Systems Thinking Experiential Learning Laboratory with Animation!
Icon based dynamic simulation modeling software
How is it useful?
Context for simultaneously building conceptual & mathematical model that responds to:
Internal structure of the system
External forces (“forcing functions”) acting on the system
Tool for the practice/philosophy/worldview of “systems thinking”
Model of water in a reservoir
Dynamic simulation model/tour of STELLA
Practice thinking in stocks and flows
Stock = state variable:
Amount of stuff stored in various parts of a system
Flow = input & output = rate of change = differential equation:
The movement of stuff into or out of a stock
