Here’s an interesting app – Wallitt – where the general idea is to post virtual messages on physical walls. I’m in the process of planning a Charles Dickens’ adventure at the end of the year with my students where I hope to use QR-tags, GPS location and smartphones.
The idea is to move the classroom outside and create a makeshift London in a nearby park where a local river acts the Thames. Spots along the local river will have GPS-locations and by using QR-codes, readers and their phones they will have to answer questions and learn about Dickens’ literature and life.
Wallit appears to lend itself to some good ideas as well. What about leaving virtual tasks outdoors in a city environment where students have to cooperate and solve them together.
