Modern agriculture poses ecological problems and opportunities, which defy simple democratic reform without an educated citizenry. Developing an educated citizenry can be accomplished by further developing agricultural literacy in elementary education. While benchmarks for agricultural literacy have been produced, relatively little attention has been focused on how students conceptualize the food system. Using Piaget's theories of schemata development, this study compared students'

Students failed to convey an understanding of the types and variety of farms, the purpose of farms, or the cultural practices dominating conventional farming. Results suggest that educators should focus on existing underdeveloped schemata to help learners construct viable ideas about modern agriculture supported by contextually rich formal and informal agricultural experiences.
