Next Generation Science Standards
NGSS Crosscutting Concepts: Systems and System Models
NGSS @ NSTA - View the series

This web seminar took place on June 11, 2013, from 6:30 p.m. to 8:00 p.m. eastern daylight time. The presenter was Ramon Lopez from the University of Texas at Arlington. This was the seventh web seminar in a series of seven focused on the crosscutting concepts that are part of the Next Generation Science Standards (NGSS).

The PowerPoint, related resources from the NSTA Learning Center, and web links from the presentation are now contained in the above resource collection. Clicking on the collection link will place it in your Learning Center, My Library, neatly organized under the My Resource Collections tab.


Dr. Lopez began the presentation by discussing the importance of systems and system models as a crosscutting concept. He talked about the key features of a system: boundaries, components, and flows and interactions. Dr. Lopez also described different types of system models, including conceptual, mathematical, physical, and computational models. Participants discussed their current classroom applications of systems and system models and brainstormed ways to address challenges associated with teaching this crosscutting concept.


A certificate of attendance was deposited into participants' My PD Record and Certificates area in the NSTA Learning Center for completing the evaluation form at the end of the program.


Here are some comments provided by the participants at the end of the Web Seminar:

  • “Provided a lot more conceptual structure to my understanding of systems and system models and how these ideas can be operationalized in the classroom at various grade levels.”
  • “It got me thinking about supporting students to create their own systems models and test them against reality.”

Thanks to the participants and the presenter for the learning opportunity, the interactions, and a job well done!
