4. Questions to Address 1) How did you identify your big ideas? That is, how did you decide what ideas to focus on? 2) How are you treating the relationship between content and practice? 3) What are the implications of learning progressions for writing standards?

5. Question 1 How did you identify your big ideas? That is, how did you decide what ideas to focus on? We need standards that are compact, coherent, and incomplete We need to focus on social utility: Preparing all students for roles as citizens Environmental science literacy as my focus

6. Defining Environmental Science Literacy The required science curriculum should prepare students for roles that all citizens play –Private roles: learner, consumer, worker –Public roles: voter, advocate Key characteristics of informed citizenship –Ability to choose actions consistent with our values –Ability to understand and evaluate arguments from evidence We are developing learning progressions in three strands –Carbon (main focus for today) –Water –Biodiversity

7. Question 2 How are you treating the relationship between content and practice? Content: Students need to be able to “see themselves in the loop diagram.” Practices of environmental science literacy: investigating, accounts, and deciding Using observations, patterns, and models to connect content and practice

8. Goal or Upper Anchor for Content: The Carbon “Loop Diagram” Carbon-transforming processes “loop diagram” (Mohan, et al., 2009 )

9. Practices of Environmentally Literate Citizens Discourses: Communities of practice, identities, values, funds of knowledge Explaining and Predicting (Accounts) What is happening in this situation? What are the likely consequences of different courses of action? Explaining and Predicting (Accounts) What is happening in this situation? What are the likely consequences of different courses of action? Investigating (Inquiry) What is the problem? Who do I trust? What’s the evidence? Investigating (Inquiry) What is the problem? Who do I trust? What’s the evidence? Deciding What will I do? Deciding What will I do?

10. Connecting Knowledge and Practice Inquiry: Learning from data Accounts: Using models

11. Three Points about Content and Practice There is substantial overlap between our practices of environmental science literacy and other lists of practices: –Strands of scientific proficiency in Taking Science to School –Scientific practices in 2009 NAEP Framework The key practices of accounts (explaining and predicting) and inquiry are inseparable from content knowledge and from one another Distinctions among types of knowledge claims— observations, patterns, and models—are essential for defining practices

12. Question 3 What are the implications of learning progressions for writing standards? Implications of the general nature of learning progressions –Conceptual and empirical validation –Telling a developmental story of learning Findings of our research: Key transitions that students need to make –Discourse: Force-dynamic to scientific –Accounts: Explaining and predicting socio-ecological processes at multiple scales –Inquiry: Standards for first-hand and second-hand inquiry

13. Empirical Validation of Learning Progressions: An Iterative Process Framework and assessments are developed concurrently –Develop initial framework –Develop assessments (e.g. written tests, interviews) and/or teaching experiments based on the framework –Use data from assessments and teaching experiments to revise framework –Develop new assessments…. Key question for you: When is this process “finished enough?” We feel pretty confident about carbon, less so about water and biodiversity

14. Another General Point: Different “Stories” of Learning Traditional standards: Accumulation of knowledge –Standards at all levels are scientifically correct facts and skills –Students make progress by learning more facts and more complicated skills Learning progressions: Succession in “conceptual ecologies” –Interconnected and mutually supporting ideas and practices at all levels –Non-canonical ideas and practices can be both useful and important developmental steps –Focus is on sequence of learning rather than age of students

15. Findings from Our Research: Discourse, Accounts, and Inquiry Based on work with fourth grade through college students Applicable more generally than just to carbon cycle

16. Findings about Learning Scientific Discourse Force-dynamic to scientific discourse: learning a fundamentally different way to interpret events in the material world Conceptual transition: from fungible “forces” to enduring entities Epistemological transition: from facts about the world to observations, patterns, and models

17. Contrasts between Force-dynamic and Scientific Discourse Force-dynamic discourse: Actors (e.g., animals, plants, machines) make thing happen with the help of enablers (“needs”) by exerting “forces” –Distinctions among types of enablers and forces are fluid –Actors endure over time, but not the enablers and forces Scientific discourse: Systems are composed of enduring entities (e.g., matter, energy) which change according to laws or principles (e.g., conservation laws) –Clear distinctions among entities –Entities endure over time while systems change

