Abstract:
Web based Blackboard® and CD images of selected crops were developed for the plant identification module of an introductory freshman level crop science lab to supplement existing live plant and seed materials, and to increase access to students. Over three years, students in three classes (n=48) were surveyed on their usage and perceptions of these four aids when allowed to select any of them. Most (62%)used all the available combinations of aids. Students used the seeds twice as much as any of the other aids. Although students reported good satisfaction with all four aids, they found the seeds and live plant materials most useful. The number of study aids used was somewhat positively correlated with student test scores and overall frequency of their use (r= 0.38,p=0.01, r=0.35 p=0.05). This study indicates that students' tendency to use all available study aids of live materials and computer aids was beneficial in learning crop identification.
