STELLA MODELING OF EARTH PROCESSES IN 9-12 EDUCATION

Traditionally, high school students learn about Earth systems in a static manner. Texts, videos and laboratory exercises generally lack the means to show the actual dynamic nature of Earth processes and interactive cycles. In contrast, teachers can now use computer modeling software and student manipulated data to understand the dynamic complexity of the Earth.

Scientists utilize models to study and understand complex systems. So too can educators use modeling concepts and scientific models to develop conceptual understanding of natural processes as dynamic and interacting. From the flow of energy and nutrients to the cause/effect occurrences and cycles, teachers can now use models to let students manipulate data that alters and simulates Earth processes. In this presentation, I examine how Stella software can be used to create student friendly models that help them better understand dynamic concepts and the relevance of data in the geosciences. I reference applicable learning goals as expressed in the National Science Education Standards, and California State Standards, as well as the tools and equipment needed to implement such instructional activities in high school science classrooms. Internet and other resources are likewise noted.
