NGSS @ NSTA - View the series

This web seminar took place on March 19, 2013, from 6:30 p.m. to 8:00 p.m. eastern daylight time. The presenters were Amy Taylor and Kelly Riedinger from the University of North Carolina Wilmington. This was the third 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. Taylor began the presentation by discussing the definition of scale. Next, Dr. Riedinger talked about the role of scale, proportion, and quantity in NGSS. Participants shared their own experiences teaching about scale in the classroom before the presenters described additional instructional strategies that can provide students with a real-world understanding of this crosscutting concept. Dr. Taylor and Dr. Riedinger showed examples of activities from elementary, middle, and high school. They shared video clips and other resources that can help educators build their capacity for teaching about scale.


Seminar participants received an NSTA SciGuide. 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:

  • “The presenters provided so many relevant classroom examples. I am really looking forward to checking out the online resources and implementing more specific instruction into scale in my classes.”
  • “The content was excellent and is going to prove useful as we move into using NGSS.”

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