USA Next Generation Science (& Engineering) Standards (NGSS)

In the United States of America a grassroots effort was started to create the Next Generation Science Standards. We add the Engineering explicitly as that is a more accurate description. Read more about the whole NGSS on the NGSS Website.

There are three dimensions in the NGSS, Cross Cutting Concepts, Science and Engineering Practices and Disciplinary Core Ideas.  This Systems Literacy initiative is interested in the Cross Cutting Concepts.

They have associated matrix of performance standards.

Number 4 in the list is Systems and system models. Here is the list of the seven cross cutting concepts:

1. Patterns. Observed patterns of forms and events guide organization and classification, and they prompt questions about relationships and the factors that influence them.

2. Cause and effect: Mechanism and explanation. Events have causes, sometimes simple, sometimes multifaceted. A major activity of science is investigating and explaining causal relationships and the mechanisms by which they are mediated. Such mechanisms can then be tested across given contexts and used to predict and explain events in new contexts.

3. Scale, proportion, and quantity. In considering phenomena, it is critical to recognize what is relevant at different measures of size, time, and energy and to recognize how changes in scale, proportion, or quantity affect a system’s structure or performance.

4. Systems and system models. Defining the system under study—specifying its boundaries and making explicit a model of that system—provides tools for understanding and testing ideas that are applicable throughout science and engineering.

5. Energy and matter: Flows, cycles, and conservation. Tracking fluxes of energy and matter into, out of, and within systems helps one understand the systems’ possibilities and limitations.

6. Structure and function. The way in which an object or living thing is shaped and its substructure determine many of its properties and functions.

7. Stability and change. For natural and built systems alike, conditions of stability and determinants of rates of change or evolution of a system are critical elements of study.
