Others have identified connections between children’s culturally based storytelling and their engagement in argumentation and science inquiry, and some of these researchers have also documented pedagogical means of using such connections to support students’ science learning and promote educational equity . The research demonstrates the importance of embracing diversity as a means of enhancing learning about science and the world, especially as society in the United States becomes progressively more diverse with respect to language, ethnicity, and race.
The goal of educational equity is one of the reasons to have rigorous standards that apply to all students. Not only should all students be expected to attain these standards, but also work is needed to ensure that all are provided with high-quality opportunities to engage in significant science and engineering learning.
STRUCTURE OF THE FRAMEWORK
Based on the guiding principles outlined above, we have created a framework—comprised of three dimensions—that broadly outlines the knowledge and practices of the sciences and engineering that all students should learn by the end of high school:
• Dimension 1 describes scientific and engineering practices.
• Dimension 2 describes crosscutting concepts—that is, those having applicability across science disciplines.
• Dimension 3 describes core ideas in the science disciplines and of the relationships among science, engineering, and technology.
The three dimensions of the framework, which constitute the major conclusions of this report, are presented in separate chapters. However, in order to facilitate students’ learning, the dimensions must be woven together in standards,
