Abstract
Over the 1999-2000 academic year, an introductory evening
and weekend course in system dynamics was held at the high school in Sturgeon
Bay, Wisconsin, USA.The students consisted of high school students, high school
teachers, and community members.In the hope that our story may benefit others
interested in attempting something similar, this paper discusses three aspects
of our experience, including:
-
How the course got started
-
Curriculum materials
-
Some initiatives undertaken by the students on their own
volition
1.0
How the course got started… illustrating how community
sustainability can be a mechanism for introducing system dynamics in a community
The course came about primarily because of the
accidental coming-together of two independent multi-faceted initiatives. In one
initiative, Larry Smith, Susan Gullion, and Roy Aiken had been taking several
paths toward developing public and government awareness of, and action on,
sustainability/stewardship in Door County and its communities, and the larger
region of Northeastern Wisconsin. The other initiative had been Paul Newton's
efforts at promoting system dynamics in K-12 education in nearby Green Bay, WI.
Larry, Susan, and Roy had, independently of Paul, decided that the tools that
they would promote toward their community sustainability agenda were 1)
sustainability principles, 2) system dynamics, and 3) dialogue. Simultaneously,
one of Paul's initiatives had been the formation of a system dynamics study
group for educators, which, somehow, Susan became aware of and joined. Learning
of one another's initiatives through Susan, Larry, Susan, and Roy saw Paul as a
system dynamics knowledge resource, and Paul saw community sustainability as a
mechanism for introducing system dynamics in K-12 education. Thus, the two
initiatives were joined…
Some months later, while Paul was home in
Wisconsin for the Christmas holidays from his system dynamics studies at
Norway, he and Roy met with the Sturgeon Bay Superintendent, High School
Principal, and District Curriculum Director, and proposed a high
school/community system dynamics course. The idea was to find a high school
teacher who would be interested in learning and teaching system dynamics. The
teacher would get started learning system dynamics at Trinity College during
the summer, and Paul and the teacher would then teach the first course together
in the fall. The course would be funded by local business, government, and
charitable organizations, which, in return for their funding, would also be
offered seats in the course along with the high school students. Further, the
course would be advertised to other K-12 teachers who might be interested and
would be held either the first or last period of the day to facilitate
participation by the adult students.
Despite some communication snafus it all came
together. After playing a bit with Stella® on the computer in his basement, Don
Ziegelbauer, a high school social studies teacher, became very interested in
co-teaching the class with Paul. In July, he and Paul attended Course 1 of the
Waters' Center's 5 course sequence for teachers at Trinity College in
Burlington, Vermont.Don recruited three other teachers (1 biology, 1 economics,
and 1 social studies) to take the course, as well as five high school
sophomores. Four adults enrolled in the course, including Roy Aiken (director
of the Door Property Owners Association, Larry Smith (a social sciences
professor at the University of Wisconsin - Green Bay), Pat Miller (a retiree
who is very active in Door County community issues), and John Jessup (a
business process modeling consultant). The high school students would receive
normal elective credit for the course, with Don being responsible for grading
their work. The class decided to meet each week for two hours on Monday
evenings and three hours on Saturday mornings, for a total of five hours per
week.

Initiatives undertaken by the students on their own volition
3.1 Teaching
a system dynamics course next school year
Don Ziegelbauer was so enthralled by his
introduction to systems that he not only wanted to use it as a tool in his
social studies classes, but he also wanted to teach a course in system dynamics
as a high school elective. In early December he and several of the high school
students taking the first semester's course presented system dynamics to the
Sturgeon Bay School Board, and requested and received approval for Don to teach
a 9 week course beginning in the 2000-2001 school year. Don anticipates that
one or more of the sophomores (or perhaps even the adult) students in our class
this year will be interested in assisting him in teaching the new system
dynamics course.
3.2 Using
systems thinking in their teaching
3.2.1 Steve
Schmelzer
Steve Schmelzer, a high school economics
teacher in the class, has used systems tools in several contexts in his class,
including:
- Demand-side
fiscal policy: Steve used causal loop and stock-flow diagrams as communication
tools. As an aside, he indicates that his students more readily understood
stock-flow than causal loop diagrams.
- Financial
planning: Steve showed his students how to build a simple, first order
financial planning model where inflow was income, outflow was spending, with
budget items feeding expenditures. The students built the model in a lab and
used it to test budgets they had developed prior to the lab.
