Becca Walker: Using Surface Process Hazards in Physical Geology at Mt. San Antonio College part of GETSI:Teaching Materials:Surface Process Hazards
I teach a physical geology class with a diverse group of students with respect to academic background and major. We spend the majority of the semester working with rock and mineral identification, maps, and tectonics, but I wanted to incorporate more of a societal component into this particular course. The surface processes hazards module gave me the opportunity to help students consider the intersection between geologic phenomena and humans. My students seemed to enjoy working with such a variety of maps and study areas. The collaborative nature of identifying landscape features and ranking areas' mass wasting susceptibility was a great opportunity for interaction, debate, and synthesis of a variety of data sets. They were quite engaged as they put their maps together for the Boulder Creek case study. The incorporation of human modification of the landscape and the implications for mass wasting vulnerability got them thinking about their own neighborhoods in southern California.
