This
paper addresses ongoing research into visualization of system
dynamics models to help the understanding of complex systems.
The paper discusses a prototype under development named "The
Two-Shower Model". This collaborative interactive learning
environment presents learners with a seemingly simple task: to
reach a pleasant temperature in two showers that share the same
hot water resource. This is however an example of a complex nonlinear
system that may be difficult to control. Both particpants must
reach an understanding of how the system works in order to be
able to control it together. The paper discusses how visualizations
may assist the participants in that process.
