The basic premise is this: the teacher links up with another class (organized via https://education.skype.com). The class "meets" at a previously designated time, taking turns asking each other yes/no questions in order to narrow down the location of the other class. The students all have jobs, and after a few practice runs, it all runs like a fairly well-oiled machine.
I've noticed an increase in students' ability to ask more and more effective questions. They learn not to ask about a specific state until they know the time zone, relevance to the Mississippi River, etc. They learn to work together, utilizing a blend of digital and print sources.
My kiddos still switch jobs here and there, hoping to find the right fit. It is truly the embodiment of student-led and directed learning! (Hellooooo evaluation!)
Here is some photographic evidence of fun:
My Logical Reasoners, busy reasoning and goofing, apparently.
