Laura Rademacher: Environmental Science for Informed Citizens at University of the Pacific part of Integrate:Teaching for Sustainability:How the Community is Using InTeGrate Materials:Instructor Stories
My course is an introductory environmental science course. Over time, I've incorporated more opportunities for active learning in the classroom and students respond favorably to spending additional time on the topics they find most compelling. The incorporation of integrate modules has provided new opportunities for active learning in the classroom. Most of the modules lead students through case studies, many of which are focused on regions outside of California and those could broaden my students' perspectives on these issues.
