Basic principles <strong>of</strong> systems thinking can be<br />

usefully applied to education reform. For this<br />

purpose the authors have adapted here concepts<br />

Donella H. Meadows presents in her 2008 book<br />

Thinking in <strong>System</strong>s: A Primer.<br />

• A system is more than the sum <strong>of</strong> its parts.<br />

Information is one <strong>of</strong> the key factors influencing<br />

the connections and relationships between parts<br />

in the system.<br />

• <strong>The</strong> function, or purpose, <strong>of</strong> the system drives<br />

system behavior. Sometimes the actual function<br />

is not obvious, and may be different from the<br />

stated purpose<br />

PlACES TO INTERVENE<br />

IN A SYSTEM<br />

1. Transcending<br />

paradigms<br />

2. Paradigms<br />

3. Goals<br />

4. Self-organization:<br />

evolution<br />

5. Rules: incentives,<br />

sanctions<br />

6. Information flows<br />

7. Reinforcing feedback<br />

loops<br />

8. Balancing feedback<br />

loops<br />

9. delays: length <strong>of</strong> time<br />

to affect change<br />

• <strong>The</strong> structure <strong>of</strong> the system is a source <strong>of</strong> behavior. 10. Stock and flow<br />

structure<br />

• <strong>The</strong> foundations <strong>of</strong> a system are stocks and flows.<br />

11. Buffers: size <strong>of</strong><br />

Stocks are the parts that you can see, count,<br />

stabilizing stocks<br />

and measure at any given time. Stocks can be 12. Numbers:<br />

parameters, such<br />

physical—like teachers, books, schools, but they<br />

as subsidies, taxes,<br />

can also be intangible factors like information,<br />

standards<br />

beliefs, mental models, self-confidence, goodwill,<br />

or credibility. Flows are the elements that change<br />

stocks over time, which can also be physical (new<br />

schools, graduates <strong>of</strong> teacher colleges) or intangible (new information, new<br />

models, experiences).<br />

• Feedback loops are causal connections between stocks and flows. Feedback<br />

loops can work to balance the system and return it to equilibrium, providing<br />

both a source <strong>of</strong> stability and a source <strong>of</strong> resistance to change. Reinforcing<br />

loops can strengthen existing trends, which can lead to growth or collapse.<br />

—From Thinking in <strong>System</strong>s:<br />

A Primer by Donella H. Meadows<br />

Stocks act as buffers, or shock absorbers, in systems. In education, the concept<br />

<strong>of</strong> stocks also applies to individuals. In an education system, the stock <strong>of</strong> existing<br />

teachers with pre-existing skills, knowledge, and attitudes is an inherent change<br />

buffer when the replacement flow <strong>of</strong> new teachers entering the system may be less<br />

than 2 percent <strong>of</strong> the stock each year. Teachers, principles, ministers, parents all<br />

have skills they are comfortable with, beliefs about the right way <strong>of</strong> doing things,<br />

and attitudes that reflect culture, education, and history. <strong>The</strong>se stocks are not<br />

immutable—but they are resistant to quick change.<br />
