An Experimental Test of a Visual Learning tool for Plant Identification.

Learning to identify plants is extraordinarily difficult, yet field botanists can quickly and easily make identifications at a glance. They do this without recourse to the use of traditional characters or keys. Achieving this type of recognition accuracy is a central goal of many courses in plant systematics and field botany. Teaching plant identification is difficult because of variability in the plants’ appearance, the difficult of bringing them into the classroom, and because it is often difficult to take students to the field, especially on urban campuses. To solve these problems, we developed and tested a cognitive psychology-based computer program to teach plant identification. The program incorporates presentation of plant images in a homework-based, active-learning format that was developed to stimulate expert-level visual recognition. A controlled experimental test against traditional study methods was performed in the context of a college course in plant systematics. Use of the program resulted in an 8-24% improvement in final exam scores, depending on the type of identification question used (living plants, photographs, written descriptions). The software demonstrates how the use of interleaved examples, spaced repetition, and retrieval practice (SPRINT) can be used to train identification of complex and highly variable objects.
