A publicly accessible multimedia instrument for greenhouse education was developed for global use. The instrument consists of (1) greenhouse videos produced on site in Arizona. Vermont. Ohio and Florida that emphasize state-specific production, environmental control, labor, and marketing issues; (2) an interactive Flash-based greenhouse environment simulator that allows users to model greenhouse environments based on climate data from each of the four video locations; (3) a searchable digital repository containing hundreds of useful greenhouse images, videos, and lectures, and (4) a web-based method for instructors to evaluate perceived student learning of greenhouse concepts. The Interactive Greenhouse Environment Simulator is driven bv a mathematical model developed bv engineers which is linked to a Flash-based graphical user interface (GUI). Following user selection of climate, structure and environmental control choices, dynamic environmental information is shown graphically during the simulation, allowing users to model changes in the greenhouse environment.
