Assessing the Genetics Content in the Next Generation Science Standards

Area of Science:

• Genetics Education
• Science Standards
• STEM Education

Background:

• Science standards are crucial for K-12 STEM education in the U.S.
• Previous research has focused on political impacts, not content coverage.
• Assessing genetics content coverage in standards is vital for genetic literacy.

Purpose of the Study:

• Evaluate genetics content coverage in the Next Generation Science Standards (NGSS).
• Compare NGSS genetics coverage to state science standards.
• Determine NGSS potential to enhance genetic literacy.

Main Methods:

• Used American Society of Human Genetics (ASHG) core concepts as a benchmark.
• Expert reviewers assessed NGSS for concept identification reliability.
• Compared NGSS genetics content against state-level science standards.

Main Results:

• Expert reviewers had low reliability identifying ASHG core concepts in NGSS.
• Gaps were found in essential genetics concepts, particularly inheritance patterns.
• NGSS generally offer better genetics content coverage than state standards.

Conclusions:

• NGSS show potential for genetic literacy but require viewing alongside disciplinary core ideas (DCIs).
• Inconsistent interpretation of NGSS content coverage is a concern.
• Addressing gaps in inheritance concepts is crucial for comprehensive genetics education.
