| Building Slightly More Complex Models: Calculators vs. STELLA |
|
|
Author(s):
Diana M. Fisher |
Subject:
Research |
| |
If students are to develop the potential to effectively manage ubiquitous complex systems, it is becoming increasing important to develop systems thinking concepts and model building skills formally at the pre-college level. This paper describes an experiment conducted in two secondary school classrooms in the Pacific northwestern United States to determine the importance of access to a relatively new modeling tool for students to enable them to successfully create and analyze simple models that are slight extensions of traditional models, as compared with using graphing calculators to build and analyze the same extended model scenarios. |

Cross-Curricular |
| |
Using a STELLA model and then designing an actual bungee jump, students take Barbie bungee jumping.
Complex Systems Connection: Cause within System
This lesson presents a fun way to experiment with an oscillating system. It can be used as a precusor to the Oscillations curriculum designed for the Characteristics of Complex Systems project. |

| Bacteria Sandwich - Mini App |
|
|
Author(s):
Anne LaVigne |
Subject:
Cross-Curricular |
| |
Bacteria Sandwich is a free, engaging, easy-to-use app for students and others to explore how exponential growth can occur when temperatures are optimal for the bacteria. Students can change the initial number of bacteria and temperature to see what happens over 12 hours. How can this bacteria be stopped before it creates a very dangerous lunch? Students can change the elements to determine how to keep those lunches safe!

| Among the Hidden |
|
|
Author(s):
Gail Falewicz |
Subject:
Cross-Curricular |
| |
Gail Falewicz has inherited the Critical Thinking and Reading (CTR) class from Mairead Orpen. (See The Creative Learning Exchange, vol. 22, no. 1, Winter 2013.) http://static.clexchange.org/ftp/newsletter/CLEx22.1.pdf. As the CTR teacher, Gail teaches every 5th grade student at Innovation Academy Charter School (IACS), a public charter school, in Tyngsboro, MA. This is her summary of the class structure and a report of a unit she taught based on the novel "Among the Hidden" by Margaret Peterson Haddix. (1998, Simon and Schuster, Book One in the "Shadow Children" series)

| A System Dynamics Approach to Rabbits (S-shaped growth) (D-4286) |
|
|
Author(s):
Terri Duhon |
Subject:
System Dynamics |
| |
From SDEP. This paper studies S-shaped growth by examining the behavior of a rabbit population. Shows and explains a complete system dynamics model constructed for STELLA.
Complex Systems Connection: Cause within System. This paper can be used in conjunction with the Oscillations curriculum, particularly Lessons 3A, B or C on logistic growth. 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. |
