Who Am I? Professor in science education at Michigan State University Director of CREATE for STEM Institute for Collaborative Research in Education, Assessment and Teaching Environments for STEM Taught high school chemistry for 8 years in Milwaukee, Wisconsin Earned my PhD in science education at the University of Iowa My research focuses on designing learning environments to engage teachers and students in doing science (project-based learning) Served as the Lead Writer for the Core Ideas in Physical Science for the Framework for K 12 Science Education and on the Leadership Team of NGSS and as the lead writer for the Physical Science Standards 23

Overview What is a disciplinary core idea? Relationship of core ideas to science and engineering practices The Framework and NGSS Importance of building core ideas across time Supporting students in argumentation Examples of the value of core ideas Questions?? 24

Poll What is the difference between a disciplinary core idea and a science concept? A. Disciplinary core ideas can serve as thinking tools whereas science concepts are much smaller in scope B. Disciplinary core ideas need to develop across time whereas a concept might be taught in a shorter period of time C. There is no difference; a disciplinary core idea is just another way of saying science concept D. Disciplinary core ideas represent several science concepts E. A and B 25

What is a disciplinary core idea? Disciplinary significance Serves as a key organizing concept within a discipline Explanatory power Can be used to explain a variety 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

Value of Using Core Ideas Allows time for: Exploring important concepts and principles Developing integrated understanding Using science and engineering practices Reflecting on the nature of science and scientific knowledge Provides a more coherent way for science to develop across grades K-12

Integrated Understanding Ideas linked together; New and existing knowledge structured around a core idea; Knowledge is useful for problem solving and learning new ideas Chemical change can be Atoms rearrange involves can be Covalent Does not involve ionic Physical change Lose electron Gain electrons Share electron Electron transfer metals Non-metal

A graphical illustration of little, if any, understanding: Learners cannot use ideas for further learning or problem solving Bond breaking Physical change Compounds Chemical change Electrons Atoms

Richard Feynmen (The Feynman Lectures on Physics) If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generation of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis (or the atomic fact, or whatever you wish to call it) that all things are made of atoms little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another.

Chemists typically ask these questions: What is it? How much of it is there? Where might it have come from, where might it go? How fast did it get there? How do I know? The core idea of Matter and Its Interactions gives learners the conceptual tools to respond to these questions. From: Ege, S.N., Coppola, B.P., & Lawton R.J., (1997). The University of Michigan Undergraduate Chemistry Curriculum: Philosophy, Curriculum, and the Nature of Change, Journal of Chemical Education, 74(1), 74-83.

One of the big questions that Matter and Its Interactions allows students to answer is: How can we account for all the different materials in the world, when there are so few elements? In fact, a majority of material in our world is made of C, N, O, H and a few other types of atoms such as Fe, Mg, etc.

Same or Not the Same: An Example Maleic Acid Fumaric Acid Chemical Formula C 4 H 4 O 4 C 4 H 4 O 4 Molecular Mass 116 grams/mole 116 grams/mole Are they the same? Are they different? Do they have the same properties?

How can it be??? Maleic Acid Fumaric Acid Chemical Formula C 4 H 4 O 4 C 4 H 4 O 4 Molecular Mass 116 grams/mole 116 grams/mole Appearance White crystal White Crystal Melting Point 130 139 0 C 287 0 C Solubility in Water Taste Soluble Pungent, repulsive Somewhat soluble Fruity, acidic

Structure and arrangement makes the difference! Fumaric Acid Maleic Acid

Science is not just a body of knowledge that reflects current understanding of the world; it is also a set of practices used to establish, extend, and refine that knowledge. (Framework for K 12 Science Education, NRC, 2012)

How Scientific and Engineering Practices Work Together 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 Engage in science as a set of related practices. Shows how science is really done!

Content and Practice Work Together to Build Understanding Understanding content is inextricably linked to engaging in practices Learning practices are inextricably linked to content! Content and practices codevelop! Practices Crosscutting Concepts Core Ideas

Build Scientific Disposition Building core ideas, scientific and engineering practices, and crosscutting concepts across time will support learning and build 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? Do I have enough evidence? Students will learn to think like scientists and understand the purpose of evidence

Questions? Questions about the definition of disciplinary core ideas Questions about the value of core ideas 42

PS1.A: Structure and Properties of Matter Answers the question: How do particles combine to form the variety of substances one observes? The substructure of atoms determines how they combine and rearrange to form substances. Electrical attractions and repulsions between charged particles (i.e., atomic nuclei and electrons) in matter explain the structure of atoms and the forces between atoms that cause them to form molecules which range in size from two to thousands of atoms. Atoms also combine due to these forces to form extended structures, such as crystals or metals.

PS1.A continued The varied properties of materials can be understood in terms of the atomic and molecular constituents present and the electrical forces within and between them. Within matter, atoms and their constituents are constantly in motion. The arrangement and motion of atoms vary in characteristic ways, depending on the substance and its current state which of course depends on temperature and chemical composition.

