The Three Dimensions
The three dimensions from A Framework for K-12 Science Education (NRC, 2012) provide clarity for the how and what of science teaching using these new standards. The integration of Science and Engineering Practices (SEPs), Disciplinary Core Ideas (DCIs) and Crosscutting Concepts (CCCs) work together to help students engage in sense-making and develop understanding. These three dimensions, supported by Nature of Science (NOS) principles provide the groundwork for the NGSS.
3d Models
Houseal Model wSS citation FINAL.pdfExplanatory Model
Use this "explanatory" version of our 3D model to identify the specific components of each dimension and what they might look like alone, in pairs, and all together.
Houseal Model Blank with SS citation FINALpdf (1).pdfBlank Model
This "blank" version of our 3D model can be used for planning and evaluative purposes. It allows you to identify (map) how components of your lesson/unit correspond with the three dimensions and identify convergences and gaps.
3D model no explanations 9-21-17.pdfComponent Model
This "poster" model provides a quick explanation of dimensions and what 3D teaching looks like. It can be printed for classroom use.
3D Teaching
Use the models to explore what teaching might look like within each dimension, within two-dimensions, and three-dimensional (3D) instruction. 3D instruction, the goal of the NGSS, creates a learning environment where students are not just 'consumers' of science, but also 'producers' of scientific knowledge.
