4/30/2015 NGSS PD Session #6: Models 2

Goals

As a result of this session, participants will be able to:

• Describe the SEP “Developing and Using Models”

• Create a basic lesson or revise a lesson using the aforementioned practice

Modeling can begin in the earliest grades, with students’ models progressing from concrete “pictures” and/or physical scale models (e.g., a toy car) to more abstract representations of relevant relationships in later grades, such as a diagram representing forces on a particular object in a system. (NRC Framework, 2012, p. 58)

• Look at Appendix F-Developing and Using Models • What should students be able to do as part

of this practice? • How can you tell which bullets relate to

science and which relate to engineering?

What is a model?

• Models are external representations of mental (internal) concepts

• A scientific model can be used to see patterns, identify relationships or mechanisms, construct or communicate explanations or make predictions

• All models contain approximations and assumptions

• a scientific model is an abstract, simplified representation of a system that makes its most important features explicit and visible

• include visual representations, 3-D physics structures, schematic or relationship diagrams

• include mathematical representations, analogies, and computer simulations.

• used to represent a system (or parts of a system) under study, to aid in the development of questions and explanations, to generate data that can be used to make predictions, and to communicate ideas to others

• In engineering, models may be used to analyze a system to see where or under what conditions flaws might develop, or to test possible solutions to a problem

Why is modeling important? • Builds scientific understanding • Builds understanding of how science works • Builds practices and skills:

• Systems thinking • Sharing and evaluating • Thinking about evidence
