A Framework for K–12 Science Education provides a broad set of learning expectations for students as they study science and engineering throughout the K–12 years. Released by the National Research Council (NRC) in July, the Framework guides the writers of the forthcoming Next Generation Science Standards (NGSS); will influence curriculum, assessment, and teacher professional development decisions for years to come; and ultimately will help inspire new generations of science and engineering professionals and scientifically literate citizens.
