Science and Sustainability: A Freshman Seminar Course
Steven Neshyba, University of Puget Sound
The backbone of the course is made of two books: Berger and Luckmann's The Social Construction of Reality and Pollan's The Omnivore's Dilemma. Students will discuss these readings in a seminar format, write papers, take exams, carry out a chemistry experiment using mass spectroscopy, and undertake a research project into current pedagogical approaches to science and sustainability.
