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 />