18. Findings about Accounts: Learning about Matter, Energy, and Scale Level 1: Explanations and predictions are based on ideas about actors and enablers at macroscopic scale Levels 2 and 3: –Current: students learn disconnected facts about systems at smaller (microscopic, atomic molecular) and larger (landscape, global) scales –Preferred: students expand awareness to smaller and larger scales in principled ways (focus of our teaching experiments) Level 4: Connected accounts across scales

19. Macroscopic Scale: Grouping and Explaining Carbon-transforming Processes Black: Linking processes that students at all levels can tell us about Red: Lower anchor accounts based on informal discourse Green: Upper anchor accounts based on scientific models

20. Atomic Molecular Scale: Facts vs. Model-based Reasoning High school students learn atomic-molecular facts, such as the equation for cellular respiration. They have a great deal of trouble using those facts as working models: –What happens to the atoms in a person’s fat when he loses weight? (They are burned for energy.) –How do trees grow? (photosynthesis) Where does the mass of trees come from? (water and soil nutrients)

21. Large-scale Systems: Scientific Reasoning about the Carbon Cycle Combustion, cellular respiration Photosynthesis Matter: CO 2, H 2 O, and minerals Matter: Organic matter & O 2 Biosynthesis, digestion, food webs, fossil fuel formation Movement of CO 2, H 2 O, and minerals Energy: Sunlight Energy: Chemical potential energy Energy: Work & heat

22. Informal Reasoning about the Carbon Cycle Animals Plants Carbon dioxide Oxygen Decay Plants NutrientsFood chains Sunlight The oxygen-carbon dioxide cycle Energy sources for plants: sunlight, nutrients, water Energy sources for animals: food, water Decomposers don’t need energy

23. Findings: Inquiry Connections between first-hand inquiry (learning through your own investigations) and second-hand inquiry (learning from claims made by other people or in the media) Key questions: –Who do you trust? –What evidence do you trust? –What arguments do you trust?

24. Changes in Public Opinion Human ActivityNatural Geological Causes April, 200847%34% January, 201034%47% What causes climate change? Note the volatility of public opinion People decide about the science of climate change the same way as they decide about health care legislation Source: Newsweek, March 1, 2010

25. Findings from Our Research How do students make decisions about scientific facts relevant to environmental issues? USUALLY use personal and family knowledge USUALLY use ideas from media and popular culture OFTEN make judgments about bias and self interest in people and organizations making knowledge claims RARELY make use of knowledge they learned in school RARELY make explicit judgments about the scientific quality of evidence or arguments (though our questions on this weren’t great) (Covitt, Tan, Tsurusaki, & Anderson, in revision)

26. What’s Our Goal? Scientific Inquiry and Argument Uncertainty as a core issue for scientific inquiry (Metz, 2004) Scientific position: –Our knowledge of past, present, and future is inevitably uncertain –BUT We can reduce uncertainty, by: Giving authority to arguments from evidence rather than individual people Commitment to rigor in research methods Collective validation through consensus of scientific communities

27. Values in the Science Curriculum The value of scientific knowledge and arguments from evidence should have an explicit role in the curriculum –Scientific knowledge should play an essential role in environmental decisions. In particular, it can help us anticipate the effects of our individual and collective actions. –We should use scientific standards (authority of evidence, rigor in method, collective validation) to judge knowledge claims. We should NOT teach what to do about climate change or other environmental issues in the required science curriculum If people truly understand the effects of their actions, then they are much more likely to make responsible decisions.

