The fine blog The Tech Savvy Educator recently posted about an excellent online game on environmental issues called Planet Green Game. He describes it quite well in his post, so I won’t go into many details here. It’s basically a role-playing game where players have to minimize their carbon emissions. And it’s combined with learning environmental facts.
I didn’t spend a whole lot of time playing it, but I was especially impressed that there’s audio support for a fair amount of the text. Of course, that makes it particularly accessible to English Language Learners, though I’d say it’s complicated enough so that just Intermediates or Advanced students should play it.
I’ve placed the links in a few areas of my website, including under Toward The Twenty-First Century.
