Peer Teaching Increases Knowledge and Changes Perceptions about Genetically Modified Crops in Non-Science Major Undergraduates.

ABSTRACT: We analyzed effects of peer teaching on non-science major undergraduates' knowledge, perceptions, and opinions about genetically modified (GM) crops and their use in agriculture. Undergraduates enrolled in an introductory nonmajors biology course participated in a service-learning program (SLP) in which they acted as cross-age peer teachers to high school students, teaching about the role of genetics in crop improvement through traditional breeding and GM approaches. Using pre/postassessments, we found that undergraduates' opinions shifted to favor the use of GM organisms (GMOs) in agriculture after SLP participation, rising from 46 to 97%. Perceptions about risks and benefits of GMOs also shifted from 43% stating that GMOs are harmful or suspect to no students describing GMOs in that way.
