Social scientists have long worked to replicate real-world phenomena in their research and teaching environments. Unlike our biophysical science colleagues, we are faced with an area of study that is not governed by the laws of physics and other more predictable relationships. As a result, social scientists, and international studies scholars more specifically here, must make use of simulation and experimentation to study and replicate social phenomena. Growing out of the increasing use of simulation in the international studies field, the following symposium is an excellent collection of articles that demonstrate the diversity of approaches to the use of simulation in international studies scholarship and approaches to learning.
