In 1967, the Northwest Regional Educational Laboratory sponsored a one-week workshop for 32 teachers from a semi-rural county, and a one-day workshop for 500 teachers from the same county, for the purpose of instructing the teachers in the use of simulation techniques for more effective classroom teaching. Several of those in attendance went on to obtain advanced degrees in the use of game theory, while others have created their own games for classroom use. This paper presents a sample game called "Teacher Preparation", underlining the tasks which the game hopes to accomplish. They include: (a) development of an undergraduate college program for teacher candidates that specifies course experiences and contents; (b) restatement of problems into challenges; (c) keeping in mind the reality demons that push ideas into conformity with actuality. (Each representative and reality demon role is described in attachments.) Procedures for playing the game are also outlined. (Author/CJ)
