Understanding Three-Dimensional Instruction—The Foundation of NGSS. This introduction proves a simple context for understanding three-dimensional instruction. Using a Venn Diagram, something we might use with our students, we get a flavor for how the science and engineering practices (SEP’s), crosscutting practices (CCC’s) and disciplinary core ideas (DCI’s) work together to provide holistic science teaching and learning.
Flinn’s own Dr. Mike Marvel discusses how NGSS is all about forefronting the practice of science by getting into the lab and doing science.
