Dichotomous Keys can be replaced with Computer Based Expert Systems, but these Systems need Experts trained in the Subject Matter and Computer Technology for their Creation.

To meet this need the following OBJECTIVES

were set forth:

Enrich the educational experience of students by involving them in the creation of a CD-ROM Dendrology Expert System that would replace dichotomous keys (DK ) that are currently used in Plant Identification courses.

Improve instructional effectiveness by engaging undergraduates in the creation of this expert system which will require utilization of their newly/simultaneously acquired knowledge of trees and wood into a format that is both self reinforcing and beneficial to future students.

Test the effectiveness of this method of learning compared to current pedagogic practices.
