Commodities are a class of goods that can be produced in such a way that it is difficult or impossible to distinguish one instance of the commodity from another. The price of the commodity is determined as a function of the market as a whole, not in regard to who produced it or how it was produced. Commodities share a common problem in that prices and production exhibit repeating cycles. This simulation introduces students to the concept of commodity cycles by comparing two types of hog
farms:
• Large; over 2000 hogs produced per year and primarily serving the price-conscience consumer
• Small; fewer than 2000 hogs per year and primarily serving the quality-conscience consumer.
Complex Systems Connection: Cause within System. Five interdisciplinary areas are covered in a series of lessons, utilizing a family of models that all generate oscillation. Oscillation in real-world systems is often considered problematic rather than a consequence of system structure. This progression of lessons will help students understand that undesirable behavior can be a consequence of system structure and not a result of outside, uncontrollable influences. In other words, a system that oscillates does so because it has an inherent tendency to do so. |

This lesson explores a commodity market, hog farming, periods
from two different perspectives. Students experience a simulated large and small farm, comparing the similarities and differences among trends, including retail pork prices and availability of pork.

This model illustrates how a commodity often oscillates over time based on supply, demand, and price. Students explore a pork commodity, comparing simulation results given two scenarios for large and small farms.

Led by a partnership between MIT Professor Emeritus Jay W. Forrester and the Creative Learning Exchange, the goal of the Characteristics of Complex Systems Project is to create online curricula for ages five and above that will illustrate the characteristics of complex systems. In exploring the nature of complex social systems, the curricula address questions such as – why do such systems resist policy changes? Why are short-term and long-term responses to corrective action often at odds with each other? How can leverage points be applied to bring about desirable change in social systems?
The goals of the project are grounded in the belief that an abstract level of understanding of social systems will help prepare future citizens to actively shape their society.
The lessons and simulations are based upon the fourth characteristic of complex systems: the cause of the problem is within the system.

| Teaching Characteristics of Complex Systems in K-12 Education: Lessons Learned |

This paper describes lessons learned while completing a pilot project initiated by Professor Jay Forrester through the Creative Learning Exchange. The goal of the Characteristics of Complex Systems Project (CCSP) is to create online curriculum materials for K-12 students and interested adults that will illustrate the characteristics of complex systems first enunciated by Forrester (1969) and appearing repeatedly in the systems thinking/system dynamics literature since then. The pilot project was designed to address the characteristic “The cause of the problem is within the system” through the creation of a family of models that share the generic 2nd order negative feedback loop that generates oscillation. Students can encounter these models in various formats and subject areas. Through repeated exposure to models and materials that incorporate instructional scaffolding principles , students learn to recognize the perceived problematic behavior exhibited is a consequence of the internal system structure. The lessons learned during the pilot project are being used to inform further development of curriculum materials that illustrate Forrester’s characteristics for K-12 students. |
