Conversion of the introductory plant biology course for non-majors from a lecture/lab format to a web-based course was a collaborative project between the Department of Plant Biology and the Instructional Support group at ASU. This course provides an introduction to biology through the world of plants by including lectures and laboratory activities that examine plant systems. The project was undertaken to provide students with an asynchronous opportunity to participate in either the course, the lab, or both. There were three distinct phases of implementation of the multimedia website: Design, Development, and Delivery. The design phase was driven by the faculty, who, along with graduate assistants, developed the course outline and content. They gathered images, identified concepts to be animated, and created storyboards to layout the sequence in the animation. The development stage was driven by the Instructional Designers who selected the appropriate media for animations and worked with developers to create them. The delivery phase was again driven by the professors. They implemented the website as a teaching tool, gathered feedback from students and teaching assistants, and worked with instructional designers and multimedia developers to improve the site. A wide variety of on-line multimedia components were incorporated into the website, including illustrations, images, animations, interactive modules, video and text. Three separate media packages were used: MacroMedia Flash (Macromedia, 2000), Director Shockwave (Macromedia, 2000), and QuickTime (Apple, Inc. 2000). Findings from surveys of students, faculty, and staff identified positive regard for the site as a whole. Several technological and logistical challenges were encountered and addressed.

Because ASHS has adopted in their editorial policies the use of Systeme International (SI) units, it has become necessary to report light measurements in units other than footcandles. Since measurements using a radiometer can be tedious, tables providing values for different sources of light are often used to approximate required units. Using the tables provided by Thimijan and Heins [HortScience 18(6): 818-822], a Lotus 123 worksheet program was designed to interconvert photometric, radiometric, and quantum light units of measure. The worksheet is menu driven and can handle straight conversions or mixed conversions by entering requested information. Setup of the worksheet and instructions in its use will be provided at the meeting.

As the public becomes more aware of environmental concerns, there has been a renewed interest in composting. Municipalities are promoting composting as a way to save diminishing landfill space. Although there are many successful composting programs, many would-be composters are thwarted by a lack of expertise, information, and follow-up support. Brochures, videos, and slide presentations present visual information, but hands-on instruction and active involvement in on-going programs has increased the likelihood of success. Integrating composting into established programs, such as community gardens, institutional programs, education curriculum, and demonstration sites, has proven an effective method of conveying composting information to the public.

Horticulture Teaching Resources is a web site at The Ohio State Univ. designed to provide high school and higher education horticulture educators free-access to curriculum resource materials. The information has been structured to facilitate the instruction of basic concepts in plant biology, propagation, nutrition, and plant materials. A searchable database interface is used to access color photos, lab exercises, and test questions. Users of the system can also provide URL addresses to their own resources for inclusion in the database. (

The Teaching Portfolio is a factual description of a professor's strengths and accomplishments. It includes documents and materials that collectively suggest the scope and quality of a professor's teaching performance. The Teaching Portfolio is a living, breathing document that changes over time. Items in a Teaching Portfolio include a statement of teaching responsibilities, description of steps to improve teaching, instructional innovations, student and teaching evaluations, awards and honors, and a record of students who have succeeded. I will discuss the steps taken at Clemson University to use the Teaching Portfolio.

The University of Florida College of Agriculture and Life Sciences offers the Bachelor of Science degree program in Environmental Horticulture at the Fort Lauderdale Research and Education Center (FLREC). Instructors at the FLREC deliver course work and course work is also presented using a variety of distance education (DE) technologies. These DE technologies include interactive video conferencing, videotape, and web-based courses. The question often arises as to how many courses should be delivered using DE versus live onsite instruction. This survey was conducted to ascertain how students perceive the quality of education they are receiving using a mixture of delivery methods.

A flat bed scanner can be used as a high-resolution digital camera with close-up capabitlities for photographing plant material such as leaves, flowers, and plant pests. The scanner is very useful as a diagnostic and instructional tool that is more portable and less expensive than a camera and dissecting microscope. The quality of the images can be very good and can be enhanced in post-production using image editing software. The main disadvantage is the shallow depth of field, which requires the object be on a single plane.

A library skills workbook was developed for horticulture students to provide them with instruction in the use of bibliographic research materials and services available to them from the university library system. The effectiveness of the library skills workbook was tested by comparing pre- and post-test scores of undergraduate and graduate students. International and national graduate students were compared. Graduate students scored higher on the pre-test than did undergraduates. Students from the United States scored higher than Asian students, but not higher than Latin American students. Students' knowledge of the library collection and layout were improved 21.3%; however, undergraduate students' knowledge increased 13% more than that of graduate students.
