The Four Strands of Scientific Proficiency
Students who understand science: Know, use, and interpret scientific
explanations of the natural world Generate and evaluate scientific evidence
and explanations Understand the nature and development of
scientific knowledge Participate productively in scientific practices
and discourse

The Four Strands of Scientific Proficiency
• The four strands are interwoven in learning. Advances in one strand support advances in the others.
• The strands emphasize the idea of “knowledge in use” – that is students’ knowledge is not static and proficiency involves deploying knowledge and skills across all four strands.
• Students are more likely to advance in their understanding of science when classrooms provide learning opportunities that attend to all four strands.

The Framework has identified seven key Crosscutting Concepts that serve a variety of purposes in science. This is one way to organize them for instruction.

• Science is fundamentally about explaining phenomena by determining how or why they occur and the conditions and consequences of the observed phenomena. – McNeill and Krajcik, 2008
