How Well Do You Understand the NGSS?How Well Do You Understand the NGSS?
1. I don’t. Should I?
2. I’ve heard of the NGSS, but don’t really know how it impacts students.
3. I’m familiar with the NGSS, but I have questions and would like more specifics
4. I’m very familiar with the NGSS. I may be able to help others understand what it is and its impact.
From Peter McLaren
NGSS Trivia • Was NGSS a Federal initiative?
• The federal government was not involved in this effort and did not fund it. • Who funded NGSS?
• The work undertaken by the NRC and Achieve was being supported by the Carnegie Corporation of New York.
• Who Developed NGSS? • It was state-led, and states will decide whether or not to adopt the standards.• Achieve oversaw the process.• Professional organizations (like ASSS, NSTA), teachers, scientists, engineers, etc. were
heavily involved in development.
• Was the public (teachers or stake holders) involved in the process of creating NGSS?
• The first two drafts were released to the public. The final draft responded to public feedback.
• Lead States provided invaluable feedback throughout the process.

Disciplinary Core Ideas
With a partner, discuss for 1 minute
•What is a disciplinary core idea?
•How is a disciplinary core idea different from traditional science content?
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
NGSS Organized around Disciplinary Core Ideas
• Fewer, clearer, higher• “Many existing national, state, and local standards and
assessments, as well as the typical curricula in use in the US, contain too many disconnected topics given equal priority.” (NRC, 2009)
• Standards and curriculum materials should be focused on a limited number of core ideas.
• Provide a framework to solve problems, explain phenomena, and engage in future learning
• Develop over time
A core idea in K-12 science…• Disciplinary significance
– Has broad importance across multiple science or engineering disciplines, a key organizing concept of a single discipline
• Explanatory Power– Can be used to explain a host of phenomena
• Generative– Provides a key tool for understanding or investigating more complex ideas
and solving problems
• Relevant to peoples’ lives:– Relates to the interests and life experiences of students, connected to
societal or personal concerns • Usable from K to 12
– Is teachable and learnable over multiple grades at increasing levels of depth and sophistication

How are DCIs Different than Science Concepts1. The Framework and NGSS move
teaching away from a focus on presenting numerous disconnected facts to a focus on a smaller number of disciplinary core ideas which learners can use to explain phenomena and solve problems.
2. The ideas in Framework and NGSS describe what students should be able to explain and be able to solve, rather than providing disconnected facts and definitions.

Crosscutting Concepts
For 1 minute, discuss with your partner
•What are crosscutting concepts?
•How are they different from what we had before?
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Crosscutting ConceptsIdeas that cut across and are important to all the science disciplines
1.Patterns
2.Cause and effect
3.Scale, proportion and quantity
4.Systems and system models
5.Energy and matter
6.Structure and function
7.Stability and change
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Science and Engineering Practices
For 1 minute, discuss with your partner
•What are science and engineering practices?
•How are science and engineering practices different from inquiry?
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Scientific and Engineering Practices
1. Asking questions and defining problems
2. Developing and using models
3. Planning and carrying out investigations
4. Analyzing and interpreting data
5. Using mathematics and computational thinking
6. Developing explanations and designing solutions
7. Engaging in argument from evidence
8. Obtaining, evaluating, and communicating information
The practices work together – they are not separated!
The multiple ways of knowing and doing that scientists and engineers use to study the natural world and design world.
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
How practices differ from Inquiry• Practices build on and extend earlier efforts of students
engaging in inquiry to a focus on students investigating, developing, evaluating, and refining ideas to explain phenomena and solve problem.
• Practices shift the focus from science classrooms as an environment where students learn about science ideas to places where students explore, examine and use science ideas to explain how and why phenomena occur.

Practices Change Science Education
Practices shift the focus from the science classroom as environments where students learn about science ideas to places where students explore, examine, and use science ideas to explain how and why phenomena occur.

