QR Droid is my favorite free QR code reader for Android devices. QR Droid website offers a free QR code generator that makes it very easy to create a QR code for just about anything. This weekend I installed a free plug-in for QR Droid called QR-GPS Plugin.
QR-GPS Plugin works with the free QR Droid app to allow you to quickly create QR codes for the GPS coordinates for wherever you are standing. You ca also manually input coordinates or manually input a location by entering an address. Whichever way you choose to input locations, the QR code that is generated for you can be shared via text message, email, Twitter, or Facebook. You can also save the code to your SD card and print it. (Of course, if you emailed the QR code to yourself you could print it from there too).
When you scan the QR code generated by QR-GPS Plugin you can open it within a number of different Android apps including Google Earth, Google Maps, Â andÂ GPS Essentials. The QR Droid blog has detailed directions on how to use the QR-GPS Plugin.
For academic activities using the QR codes generated from QR-GPS Plugin, I have a few thoughts (with a little help from a friend). Â First, since the codes easily open in Google Earth and Google Maps you could create geography puzzles in which students use clues to guess the location to which you’re leading them. Then to check their answers students scan the QR codes and open them in Google Earth or Google Maps on their tablets or phones. Second, create a scavenger hunt in which students go from location to location scanning QR codes to get directions to the next stop in the hunt. Finally, the QR codes could be scanned and saved in Google Maps or GPS essentials for students to use as part of a walking tour.
