QR Codes for Final Exam Review

Personal Phone

QR codes is a tool that allows someone to link an external link to a barcode-like image. Someone with a QR code scanner app on a mobile device or tablet can scan the QR code and investigate the link that pops up. My experience with QR codes was a great experience. At first, I could not find a way to get math problems such as volume of a cylinder or cone to adapt to the QR codes. QRstuff.com was a great resource to create my QR codes, but the DropBox link was a complicated one. The link to DropBox worked, but I was putting myself in the shoes of my students and noticed that they needed Adobe Reader in addition to installing the QR code scanner app. I knew I could make this an easier process for the students. After surfing the web for ideas, I finally found one. By creating my problems in PowerPoint and saving those problems as a JPEG, I could use PhotoBucket attached to the QR code.

This made the activity a smoother process for the students. In addition, the fact they were ALLOWED to use their phones (responsively, of course) engaged every student. The activity was basically a mini-scavenger hunt. The students started with the first QR code, which brought up a final exam review math problem. The answer to that question was somewhere on the front or back of the worksheet, which lead the student to his/her next problem to complete. I modeled the process just in case because some students had no idea what a QR code was. In addition, I make modifications for those students who didn't have the necessary resources by allowing a partner or using my cell phone.

In conclusion, I really enjoyed the practical use of the QR codes and I am spreading the idea among my colleagues. My school has a strict cell phone policy, but this is a great way to integrate technology.
