As I said earlier, the participants have to show how they found their answers. This information is collected into an archive that is available to everyone. In short, the Hunt is a Community of Practice. In this case, I figured that forcing both Holmenkollen and Trosterud with plus signs I would quickly find out where they were. The Hunt's participants learn by Legitimate Peripheral Participation in a Community of Practice.
New participants learn from the experiences of the old.
As new participants gain experience, they pass their own experiences on to newer participants through the Hunt's archives. The role of the teacher in the Squirrel Hunt is to ask the questions that start the students on journeys of personal discovery. On the surface, this appears to violate Wenger's requirement that there be a genuine situation of experience, but this isn't entirely so. In situated learning you try to move to mastery of the practice. While the act of the teacher asking questions borders on being instructionist, it is the end result that is important.