28. What’s at Stake? CORE GOAL OF SCIENCE EDUCATION: –Give people the ability to choose between scientific and force-dynamic discourse; don’t leave them without a choice –Make a place for scientific knowledge and arguments from scientific evidence in political discourse and personal decision making. NOTE that this is a different goal from getting people to accept the authority of science. Never in my career has the science curriculum been so important

31. The Keeling Curve as an Example

32. What Does it Mean to “Understand” the Keeling Curve? Content answer: Students should be able to explain the mechanisms and predict the effects of atmospheric change –Yearly cycle –Long-term trend Practice answer: Students should be able to use what they know to act as informed citizens

33. Level 1 Example: Force-dynamic Discourse (4 th grader; American pre-interview: baby growth) Researcher: Do you think the girl’s body uses the food for energy? Watson: Yes. Researcher: Do you know how? Watson: Because the food helps make energy for the girl so then she can like learn how to walk and crawl and stuff. And it will also help the baby so it will be happy, be not mean and stuff. Researcher: Yes, ok. Let’s talk about the next one. You said sleep, right? So say a little bit about that. How is it related to growth? Watson: Because it will make it somehow so you’ll grow. Because that way you will get more energy so you can like run and jump, and jump rope and walk and play. And that’s it. Researcher: Does the baby’s body need sleeping for energy? Watson: Yes. Because then it will be happy and it won’t cry. And it will be able to play and make it so it will eat and stuff. Researcher: What do you think is energy? What energy is like? Watson: I think energy is like, it helps it grow and it helps it so it won’t be crabby, like when you get mad.

34. Level 4: Example: Scientific Discourse (7 th Grader; Post-interview: tree growth) Researcher: So how does a tree use air? Eric: The carbon dioxide in the air contains molecules, atoms, I mean specifically oxygen and carbon, which will store away and break apart to store it and use as food. I: So do you think that the tree also uses water? Eric: Yes. The tree also needs water. All living things do. The water is used to help break apart food so that the tree can have energy. It’s also used to combine parts of the water molecules together with parts of the carbon dioxide in photosynthesis and used as food. Researcher: So, you know, the tree, it begins as a very small plant. So over time, it will grow into a big tree and it will gain a lot of mass. Where does the increased mass come from? Eric: The mass comes from the food that the tree is producing during photosynthesis, which is mostly carbon and hydrogen pieces bonded together and that is then being stored away … … Researcher: So you also talk about energy, light energy. So where does light energy go? Eric: Light energy is, first it’s absorbed through the leaves. It is then converted to a stored energy by combining the hydrogen and carbon atoms into various molecules.

35. Standards that Are Compact, Coherent, and Incomplete 2001: Project 2061 conference on developing curriculum materials based on Benchmarks My conclusion: Too many Benchmarks to teach them all for understanding Question: What is the filter that can help us make wise choices about what to leave out?

36. Social Utility as the Filter My conclusion (based on experience with Benchmarks, NSES, NAEP, Michigan standards): Scientific importance does not work politically as a filter. Every topic in the current standards has passionate advocates who make compelling arguments for its scientific importance Alternate question: Will our nation suffer if most citizens do not understand this?

37. What Happened? Congressional debates about climate change East Anglia E-mails Record snowfall in Washington, DC Rajendra Pachauri consulting IPCC mistake on Himalayan glaciers Note that these affect judgments about people and organizations, but generally not arguments from evidence

38. Possible Consequences Political discourse and personal decisions dominated by different subcultures each constructing their own “reality”—the Prius drivers, the SUV drivers, etc. BUT the Earth’s atmosphere, water systems, and biological communities do not know about political discourse In 50 years we will know for sure who is right and who is wrong Our children and grandchildren will live with the consequences

39. Learning Progressions: Addressing Both the Forest and the Trees “Learning progressions are descriptions of the successively more sophisticated ways of thinking about a topic that can follow one another as students learn about and investigate a topic over a broad span of time.” (NRC, Taking Science to School, 2007)

40. Upper Anchor: Processes in Socio-ecological Systems (Loop Diagram based on LTER Decadal Plan) What is essential scientific knowledge for ALL our citizens? Only a few things, and this is one of them.

41. Informal Interpretation of Heredity and Environment Heredity, determining the essential nature of the organism Environment, determining needs and adaptations Phenotype resulting from “balance of forces” between heredity and environment Heredity and environment both shape the organism by “pulling in different directions.”

42. Scientific Interpretation of Heredity and Environment Genetic resources constrain phenotypic plasticity Phenotype (morphology and behavior) is determined by organism’s response to biological community and non-living environment Notes about scientific model: Heredity and environment act differently Phenotypic response does not affect genetic resources Diversity of genetic resources becomes essential for change
