Came across this draft of "A Framework for Science Education" from The National Academies. I'm still skimming through it on my work breaks, but so far - good stuff! I've always thought our K-12 education system needed some revamping, with more focus on critical thinking skills. So far these recomendations are in line with changes I would like to see made. I'll post an update if I come across something I disagree with and any comments I have for their earth science topic recommendations.

They also have a brief survey to take if you are interested in providing feedback.