- Understanding
savings and credit: On the board, Steve showed his students a savings account
stock-flow diagram, then modified the variable names on the diagram to create a
credit stock-flow diagram, illustrating transferability of structure. He then
had the students run experiments in the lab using the
retirement/credit/inflation model from Waters Center's Demo Dozen.
- Steve
had the students study exponential growth in the lab using the Lily Pad model
from Waters Center's Demo Dozen.
- Steve
is planning on attending the Systems Thinking and Modeling in K12 Education
this summer in Oregon.
3.2.2 Don
Ziegelbauer
Don Ziegelbauer has used systems tools in
several contexts, both in and out of the classroom, including:
- Population
studies: Don developed a Mexico to U.S. immigration model that he used both in
class and with the School Board to sell the idea of teaching a systems class.
Both with his classes, and with the School Board, he posited some system
assumptions, and then asked the students/School Board to predict population
behaviors, followed by testing the behavior-over-time resulting from those assumptions.
- Population
studies curriculum development: Don
has developed a population model for local fish populations. He is improving
his model in collaboration with local state DNR (Department of Natural
Resources) personnel, and hopes to use the model as a discussion mechanism
between DNR personnel and his students.
- Prison
overcrowding: One
of Don's students, with Steve Schmelzer's help, developed systems diagrams to
illustrate her prison-crowding project for Don's class.
- Biology
presentation: Don
is working with three of the four sophomores who took our first semester course
to help them develop a simple biology model to present to a biology class.
- Curriculum
for his systems course: Don is
choosing/developing a curriculum for his 9 week systems elective that he will
be teaching this next academic year.
- Don
is continually introducing other teachers and students to system dynamics
applications in education. He is recruiting teachers throughout Door County to
take Waters Center's Course 1 this summer, and he is also recruiting students
for his upcoming system dynamics class.
3.2.3 Jim
Adams
Jim Adams, a history and social studies teacher
at Sevastopol High School (another Door County town, near Sturgeon Bay),
responded to my request for initiatives he had undertaken with the following
(taken from his email to me):
"Most of what I am doing is subtle rather
than full-blown S/D [system dynamics] instruction. I have found myself
introducing BOTGs [Behavior-over-time graphs] and some stock-flow diagrams in
my instruction as we go through various units.
"Last week one of my freshmen students did
a report on Easter Island in our anthropology unit. After her report I began
asking the students questions to get their responses re: what happened. After a
brief discussion we went to the computer lab and I took them through the Easter
Island model. Unfortunately, we didn't get very far with time constraints but I
will be taking them back to the lab on Monday to continue our discussion.
"In the American History class (juniors) I
have used BOTGs for civil rights and immigration. I had the students draw BOTGs
expressing what they thought has happened re: civil rights. They came up with
BOTGs showing: an increase in black voting, changing levels of KKK activity,
more black participation in athletics, etc. I was pleasantly surprised to see
their reaction to using BOTGs. They took to it right away & it stimulated a
lot of good discussion. They would ask why things happened and some of the
students that participate the least in class came up with some rather
perceptive explanations of behaviors.
"I used BOTGs similarly in my unit on
immigration.
"I am not as comfortable with the use of
CLDs yet. I have used some of the ones that we have used in class but I am not
ready to create one 'on the fly' in the class.
"I also have used the population model
from the Demo Dozen in class.
"Outside of the classroom I have been
trying to 'infect' other teachers & my principal. I gave the 'Flying a
Cell' CD [a learning environment demonstration from High Performance Systems,
Inc.] to the science teacher & have tried recruiting him for the summer
class. Dale Carlson(Ag teacher: animal science, forestry, etc.) plans on taking
it, Ade Webber (Econ, World Hist, Geography) is a possible as is Roy Raynier
(Earth Science). Mike Zittlow (Math) has not committed & I plan on sharing
some math models from the CLE with him. Hopefully he will get infected.
"We are just starting the Wars Unit that I
submitted for Course 1 that you, Jeff, & John reviewed. I shared that with
my principal, Randy Watermolen in my professional growth plan review. All
teachers are required to prepare a PGP at the beginning of the year and I chose
to incorporate my S/D class work in my wars unit. The teachers are also
required to have a unit constructed by the end of the year that ties in their
standards & benchmarks. So I killed several birds with one model!
