all, the students LOVED the QR codes. They loved being able to check their answers immediately. I am sure that part of it was it was a novelty...using their phones in math class - COOL! However, I think that the immediate feedback is a really great learning tool. The other interesting thing about it is that this activity worked best with my class that is the most squirrley (is that even a word? LOL)
After I had so much success with this activity the first day, I tried using QR Codes again the next day...I simply made a QR Code out of the answers to my students' homework. I had one student from each group come up and scan the code and then go over the answers with their group.
I am so looking forward to finding more uses for QR Codes in the math classroom.
