Economics and logistics have greatly reduced or eliminated the ability of horticulture instructors to use field trips or on-site visits as educational tools. This is especially problematic in the field of greenhouse management and controlled environment agriculture, since the facilities and technologies used are essential to the discipline. To address this problem, we developed 15 DVD-based virtual field trips (VFT's) that instructors may use to demonstrate to students the most up-to-date facilities, technologies, and management strategies used in greenhouse management (ornamental and food crops) and controlled environment agriculture (GCEA). Each VFT included a preface with background information about the company, a tour organized by subject chapters, self-examination, and a teacher's guide with additional information and case studies. Each land-grant institution with an instructional program in greenhouse management of controlled-environment agriculture will be provided a free copy of each VFT, which will benefit all instructors of GCEA in the United States.

ePortfolios are gaining popularity in academic communities worldwide. Purposes of ePortfolios include: converting student work from paper to digital format, thereby allowing it to be centrally organized, searchable, and transportable throughout their academic lives and careers; promoting student centered learning and reflection; improving advising; and career planning and resume building. Pennsylvania State University is investing in the use of ePortfolios in course work throughout the university system. To facilitate these efforts, the university provides all students and faculty with 500 MB of hosted web space to create and share their portfolios. One of the courses using ePortfolios is Horticulture 120, Computer Applications for Landscape Contracting, in the Landscape Contracting program. Outcomes of implementing ePortfolios include increased availability of student work to potential employers, enhanced recruiting through displays of student work, and enabled reflection on completed work. Students showed improved quality in project work because their projects would be publicly available through the Internet to potential employers, faculty, family, and other students.

Currently, in the United States, the greenhouse industry covers more than 15,000 acres and is supported by a diverse number of firms with employee expertise that includes greenhouse manufacturing, engineering, irrigation, horticulture, IPM, sales, marketing, and business management. The growing greenhouse industry continues to be in need of highly trained undergraduates that have mastered an amalgam of scientific and business concepts necessary to be competitive in today's agricultural marketplace. Using a multidisciplinary approach we are creating a multimedia instrument for utilization in a variety of greenhouse related courses. This instrument ultimately will be available on the web for anyone to access. To ensure that our vision matches need, we have reviewed the courses offered throughout the United States at 1862, 1890, and 1994 land grant institutions. Course information collected includes; college, Dept., title, level, description, website (if available) and instructor e-mail (if available). Interestingly, there are at least 84 courses offering some aspect of greenhouse science in the U.S. Most are offered in Colleges of Agriculture or Engineering, but are housed in 17 diverse Dept.s. Examples include Dept.s of Horticulture; Agronomy and Horticulture; Agricultural Biosystems and Engineering; Plant, Soil, and Entomological Science; and Horticulture, Forestry, Landscape & Parks. This information will be utilized to focus the instructional design phase of the multimedia instrument, to contact current course instructors for feedback, and to frame future development of the resource.

The Mississippi (MS) Greenhouse Tomato Short Course has been held every March since 1989. The purpose of this 2-day, intensive training is to educate growers so they will be able to successfully grow greenhouse tomatoes as a viable horticultural business. With a mixture of experienced, novice, and prospective growers, it is just as important to provide current growers with research based, practical information, as to expose potential growers to the realities of the business, helping them make an informed decision before investing time and money. Beginning as a small program for a handful growers in the conference room at the Truck Crops Experiment Station, it has gradually grown in number and diversity of participants and invited speakers, depth of subject matter, and geographic origin of growers and speakers. The 2003 program had 142 participants from over 20 states and 4 countries, making it the largest such program in the United States. This is in keeping with the recent trend. The typical lineup of topics includes the basics of producing a commercial crop of hydroponic greenhouse tomatoes, the budget for establishing and operating a greenhouse business, marketing and promotion, pest and disease identification and management, and the grower's point of view. Other topics, varying year to year, include heating, cooling, and ventilation of greenhouses, record keeping, new technologies, biological control, diagnostics, and alternative crops. For 2004, the subject of organic production will be introduced. With targeted extension programming such as this Short Course, the greenhouse tomato industry in MS has grown from 15 growers in 1989 to 135 growers today, producing $6.5 million in annual gross sales.

Research indicates that humor is an effective method to reinforce learning, yet humor is rarely used in horticultural textbooks. Use of humor in horticulture is easier than in many disciplines because humor dealing with plants is less likely to offend specific population segments since plants, not people, are usually the butt of the jokes. A large collection of plant humor has been assembled, including the following: Edward Lear's 32 line drawings of “Nonsense Botany”, e.g. Manypeeplia upsidonia; Gary Larson's macabre Far Side cartoons dealing with plants, e.g. the “Venus kidtrap”; periodic tables of vegetables and of fruits & nuts; Arcimboldo's Renaissance paintings of faces composed of flowers, vegetables, and plant parts and their modern imitations; Robert Wood's book, How to Tell the Birds From The Flowers, containing drawings and poems; Axel Erlandson's fantasticly grafted trees; plant movies like the two versions of Little Shop of Horrors, which is set in a flower shop; Joke Fountains of the Renaissance; and numerous cartoons from science periodicals.

To improve the communication skills of students studying horticulture, collaboration between the subject lecturers and an academic skills consultant has led to the inclusion of a writing portfolio into the curriculum of Plant Science and Physiology, a core science component of the Bachelor of Horticultural Science program. The rationale for the portfolio was that, through writing, students would engage more closely with a subject's content and would gain a better understanding of its concepts. The initiatives introduced into the portfolio include the development of nine writing portfolio tasks and model answers, an appropriate grading tool and the integration of the writing tasks into other assessment tools. The focus on writing simultaneously improved students' awareness of the standard and type of writing expected at university, allowed them to develop their written expression, and deepened their understanding of plant science.
