NSTA has released a resource for helping parents and the rest of the school community to understand the Next Generation Science Standards.

Curating Transformative Science Education Resources
Science for All 
Thanks, Kirk, for this valuable resource! I appreciate that it provides a ready-made “initial communication tool” for parents to start understanding NGSS, and it also addresses typical questions that parents have, for example:
– How will NGSS change my child’s science classroom?
– Are the NGSS different from the Common Core State Standards?
– What can I do to prepare my child for a STEM-filled world?
I will be sharing this with teacher leaders to get them thinking about ways to initiate “NGSS-dialogue” with families.
