Practical Applications of Systems Thinking and STELLA in the High School Setting Presented by: Jeremy Merritt, Mark Clemente VSTE 2009
What is a system? “A system is an interconnected set of elements that is coherently organized in a way that achieves something” Donella H. Meadows, Thinking in Systems: A Primer (Chelsea Green Publishing, 2008) 11

Stocks & Flows The bathtub is a stock
Stocks & Flows The faucet and the drain are flows
Modeling Systems with STELLA
Other Stocks & Flows Same thing, different units
Feedback Loops A feedback loop occurs when a stock affects its flows R
Feedback Loops Reinforcing Loops R R R
Behavior vs. Data It’s important to focus on behavior when you’re thinking about systems R
Feedback Loops Balancing Loop

Applying Systems Thinking in the Classroom Use Systems Thinking Stock & flow Mapping Use Model-based Concepts Materials Non-software-based Software-based
Earth Systems Science & STELLA An example: GLOBE Carbon Cycle Program Bringing cutting edge research & techniques into the classroom STELLA models that use input data collected by students and researchers Focus on using technology & modeling to give students an understanding of local and global carbon cycles
Lessons in Mathematics Lessons in Mathematics: A Dynamic Approach by Diana Fisher provides a set of materials that can be used to supplement current curriculum for Algebra I, Algebra II, Pre-Calculus and Calculus classes.
