Editors' Introduction: Simulations and games for transition and change in lifelong learning: Danny Saunders and Nina Smalley

The theme of this year's International Simulation and Gaming Research Yearbook is that of transition and change. We apologize at the outset to readers who have expertise in semantics and who will notice that the use of transition and change concepts can also be used interchangeably, given their respective dictionary definitions as nouns and adjectives. However, we find the current distinction to be useful for the analysis of educational developments at the beginning of the 21st century.
