A Critical Survey of Environmental Content in United States Undergraduate Mechanical Engineering Curricula

This survey examines how mechanical engineers are being prepared to be responsible stewards of the environment by offering a multi-channeled look at a diverse collection of twelve US colleges and universities, with connections to the larger global context. This study enumerates the external influences of professional organizations, those responsible for program accreditation (Accreditation Board for Engineering and Technology (ABET)), professional conduct (American Society of Mechanical Engineers), and licensure (National Council of Examiners for Engineering and Surveying, National Society of Professional Engineers). At the curricular level, this study presents current mechanical engineering curricula via core courses (required at most institutions) and non-core courses (required at a minority of institutions or elective courses). The curriculum study identifies fifteen core courses and uses the Open Syllabus Project and online bookstores to identify a representative textbook and classify the environmental content therein. Immediate results show the environment receiving sparse treatment in core course textbooks, institutions having zero environment-focused degree requirements, and a tendency towards offering electives that are narrowly focused on green technologies. Elective offerings mirror ABET’s recent move away from emphasizing the “broad education necessary to understand the impact” of engineering solutions to instead “consider the impact of” engineering solutions in an environmental context. Overall, the environmental education mechanical engineers are receiving is insufficient in amount and lacking in scientific and ethical foundation. Ideally, every mechanical engineering program should include coordinated environmental content throughout the curriculum and require at least one course that teaches both environmental design principles and the importance of environmental stewardship. A novel approach eschews the typical artes mechanicae course structure to teach environmental stewardship in the artes liberales educational tradition, emphasizing multi-dimensional thinking by employing great books style discussions of seminal scientific, ethical, and technological works.
