Technology provides a vehicle for changing some of the experiences pre-college students can have in learning math and science core concepts. It is undeniable that complex problems face the global community in its efforts to control the negative impact humans have had and continue to have on the environment and in interactions with each other, the latter apparent from the ease with which pandemics can occur. Pre-college students can gain an enormous advantage in (potentially) making better-informed decisions when they are voting adults if they are taught to use tools and analytical methodologies that help them study problems that retain a reasonable amount of complexity. Mathematics and science classes are natural environments for students to begin to use the System Dynamics modeling method to enhance their quantitative analysis skills. This workshop is designed to help pre-college (and undergraduate university) instructors learn how they might transition their courses to incorporate the System Dynamics modeling method. The software that will be used will be Stella, but the concepts apply equally well when using the Vensim software. This is a hands-on model-building workshop for teachers of secondary (and undergraduate) mathematics and science classes that will show one path that can be used to take a traditional curriculum and infuse activities that lead to complex systems analysis. The lessons start out with some kinesthetic activities followed by building relatively small simulation models. The lessons provided can be used with their students immediately. Other resources will be described for teachers who are interested in learning more about system dynamics modeling. Participants should bring a laptop to the workshop.
