The Disease Triangle As A Learning Object


The disease triangle concept is often used in teaching both plant disease development and the significance of plant diseases in the environment. The plant disease triangle is rarely studied in a curriculum outside of plant pathology. This module presents an oppurtunity for students to study this subject and develop an awareness of the importance of plant diseases in civilization and modern society. Not only does this module bring together an understanding of the disease triangle, but it also examines closely associated elements and events related to the process of disease development and epidemics. Those viewing this module will be presented with concepts, an activity, and an assessment for each of three proficiency levels of the learning object to ensure that important points were understood. Instructors are encouraged to use this module as a supplement to further emphasize points covered in their courses.
