DEVELOPING ECOLOGICAL THINKING IN FRESHWATER SYSTEMS IN INTEGRATED INTRODUCTORY BIOLOGY AND CHEMISTRY COURSES FOR FRESHMEN LIFE SCIENCE MAJORS
Developing ecological thinking in freshmen undergraduate students is a daunting task. Vision and Change (2011) made calls for undergraduates to learn science as a process and use quantitative reasoning in interdisciplinary ways but challenges to curriculum development that supports these notions persist. In response to this and other national calls, the University of Delaware developed a unique program for freshmen life science majors that integrates both introductory biology and introductory chemistry and provides students the support to develop needed skills through active learning methods. Here I present a six-week lecture, laboratory, and studio module that helps students integrate both biological and chemical concepts using lotic ecosystems as a model. Students authentically explore water quality issues within the State of Delaware and ecological concepts like spatial and temporal patterns of biogeochemical cycling and community interactions. Students develop observation skills by first exploring aquarium mesocosms followed by collecting field samples on UD's campus and subsequent laboratory analysis. They finally present self-designed research questions through posters. While structure is in place for learning to occur, assessments need to be developed still to better analyze learning gains.
