Waiting for the bulldozer: Barcelona in decline
One of my favourite blogs (and RSS feeds), Boing Boing, brought me this Time.com photographic essay of Detroit's Beautiful, Horrible Decline by French photographers Yves Marchand and Romain Meffre [ >> website, for more images].
You don't have to live in a city like Detroit to see ruined buildings (see image above, of Barcelona) and getting your students to photograph them (or construction sites or graffiti…) might make a great project which they could share via a blog.
Those less gifted with a camera, or interested in photography, could participate in the design of the blog, the writing of accompanying text, etc. If your learners have to either take pictures or write the text, they have to interact and communicate.
As I suggested in a recent workshop, one of the attractive things about such a project is the opportunities it affords for real language use to take place: you are setting up enjoyable, creative, real tasks, not fake role play.
