Many discussions about teaching introductory earth science focus on how to work with non-STEM majors but at a sizable number of institutions the majority, if not most students in an introductory class are STEM Majors (but not earth science majors), especially at institutions with significant engineering and agriculture programs. This roundtable serves as an opportunity for those teaching this audience to share their experiences and exchange strategies and ideas. This is especially valuable as at many places these other STEM Majors are big pool of potential (and actual) recruits into the earth sciences, but they enter with different capabilities to non-STEM majors (e.g. stronger math abilities).
