The Surprising World of Complex Systems:

This lesson introduces students to complex systems and to basic concepts from the field of system dynamics that lie at the heart of systems thinking. These concepts include stocks and flows, feedback loops, unintended consequences, and the basic principle that the behavior of complex systems can best be understood by looking at the system as a whole, and specifically by analyzing the system’s underlying structure. The lesson introduces these topics through an immersion in (and a role-play simulation of) the dynamics of urban recycling systems, many of which have been thrown into crisis in the past two years. Through this current-affairs example of complex systems in crisis, we identify some key structural features that help to explain how these systems behave over time. We also discover how well-intentioned action can cause negative unintended consequences when we try to intervene in a complex system without understanding how it operates.

Lesson Study Resource Kit

Clarifying Water Quality: A grade 6-7 Lesson Study MEA Toolkit:

This toolkit supports the development of an instructional unit on water quality that aligns with science, mathematics and English/Language Arts standards for students in grades 6 and 7. The elements of this toolkit were assembled based upon their suitability for constructing a multi-day instructional unit on water quality that corresponds with the 5E Learning Cycle of engage, explore, explain, elaborate, and evaluate. At the heart of this toolkit is a Model Eliciting Activity (MEA) created by the Institute for P-12 Engineering Research and Learning (INSPIRE), housed at Purdue University. The INSPIRE Water Filter MEA is designed to integrate instruction in the subjects of science, math, engineering design, and English Language Arts. Your task as a lesson study team is to analyze the materials that are included in this toolkit and evaluate how they can be incorporated in a 5-E instructional unit plan that complies with the standards for science, English/Language arts and mathematics that are indicated. Ultimately, your team will design a three to five day unit on water quality that incorporates the materials provided in this toolkit. As you study these resources it is important to make note of any deficiencies or gaps that will need to be addressed and make modifications in the lesson resources and activities where needed.
