Learning about Dynamic Problems with Computer Simulators: A Case of System Dynamics Simulation Models

A vast body of research shows that people by and large fail to understand and manage dynamic environments. Given the increasing complexity of our world, there is an urgent need to develop more effective ways to present dynamic problems. Many studies propose computer simulators as virtual learning environments to help people understand and manage complex problems. Still, experimental data show that simulators often carry problems from reality into the virtual laboratory. An analysis from the perspective of cognitive load theory suggests that learning about complex problems could be improved by enhancing descriptions with simulation elements that would facilitate interactive exploration of the problem dynamics. We develop such an applet, featuring dynamics generated by a non-linear accumulation rate and review experimental results testing its effectiveness.
