California recently released the first DRAFT of their Science Curriculum Framework. There is currently a 60 day public review process where stakeholders can give feedback.
I think this document (It’s a large piece of text with multiple sections!) will be helpful to other states, districts, and schools who are continuing to implement the Next Generation Science Standards.
I have only skimmed the document but am finding it to be very helpful especially with designing instructional modules and learning sequences. I know many districts will also be interested in the two different course models for High School science.
You can access the DRAFT CA Science Curriculum Framework HERE.
You can view a November 17th, 2015 webinar on the framework HERE.
