With the generous financial and professional support
of the Waters Foundation, we have developed a year-long Systems Thinking Unit
called "Choices" for Amy's 10th Grade Literature classes. In this unit,
students use "Behavior Over Time" graphs, simple "Causal Loops," and STELLA
models to help them examine reasons for and outcomes of choices made by
characters in works such as Sophocles' Antigone, Shakespeare's Julius
Caesar and Golding's Lord of the Flies, as well as several
others. We have found that it is less threatening for students to systemically
examine the behavior of characters in stories before they do the more difficult
work of examining their own choices!
One of the most engaging lessons in this series is when students participate in
a STELLA-guided group conversation about the dynamics of mob anger in Julius
Caesar
, Act III, scene ii, in which Brutus calms the crowd down when they are upset
over Caesar's death, after which Brutus departs and the crafty Marc Antony
slowly whips them back up, culminating in a murderous mob frenzy. Students are
captivated by watching their qualitative understanding about crowd mentality be
transformed into stocks and flows, and then simulated. The STELLA exercise also
unearths previously hidden concepts such as loop dominance; the reinforcing
loop between the stock "Mob Anger" and "Angry Talking Among Themselves;" the
difference between "Calming Leaders" and "Angering Leaders;" and the powerful
effect of adjusting the "Crowd Volatility" converter. And there's just
something really intriguing about watching those computer-generated graphs
sketch out over the course of each run. It is a great visual experience of the
concept of change over time. Throughout the lesson, we reference students' own
experience with the behavior of crowds and ask questions about the choices and
responsibilities of leaders and members within a group of people.
As much as we enjoy teaching the "Choices" series, some of the best evidence of
the power of Systems Thinking lies in the reactions of the students. Here are a
few sample student quotes about the unit:
"Man, I was a bad kid! I had never thought about how I acted when I was little
until we had to graph our behavior. I need to apologize to my Mom!"
"That loop about death and revenge from Antigone
is true. That's the way it still is on the streets."
"Really these guys (writers) didn't make up anything new. They just watched the
cycles in everyday life and wrote about them."
"Systems Thinking helps us recognize patterns in behavior, society, and
emotions. We can then study that information to help us cope with the same
problems in the future."
This was the dream of Barry Richmond, inventor of STELLA, founder of High
Performance Systems, and inspiration to a generation of Systems Thinkers. And
in the end, Systems Thinking is what matters most. It gives students conceptual
and visual tools to "recognize patterns in behavior," to "understand the cycles
of everyday life" and to "cope with the same problems in the future." Perhaps
they will even learn to do a better job than previous generations and to cope
more successfully with the old problems, and with the new problems they will
face going forward.