"Next year I have a new assignment
(Current Issues) so I plan on incorporating much of what I have learned in
these courses. This will let me 'test drive' a possible course for the
following school year. After using S/D in Current Issues first semester I plan
on proposing a S/D course for the following school year (2001-2002). Hopefully
Don Ziegelbauer and I can get together this summer to work on it. He is getting
paid to do curriculum work and Randy wants me to put in time this summer for
the Current Issues course so we should be able to dovetail our work."
3.2.4
Larry Smith
Larry Smith (co-author of this paper) is also
selecting system dynamics curriculum to use in his undergraduate economics, global studies, and sustainability
courses at the University of Wisconsin - Green Bay. He is currently looking at
some sustainability curriculum produced by John Heinbokel and Jeff Potash at
The Waters' Center. He will also look at Professor Khalid Saeed's
sustainability and development economics work and software, as well as Decision
Dynamics' "Rural Community Modeler" software
(http://www.decisiondynamics.com) as potential resources. While choices about
materials to use in these courses are not yet firm, available resources like
those mentioned above could clearly enhance several of Larry’s courses in both
the lower-level general education program and at the upper-level in both
economics and in the interdisciplinary undergraduate degree program in social
change which he chairs.
3.3
Introducing system dynamics at a seminar for other teachers
Every spring the teachers in all of the school
districts in Door County gather for a day they call T3 ("Teach the
Teachers").Don Ziegelbauer and Jim Adams, with Steve Schmelzer's support,
took it on themselves to offer a 1-hour introduction to system dynamics in
education as part of this day. Fifteen teachers attended their session, and, as
a result, several teachers have expressed interest in learning more about
system dynamics.
3.4
Recruiting other teachers to take Waters' Center's Course 1 this summer
Don and several of the other students are
promoting the idea of inviting The Waters' Center teach their Course 1 this
summer (2000) in Door County. Don believes that he can recruit 15 teachers
(probably half of whom heard about system dynamics at the T3 discussed above)
who would be very interested in taking this weeklong full-time course. This is
seen as critical to continuing Door County's momentum into next year, because,
the teachers who complete Course 1 in the summer will be able to take Course 2
over the internet in the fall, enabling Door County to have a group of ten to
twenty teachers who are simultaneously learning to use system dynamics for
learning.
3.5
Beginning to use systems thinking on community initiatives
Larry Smith (co-author of this paper) lives in
the township of Nasewaupee which is adjacent to Sturgeon Bay in the heavily
recreational and problematically attractive Door County, Wisconsin on the
western shore of Lake Michigan. The Nasewaupee Land-Use Planning Committee,
which Larry chairs, now works with a consulting firm to find creative
approaches to land-use planning and management for the town. But the town can’t
manage its fate alone, and Larry hopes that tools like systems dynamics will
help the committee and town develop meaningful partnerships with other entities
in Door County and, perhaps the larger region, to find or create useful
approaches to evolving problems of sprawl. Larry hopes to use system dynamics
alongside the consulting teams' efforts for the purpose of better understanding
and evaluating their policy recommendations and to provide visual models of
likely outcomes of implementation of land use tools in the Town. He also hopes
that use of system dynamics in conjunction with land use visualization tools as
in the package offered by the Prescott College/NASA (Arizona) program described
at http://www.prescott.edu/nasa/pnf_contents.htm
will help further this effort.
3.6
Doing sessions on system dynamics at an annual Wisconsin-wide education
conference
The GWETC (Governor's Wisconsin Educational
Technology Conference) is held every year in a different location in Wisconsin.
It will be held in October 2000 in Madison. Members of the class have proposed
to do three different presentations at this conference; we hope their
applications will be approved. The titles of their presentations are:
- "System
Thinking and Computer Modeling as tools in Grades 7-12 Classrooms"
- "Computer
Simulations: From Student Education to Learning Communities"
- "Sustainable
Development and Global Studies Utilizing System Dynamics"
4.0 Summary and Further
Information
We have
briefly described three aspects of a continuing community system dynamics
course: how the course got
started, curriculum materials used, and some initiatives undertaken by the
students on their own volition. A more comprehensive paper is available at http://www.arme.cornell.edu/paulnewton/home.htm, including
more on the curriculum, educational process, use of distance education tools,
and some reflections on our experience. Our reflections address three
questions: the viability of community sustainability as a mechanism for
introducing system dynamics in a community; the roles and value to the effort
of a 'citizen-advocate' and a 'teacher-advocate'; and the degree to which our
curriculum meets its objectives.
