Beat The Market ONLINE is an interactive set of simulation games and exercises for active learning & teaching of economics in a new and exciting way. For games or experiments, students compete making decisions for profit maximization utilizing economic concepts in different market structures. For simulation exercises (drills and practice) they learn by topic (such as law of demand, shifts in demand,elasticity of supply & demand, short-run & long-run cost, short-run & long-run production, market equilibrium, price elasticity, etc). The simulation motivates students to learn, makes economics relevant and improves critical thinking skills. All games and exercises are automatically graded, with an online Gradebook. An online tutor acts as a consultant and helps guide students. Ideal to support lectures and presentations. Students compete in teams or individually, against each other (multi-player games) or computer managed firms (single player games). It has "learning levels" which the Instructor selects to make the games simple or complex. Therefore it is used at the High School and College levels for Introduction to Economics, Principles of Microeconomics, Managerial Economics, Intermediate Economics and MBA economics and as a business management simulation.
