With the use of classroom simulations, theory and field research can be synthesized, thus bringing both theory and research into an "action" form for the education student. Interactive computer systems allow for active involvement and immediate feedback. One classroom simulation, already constructed, is described. For this simulation a conceptualization of classroom discourse was used for the design, with the participant choosing an objective for the lesson to be "taught," selecting a teaching strategy, and hence designating individual moves. Also described are the development of the program, simulation evaluation, and suggested further work in simulations. (JA)
