Aligning the Next Generation Science Standards (NGSS) with the Common Core State Standards for Mathematics (CCSSM) in states that have implemented the Common Core requires intentional modifications to ensure seamless integration and coherence across STEM subjects. Below are specific modifications and their potential impacts on assessment and evaluation:

Specific Modifications to NGSS

  1. Explicit Cross-References to CCSSM

    • Modification: Integrate explicit cross-references within NGSS performance expectations to highlight the specific CCSSM standards that align with the science content. For example, when addressing data analysis in science, directly reference the corresponding CCSSM standards for statistics and probability.
    • Impact: This ensures teachers and curriculum developers can identify natural points of integration, fostering a more cohesive STEM education.

  2. Mathematics-Embedded Performance Expectations

    • Modification: Revise NGSS performance expectations to include mathematically rigorous components. For instance, specify that students must use algebraic thinking or geometric reasoning to solve scientific problems.
    • Impact: This promotes deeper mathematical understanding within scientific contexts, preparing students for integrated STEM assessments.

  3. Clarify Mathematical Practices in Science

    • Modification: Align NGSS science and engineering practices (e.g., "Using Mathematics and Computational Thinking") with CCSSM mathematical practices (e.g., "Modeling" or "Reasoning Abstractly").
    • Impact: This ensures students apply consistent reasoning and problem-solving skills across STEM disciplines, making assessments more reflective of integrated learning.

  4. Domain-Specific Integration

    • Modification: Develop NGSS supplements that map specific science topics (e.g., physics, biology) to corresponding CCSSM domains (e.g., algebra, geometry). For example, link motion and forces in physics to linear equations and graphs in algebra.
    • Impact: This facilitates targeted instruction and assessment, ensuring students apply math skills appropriately in scientific contexts.

  5. Incorporate Mathematical Literacy in Science

    • Modification: Modify NGSS to include expectations for interpreting and communicating scientific results using mathematical representations (e.g., graphs, tables, equations).
    • Impact: This enhances students' ability to connect math and science, improving their performance on integrated STEM assessments.

  6. Professional Development for Teachers

    • Modification: Provide professional development resources for teachers to understand how NGSS and CCSSM intersect, including co-planning and co-teaching strategies.
    • Impact: This ensures educators are equipped to design and implement integrated STEM lessons and assessments effectively.

Impact on Assessment and Evaluation

  1. Integrated STEM Assessments

    • Impact: Modifications to NGSS would necessitate the development of assessments that evaluate both scientific understanding and mathematical proficiency. For example, performance tasks could require students to model a scientific phenomenon using mathematical equations.
    • Outcome: Assessments would better reflect real-world STEM applications, where math and science are inherently interconnected.

  2. Cross-Disciplinary Performance Tasks

    • Impact: Assessments would need to include tasks that integrate math and science, such as solving engineering design challenges or analyzing environmental data using statistical methods.
    • Outcome: Students would demonstrate their ability to apply math and science together, preparing them for STEM careers.

  3. Formative Assessments for Math-Science Integration

    • Impact: Teachers would need to use formative assessments to monitor students' ability to apply math skills in scientific contexts. For example, exit tickets or quizzes could focus on mathematical reasoning within a science topic.
    • Outcome: This would help identify gaps in understanding and inform targeted instruction.

  4. Changes in Scoring Rubrics

    • Impact: Scoring rubrics for assessments would need to include criteria for both scientific accuracy and mathematical rigor. For example, a science project rubric might evaluate the correctness of a mathematical model used to explain a phenomenon.
    • Outcome: This ensures that assessments measure the full range of STEM skills, not just scientific knowledge.

  5. Technology-Enhanced Assessments

    • Impact: Assessments could leverage technology to simulate real-world STEM problems, requiring students to apply math and science together. For example, simulations of climate modeling or population dynamics.
    • Outcome: This prepares students for the digital tools used in STEM professions and enhances the validity of assessments.

  6. Teacher Collaboration in Grading

    • Impact: Mathematics and science teachers would need to collaborate on grading integrated assessments, ensuring consistency and understanding of cross-disciplinary expectations.
    • Outcome: This fosters a more holistic view of student learning and strengthens teacher teams.

Conclusion

Modifying NGSS to align with CCSSM requires intentional integration of mathematical practices, cross-references, and performance expectations. These changes would lead to more cohesive STEM instruction and assessment, ensuring students develop the skills to apply math and science together effectively. Assessments would become more comprehensive, evaluating not only scientific knowledge but also the mathematical reasoning and problem-solving skills essential for success in STEM fields.
