Evaluating the lines of evidence for plate tectonics part of Integrate:Workshops and Webinars:Teaching the Methods of Geoscience:Activities
In this in-class exercise, students compare several lines of evidence that support the ideas of continental drift and plate tectonics. Before the class meeting, each student is given a preparation assignment in which he/she studies one "continental drift" and one "ocean floor data" map. In class, students divide into teams of 3, with each team member having prepared different specialties. They discuss their respective maps and look for spatial patterns among the data.

Developing meaningful and manageable research opportunities for community college students: lessons learned from semester #1 part of SAGE 2YC:Workshops:Preparing Students in Two-year Colleges for Careers:Essays
Each semester, there are a handful of students in the science building every day working at the tables outside of the classrooms, dropping by office hours with hand samples, and asking questions after class related to, but beyond the scope of, the topic covered that day. They are the "repeat offenders" who have taken several courses in the department and are hungry for more. But when I say "more", I don't mean yet another rock identification lab or plate tectonics lecture...

Becca Walker: Using Surface Process Hazards in Physical Geology at Mt. San Antonio College part of 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.