Performance Expectations
For 1 minute, discuss with your partner
•What are performance expectations?
•How are performance expectations different from traditional standards?
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Content (scientific ideas) is not enough!
• Understanding content is inextricably linked to engaging in practices. Simply “consuming” information leads to declarative, isolated pieces of information.
• Research on how students learn shows that students can’t learn disciplinary content without engaging in disciplinary practices, and they can’t learn these practices without learning the content
• To form useable understanding, knowing and doing cannot be separated, but rather must be learned together
• Allows for problem-solving, decision making, explaining real-world phenomena, and integrating new ideas.
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Content and Practice Work together to Build Understanding
• Scientific ideas are best learned when students engage in practices
• To form useable understanding, knowing and doing cannot be separated, but rather must be learned together
• Allows for problem-solving, decisions making, explaining real-world phenomena, and integrating new ideas
Core Ideas
Practices
Crosscutting Concepts
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Standards integrate core ideas, crosscutting ideas & practices
• “Standards should emphasize all three dimensions articulated in the framework—not only crosscutting concepts and disciplinary core ideas but also scientific and engineering practices.” (NRC 2011, Rec 4)
• “Standards should include performance expectations that integrate the scientific and engineering practices with the crosscutting concepts and disciplinary core ideas. These expectations should require that students demonstrate knowledge-in-use and include criteria for identifying successful performance.” (NRC 2011, Rec 5).
Core idea: PS1.B: Chemical Reactions Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. (MS-PS1-2), (MS-PS1-5)The total number of each type of atom is conserved, and thus the mass does not change. (MS-PS1-5)
Creating performance expectations from core idea + practice
Performance expectation: MS-PS-5 Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
Practice: Developing and using models
Crosscutting Concept: Energy and matter
An ExampleMiddle School: Chemical Reactions
How is NGSS different from previous standards?
■Students know all matter is made of atoms, which may combine to form molecules.
5th grade state standard, CA 1998
■Develop a model to describe that matter is made of particles too small to be seen.
5th grade NGSS performance expectation 5-PS1-1
Current state standard NGSS Performance expectation
What does it mean to learn that “matter is made of molecules”?
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Learning Grows Over Time
Learning difficult ideas •Takes time
•Develops as students work on a task that
forces them to synthesize ideas
•Occurs when new and existing knowledge is
linked to previous ideas
•Depends on instruction
Performance Expectations Build Across

Build scientific disposition• Building core ideas, scientific and engineering
practices, and crosscutting concepts across time will support learners building scientific dispositions – think like a scientist
• Knowing when and how to seek and build knowledge • Hmm, what do I need to know? • I wonder if? • I can I explain....?• Do I have enough evidence?
• Students will learn to think like scientists and understand the purpose of evidence
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
NGSS is Different
• Standards expressed as performance expectations
• Combine practices, core ideas, and crosscutting concepts into a single statement of what is to be assessed at the end of grade for K – 5 and grade band for 6 – 8 and 9 – 12.
• They are not instructional strategies or objectives for a lesson.
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Describe Achievement, Not Instruction
Standards articulate a clear vision of the learning goals for students
Standards articulate the student performance at the conclusion of instruction
Standards are NOT a description of curriculum. Standards do NOT dictate instruction.

My dream: engaging students in constructing scientific explanations throughout K – 12
Students of all ages and backgrounds can take part in modeling!
Grades K - 2 Grades 3 - 5 Middle School High School
Use information from observations (firsthand and from media) to construct an evidence-based account for natural phenomena
Use evidence (e.g., measurements, observations, patterns) to construct or support an explanation or design a solution to a problem
Construct a scientific explanation based on valid and reliable evidence obtained from sources (including the students’ own experiments) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future.
Construct and revise an explanation based on valid and reliable evidence obtained from a variety of sources (including students’ own investigations, models, theories, simulations, peer review) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future.

What do students know at this point?• Matter is composed of atoms & molecules in
constant motion.• Substances can exist in solid, liquid, and
gaseous states.• Substances have characteristic properties that
help identify substances and distinguish them from one another.
• Solubility, density, and melting point are properties of substances.
• Both baking soda and road salt are soluble in water (determined in a previous investigation).
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Discussion Questions(before the investigation)
• What do you think might happen when you mix substances together with other substances?
• How would you know whether new substances formed?

What happens when I mix substances together?• Activity Sheet 6
• Read Purpose• Follow safety rules • Teacher demonstrates procedure• Students complete Activity Sheet 6
• Observe and Describe• Investigate• Discuss• Observe and Describe• Write an Explanation
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
DISCUSSION
• Talk with your group about what you observed. • Write a scientific explanation to answer the
question:
What happens when I mix substances together?
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Share your explanations with the group.
What are the features of your explanations?
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Scaffolding Scientific Explanation• Scaffolds provide students with support for
completing challenging tasks they normally they could not accomplish only. • Provide structure for complex tasks.
• Making scientific thinking strategies explicit to students can facilitate their use and understanding of these strategies.
• Revealing the underlying and tacit framework of scientific explanation through scaffolds can facilitate students’ explanation construction.
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
What is a scientific explanation?
A discussion/argument of how or why a phenomenon occurs and the conditions and consequences of the observed event
A Framework for a Scientific Explanations
• Claim: a conclusion about a problem. Typically the claim answers a question
• Evidence: scientific data that supports the claim
• Appropriate and sufficient evidence
• Reasoning: a justification that shows why the data counts as evidence to support the claim and includes appropriate scientific principles
• Consider alternative explanations
• Adapted from Toulmin’s model of argumentation

Question
Institute for Collaborative Research in Education, Assessment, and Teaching Environments for STEM
Teacher Background Knowledge
• A chemical reaction occurs between sodium bicarbonate (baking soda) and calcium chloride (road salt).
• sodium bicarbonate(aq) + calcium chloride(aq) sodium
chloride(aq) + calcium carbonate(s) + carbon dioxide(g)
• Sodium chloride in solution plus carbon dioxide gas plus solid calcium carbonate (chalk) forms.
• The water that is added to the sodium chloride and sodium bicarbonate is not involved in the chemical reaction but is necessary to dissolve the calcium chloride and sodium bicarbonate so that they can react together.
