New MA science standards

Start here

The Massachusetts Board of Elementary and Secondary Education is adopting revised science standards. They are based on the Next Generation Science Standards, which itself is based on A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012), from the National Research Council of the National Academies.

External link: Adoption of 2016 Science and Technology/Engineering Standards

The Board of Early Education and Care (EEC) is scheduled to vote to adopt the Pre-Kindergarten STE standards on February 9, 2016. …Assuming the Board of Elementary and Secondary Education votes to adopt the 2016 STE Standards, the Department will then copyedit the full 2016 Massachusetts Science and Technology/Engineering Curriculum Framework. The Framework includes the standards and a variety of additional guidance and supporting materials….

We expect to publish and post the completed 2016 STE Curriculum Framework in early spring 2016. At that point, the Department will distribute copies … to schools… for their use in improving curriculum, instruction, and assessment in science and technology/engineering starting in the 2016-17 school year….high school STE MCAS assessments will be revised later on a timetable that provides fair notice to students and schools with respect to the science testing component of the state’s Competency Determination (high school graduation) requirement.

Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity’s most pressing current and future challenges. The United States’ position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students’ interest and provide them with the necessary foundational knowledge in the field.

A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators.

The high school Introductory Physics standards build from middle school and allow grade 9 or 10 students to explain additional and more complex phenomena central to the physical world. The standards expect students to apply a variety of science and engineering practices to three core ideas of physics:

Motion and Stability: Forces and Interactions support students’ understanding of ideas related to why some objects move in certain ways, why objects change their motion, and why some materials are attracted to each other while others are not. This core idea helps students answer the question, “How can one explain and predict interactions between objects and within systems of objects?” Students are able to demonstrate their understanding by applying scientific and engineering ideas related to Newton’s Second Law, total momentum, conservation, system analysis, and gravitational and electrostatic forces.

A focus on Energy develops students’ understanding of energy at both the macroscopic and atomic scale that can be accounted for as either motions of particles or energy stored in fields. This core idea helps students answer the question, “How is energy transferred and conserved?” Energy is understood as quantitative property of a system that depends on the motion and interactions of matter and radiation within that system, and the total change of energy in any system is always equal to the total energy transferred into or out of the system. Students apply their understandings to explain situations that involve conservation of energy, energy transfer, and tracing the relationship between energy and forces.

Waves and Their Applications in Technologies for Information Transfer support students’ understanding of the physical principles used in a wide variety of existing and emerging technologies. As such, this core idea helps students answer the question, “How are waves used to transfer energy and send and store information?”

Students are able to apply understanding of how wave properties and the interactions of electromagnetic radiation with matter can transfer information across long distances, store information, and investigate nature on many scales. Models of electromagnetic radiation as either a wave of changing electric and magnetic fields or as particles are developed and used. Students understand that combining waves of different frequencies can make a wide variety of patterns and thereby encode and transmit information. Students can demonstrate their understanding by explaining how the principles of wave behavior and wave interactions with matter are used in technological devices to transmit and capture information and energy.
