This guide is designed to assist business teachers to effectively use simulations that involve student interaction. Learning experiences in all levels of business and office education are examined: business exploration, basic business, and occupational preparation. In the introduction, the types of simulated activities are explained, along with their use. The guide is divided into two major sections: simulation games and model office simulations. In the Simulation Games section, the value of these games is discussed. Also, the ways in which to select, use, adapt, develop, and evaluate simulation games are considered. A selected bibliography of books and articles on simulation games and descriptions of simulation games (containing source, subject, grade level, playing time, number of participants, cost, and game description) are included. In the Model Office Simulations section, flow-of-work competencies are explained. The selection, use, development, and evaluation of these simulations are examined. The model office facility area contains basic guides to follow in designing a modern office and several suggested layouts. A selected bibliography of articles describing unpublished model office simulations include the type of business, suggested occupational positions, data or transaction input, equipment needed, forms provided, duration of the simulation, source, and author.
