The philosophy of the Science, Technology, and Society (STS) model is illustrated in this planned course outline on a thematic unit on corn. Parts of the lesson include the instructional objectives, instructional strategies, projects, and evaluation. Students will learn about the role of corn as a source of energy, the importance of crop yield and its impact on society, and ecological aspects such as the farming of corn. Instructional strategies include group work, class discussions, concept mapping, and video productions. Evaluative techniques focus on analytic and holistic rubrics. The rubric checklists (STS concept map rubric, STS time line rubric, and STS video production rubric) contained in the lesson focus on the STS philosophy and are representative assessment tools for projects listed in the lesson.
