3D of Science

Proficiency in science?  Proficiency in science; it develops through an understanding that science is both a body of knowledge and an evidence-based, model of building experience that continually extends, refine, and revise that knowledge. Science is identified by four domains/strands: physical science, life science, earth/space science and engineering, technology and application of sciences.

Inquiry vs. Design: Science vs. Engineering?
Scientific Inquiry involves the formulation of a question that can be answered through investigation (science answers the question), while Engineering Design involves the formulation of a problem that can be solved through design (engineering solves the problem); combining both to develop an inquiry design model of instruction.

Three Dimensions of Science: Learning is an algorithm.

Dimension #1- Practices:  The practices describe behaviors that scientists engage in as they investigate and build models and theories about the natural world and the key set of engineering practices that engineers use as they design and build models and systems. What is an appropriate claim for my observation; is it an answer to a question or a solution to a problem?

Dimension #2- Cross-Cutting Concepts: Science and Engineering are not built in isolation. Cross-Cutting concepts bridge the strands of science and engineering through helping students identify patterns, similarity, and diversity; cause and effect; scale, proportion and quantity; systems and system models; energy and matter; structure and function; stability and change. What is the relationship between the evidence collected and the claim?

Dimension #3- Disciplinary Core Ideas (DCI): Student access to core ideas have a broad importance across science or engineering disciplines, provide a key tool for understanding or investigating complex ideas and solving problems, relate to societal or personal concerns, and can be taught over multiple grade levels at progressive levels of depth and complexity. Does the reasoning provide support for the claim and communicate understanding with domain-specific terms?



Student Goals for Science:
Keeping it Real

• develop a deeper understanding of science
beyond memorizing facts.

• experience scientific and engineering practices used by professionals.

Focus of Student Proficiency for Science in Middle School (6-8)

•  physical and chemical interactions that affect our world.

•  factors that affect organism survival and reproduction.

•  factors that influence our planet and all celestial bodies.

• how to optimize design solutions.
