PRESENTATION ASSIGNMENTS

Review of Disease Management Web Sites

The purposes of this assignment are to learn about disease management resources available on the World Wide Web, and to learn to review resources critically for content, organization, and presentation. Students will work in teams of three or four. Each group will identify a theme of choice and review at least three web sties to critique orally. Initially, students will work together informally as a team to1) identify the theme and 2) to define the strategy for critiquing the sites. For example, themes might include integrated disease management, emerging or re-emerging diseases, diagnosis and control recommendations for a specific disease, disease forecasting, etc. Factors to consider in the oral critique would include overall organization, style of presentations, usefulness and accuracy of content, quality and appropriateness of graphics, and amount of information. For the oral presentation, each member of the team is responsible for presenting one part of the review

Disease Management Lessons

The objective of this assignment is to create a lesson of a plant disease common to the Pacific Northwest . The target audience for the lesson could be a commercial grower, extension agent, consultant, organic farmer, home gardener, pesticide applicator, etc. The lesson should emphasize disease management recommendations and needs to be a visual product suitable for incorporation into a Web site. Examples of disease lessons can be found at www.apsnet.org/education/top.html under Introductory Plant Pathology. Lessons already posted on this web site are not acceptable as a lesson for this class (see below). Please okay your topic with one of the instructors.
