Information presented in greenhouse management courses has changed in response to several factors. Increasingly, students must learn about:
new technologies such as the use of computers in crop management, and new techniques such as implementation of biological pest management;
regulations like the EPA/OSHA chemical safety laws;
experimental procedures, to be able to assess future technologies and techniques during their careers; and
professionalism (industry leadership, ability to work with the media, knowledge of how to impact law).
Changes in course content and procedures over time, and methods of teaching increased types and amounts of information, are discussed through results of a survey of current instructors of greenhouse management courses.
