Building on the strong foundation of previous studies seeking to identify and describe major ideas for K-12 science education in the US, this report offers a framework to address current weaknesses such as a lack of systematic organization of science education across multiple years of school, emphasis on discrete facts and focus on breadth over depth, and lack of opportunities for students to experience how science is actually done. The report recommends that K-12 science education be built around three dimensions--science and engineering practices, crosscutting concepts unifying the study of science and engineering through their common application across fields, and core ideas in four disciplinary areas, including the physical sciences; life sciences; earth and space sciences; and engineering, technology, and applications of science. The report outlines the new vision, describes the three dimensions in detail, and suggests next steps for realizing the vision. Annotation ©2012 Book News, Inc., Portland, OR (booknews.com)
