The world is full of systems. Often they exist below the threshold of what we perceive. It's all a whirling clockwork of near-infinite complexity, from the tiny mysteries of quantum physics to the wonder of a single tree spanning miles, to the vastness of neurons that sit inside our relatively small skulls. 

PAXsims is devoted to the discussion of conflict simulations and serious games that address issues of security, development, and peacebuilding for educational, training, and policy purposes.

There are several simple card game based economic simulations within this collection

an International Relations Simulation designed for both large and small classes with 11 years of in class testing and refining by Dr. Keller of James Madison University. Statecraft puts students in a world where they will engage in trade, war, spying, two level games, and diplomacy throughout the semester.

seven larger ideas for motivating and engaging people on the basis of observing many games' stunning power as engines of human engagement:

Lot's of research and "how to's" about active learning.

Children love to learn, but at some point they lose that and become adults that don't like formal learning. Let's explore why "play" has gotten such a bad rap and figure out how to get it back in education.

Camp and child focused. But could easily be adapted for organizational training. Many many ideas, some broken links.

How could magic inform learning?

Abstract We developed a conceptual tool intended to help teachers make a good start in using digital games in the classroom. The tool is a matrix of questions based on a literature search and an empirical study with teachers. Its primary aim is to foster self-reflection and communication with other practitioners or designers. It was produced in the context of the GEL Theme Team of the STELLAR European Network of Excellence.
