The article discussed that there were three major dimensions, which were scientific and engineering practices, crosscutting concepts that unify study of science and engineering through common application, and core ideas in areas of physical sciences, life sciences, earth and space sciences, engineering, technology and application of science.These three together must be incorporated in the classroom for effective science learning. When combined the student acquires basic knowledge of the subjects and how they relate to each other and are given tools to investigate intriguing scientific phenomena in the future.
They define practices as skill + knowledge, crosscutting concepts are define as applications across all domains and disciplinary core ideas as the following: broad importance in sciences, provide tool for understanding idea and solving problems, relate to students, and be teachable and learnable over grades.
Practices for classrooms
- Asking ?s and defining problems 2. Developing and using Models 3. Planning and carrying out investigations 4. Analyzing and interpreting data 5. Using math and computational thinking 6. forming explanations and designing solutions 7. Argument from evidence 8. Obtaining evaluating and communicating information
- Sphere 1- investigation of empirical inquiry
- Sphere 2- explanations or designs using reasoning, creative thinking and modeling
- Sphere 3-ideas are analyzed, debated, and evaluated
