QR (quick response) codes are basically special bar codes that can be read by smart phones and tablets. First, you download and install QR code reader software (some phones have it pre-installed). Then, when you see a QR code, you load the software and point your device’s camera at the code.
Data–usually text, a form, or url–will appear on your screen. I am hoping that if your parents allow you to use your phones for educational purposes in the classroom, we can try out some of these exciting QR code ideas. The codes are easy to create. However, as with all internet tools, precautions and safety must constantly be at the forefront of our minds when scanning and creating QR codes. Only point to codes from sources you, your parents, and teachers trust–such as those in magazines, newspapers, museum exhibits, and on reputable websites. Beware of randomly posted QR codes. There is no telling where they may lead–possibly to inappropriate websites or to viruses and hacks. People who include full names, addresses, phone numbers, or other identifying information when creating their own codes put themselves at risk of receiving unwanted contact or attention.
This blog post discusses QR codes at length and includes a video demonstration. If you already have a QR code reader loaded, try scanning the above code. It will link you to the same place! -Ms. T.
