KnowAtom Brings the Three Dimensions of NGSS to Life

Professional development that explores the relationship between STEM practices, crosscutting concepts, and disciplinary core ideas.

Dimension 1: STEM Practices

Explore how to teach the eight science and engineering knowledge skills with a focus on higher-order thinking and real-world application. We link achievement of Common Core ELA and Common Core Math goals to STEM practices. The eight practices are:

1

Asking questions (science) and defining problems (engineering)

2

Developing and using models

3

Planning and carrying out investigations

4

Analyzing and interpreting data

5

Using mathematics and computational thinking

6

Constructing explanations (science) and   designing  solutions (engineering)

7

Engaging in argument from evidence

8

Obtaining, evaluating, and communicating information

Dimension 2: Crosscutting Concepts

Leverage the links between all of the different domains of science. These concepts highlight relationships in the way elements of a system behave, giving students a structure by which to make sense of content and understand each system’s behavior. The systems are divided into the following seven categories:

1Patterns

2Cause & effect

3Scale, proportion & quantity

4Systems & system models

5Energy & matter

6Structure & function

7Stability & change

Dimension 3: Disciplinary Core Ideas

Focus on the four disciplinary core ideas of the Next Generation Science Standards as context for learning:

Engineering, Technology, & Applications of Science

Physical Sciences
