Study Notes

North Carolina K-12 Science Support Documents - Biology 2023

The 2023 North Carolina K-12 Science Standards were approved on July 6, 2023.
The standards are designed to help students continually improve their science knowledge and abilities.
The standards aim to foster conceptual understanding, develop scientifically literate students, and provide opportunities to build knowledge and practices within each grade band or course.
Science Support Documents are resources for teachers, educators, administrators, and parents to support understanding and planning.
They don't replace curriculum but guide teachers in discerning and describing student strengths in meeting grade-level science proficiency.
Effective science teaching emphasizes consistent, coherent practices across K-12 to align with Framework for K-12 Science Education.
Active engagement in science & engineering practices and application of crosscutting concepts are essential for deeper understanding of disciplinary core ideas at all grade levels.
Schools are responsible for establishing safe science laboratory practices and adhering to legal standards of care.
Many individuals, including educators, were involved in creating the NC K-12 Science Support Documents.

Resources for K-12 Science Support Documents

Benchmarks for Science Literacy
Earth Science Literacy Principles
NAEP Science Assessment Framework (2019 & 2028)
National Research Council: A K-12 Framework for Science Education
National Science Teaching Association
Ocean Literacy Principles
STEM Teaching Tool #41
Trends in International Mathematics and Science Study (TIMSS) 2023 Assessment Framework

Strand Organization

Standards are organized in K-12 vertical progressions (11 strands), increasing in sophistication through the grade bands.
Standards are grouped into three domains: Physical Science, Life Science, and Earth & Space Science.

Standards and Objectives

North Carolina's Standard Course of Study sets expectations for student learning.
Standards & objectives describe what students need to know to master the given content.
Standards provide broader content, while objectives give specific examples of content that must support a standard.
Each objective includes a science & engineering practice, a verb from Revised Bloom's Taxonomy, and a disciplinary core idea.
Objectives in the 2023 standards define the standard level of knowledge, understanding, and skill.
Honors level course clarifications and evaluative tools will be provided separately.

Science and Engineering Practices (SEP)

Student engagement in their learning.
Describing the scientific process and procedures.
Providing insight into the nature of science and engineering practices for all students.

Crosscutting Concepts (CCC)

Using this framework will strengthen connections between disciplines.
Helps students develop a coherent and scientifically based view of the world.
Helps students in making sense of phenomena.
Essential conceptual tools along with SEPs to help students explain and predict.

Disciplinary Core Ideas (DCI)

Provides conceptual ideas for students' knowledge in specific grade bands.
Supports the explanation of science phenomena.
