Graph 1: Geoscience department total student semester credit hours (SSCH) over trailing 10 year period. This represents the number of teaching hours by GEOS faculty, instructors, adjuncts, etc. for full academic years. It is strongly influenced by low-level, high enrollment courses like General Geology and Human Geography. For example, if GEOS teaches General Geology lecture/lab (4 hrs) with 600 students, this would add 4 x 600 = 2400 SSCH to the GEOS total. In the long run, GEOS teaching assistantship count assigned by the College responds to SSCH numbers.