What science practices work well with core idea: Structure and Properties of Matter? Developing and using models Planning and carrying out investigations Constructing explanations

Example 1: Middle School Student Pre and Posttest Modeling and PS1 Shayna had a small bottle of Bromine gas. The bottle was closed with a cork. She tied a string to the cork and then placed the bottle inside a larger bottle. She sealed the large bottle shut. (See Figure 1.) Next, Shayna opened the small bottle by pulling the string connected to the cork. Figure 2 shows what happened after the cork of the small bottle was opened. Figure 1 Figure 2 First, draw a model that shows what is happening in this experiment. Second, explain in writing what is happening in your model. Pretest

Example 2: 9 th Grade Physical Science Modeling and PS1 After using a simulation to collect data about the distribution of positive charges in atoms, students were asked what impact this new data would have on their atomic models. Students then revised their models of atoms for a second time, incorporating this new information. Draw a model of an atom with three as an example. A student example, 9 th grade physical science (drawn with computer tools)

Poll How do students learn core ideas? A. Core ideas develop over time as students grapple with more complex situations B. Most core ideas can be developed/taught in a single class period C. Teachers should focus on core ideas in teaching science but not for assessment 49

Core Ideas Develop Over Time Learning is constructed and reworked over time Learning difficult ideas takes time and often comes together as students work on a task that forces them to synthesize ideas Learning is facilitated when new and existing knowledge is structured around the core ideas Developing understanding is dependent on instruction

Progression for Core Idea: Structure and Properties of Matter Highest level By the end of 12 th grade By the end of 8 th grade Atomic Structure Model provides a mechanistic model for explaining why molecules form Atomic/Molecular Model explains properties and diversity of materials By the end of 5 th /6 th grade Particle Model explains phase changes and phases By the end of 2 nd grade Macroscopic Model describes matter Lowest level

Developing Core Ideas through Coherent Instruction Develop core ideas by using coherent instruction Some strategies Activate and use students prior knowledge and experiences Make explicit links to core ideas across time Make explicit how core ideas explain phenomena and solve problems Use and link core ideas to explain phenomena and solve problems

Questions? Questions about PS1.A: Structures and Properties of Matter Questions about ideas developing across time 53

Poll Why are chemical reactions important? A. Chemical reactions are occurring all around us B. Chemical processes underlie many important biological and geophysical phenomena C. Chemical reactions account for the conservations of mass D. All of the above

What happens to the mass of steel wool if you burn it? Initial mass of steel wool: 5.72g

Steel wool burning Make a prediction what would be the mass?

Final mass of steel wool: 6.56g How does this compare to your prediction? What might explain this change? Most students would predict that the mass would decrease.

PS1.B: Chemical Reactions Answers the questions: How do substances combine or change (react) to make new substances? How does one characterize and explain these reactions and make predictions about them? Many substances react chemically with other substances to form new substances with different properties. This change results from the atoms which make up the original substances combining and rearranging to form new substances. Total number of each type of atom is conserved (does not change) in any chemical process, and thus mass does not change either.

Progression for Core Idea: Chemical Reactions Highest level By the end of 12 th grade By the end of 8 th grade By the end of 5 th /6 th grade Atomic Structure Model Chemical processes, their rates, and whether or not energy is stored or released can be understood by the collisions that occur between molecules and the rearrangements of atoms into new molecules. In many situations, a dynamic and reversible reaction determines the numbers of all types of molecules present. Atomic/Molecular Model Substances react chemically. The atoms that make up the original substances are regrouped into different molecules. These new substances have different properties. Atoms are always conserved. Some chemical reactions release energy, others store energy. Descriptive Model When two or more different substances are mixed, a new substance with different properties may be formed. Mass is always conserved. By the end of 2 nd grade Lowest level Descriptive Model Heating or cooling a substance may cause changes.

What science practices work well with core idea: Chemical Reactions? Developing and using models Planning and carrying out investigations Constructing explanations

Example 3: Middle School - Substance and Property Explanation Task Examine the following data table: Density Color Mass Melting Point Liquid 1 0.93 g/cm 3 no color 38 g -98 C Liquid 2 0.79 g/cm 3 no color 38 g 26 C Liquid 3 13.6 g/cm 3 silver 21 g -39 C Liquid 4 0.93 g/cm 3 no color 16 g -98 C

Questions? Questions about PS1.B: Chemical Reactions Questions about how this core idea develops over time Questions about use of practices 62

PS1.C: Nuclear Processes Answers the questions: What forces hold nuclei together and mediate nuclear processes? Why doesn t the nucleus fly apart? Phenomena involving nuclei are important to understand, as they explain the formation and abundance of the elements, radioactivity, the release of energy from the sun and other stars, and the generation of nuclear power. Explaining and predicting nuclear processes involves two additional types of interactions known as strong and weak nuclear interactions. They play a fundamental role in explaining why a nucleus doesn t fly apart.

Conclusions Core ideas explain a variety of phenomena, allow us to solve problems, and learn more Matter and Its Interactions explains how we have such a diversity of material in the world with so few atoms and how we can identify them Matter and Its Interactions are critical ideas that all learners to need to understand 64

Matters and Its interactions provides learners the conceptual tools to respond to these questions: What is it? How much of it is there? Where might it have come from, where might it go? How fast did it get there? How do I know? From: Ege, S.N., Coppola, B.P., & Lawton R.J., (1997).
