CONCEPTUAL FRAMEWORK FOR ENVIRONMENTAL LITERACY LEARNING PROGRESSION Practices Principles Processes in systems MICHIGAN STATE UNIVERSITY Environmental Literacy Research Group
PRACTICES for ENVIRONMENTAL SCIENCE LITERACY (SECTIONS OF TABLE) 1. Inquiry: Learning from experience (not addressed in these papers) Practical and scientific inquiry Developing arguments from evidence 2 and 3. Scientific accounts and applications: Learning from authorities Applying fundamental principles to processes in systems Using scientific models and patterns to explain and predict 4. Using scientific reasoning in responsible citizenship: Reconciling experience, authority, and values Enacting personal agency on environmental issues Reconciling actions or policies with values Understanding and evaluating arguments among experts Environmental Literacy Research Group
ENVIRONMENTAL SCIENCE ACCOUNTS and APPLICATIONS Applying fundamental principles (rows of table)… Structure of systems: nanoscopic, microscopic, macroscopic, large scale Constraints on processes: tracing matter, energy, information Change over time: evolution, multiple causes, feedback loops …to processes in coupled human and natural systems (columns of table) Earth systems: Geosphere, hydrosphere, atmosphere Living systems: Producers, consumers, decomposers Engineered systems: Food, water, energy, transportation, housing
METHODS FOR INVESTIGATING PROGRESSIONS IN STUDENT PERFORMANCES Data sources –Volunteer teachers in working groups –Tests administered to upper elementary, middle, and high school students (available on website) Data analysis –Developing rubrics for open-response questions –Searching for patterns and common themes within and across tests Patterns in accounts of environmental systems (Practices 2 and 3) Patterns in reconciling experience, authority, and values (Practice 4) –Looking for developmental trends Environmental Literacy Research Group
A K-12 LEARNING PROGRESSION TO SUPPORT UNDERSTANDING OF WATER IN THE ENVIRONMENT Beth Covitt & Kristin Gunckel CCMS Knowledge Sharing Institute July 10, 2006 MICHIGAN STATE UNIVERSITY Environmental Literacy Research Group
TRACING WATER IN ENVIRONMENTAL SYSTEMS What to know about “tracing water and other substances” In environmental systems, water usually exists as a mixture When moving through systems, water carries other substances Substances “picked up” by water occur naturally or are result of human action Humans prefer to find and use water with few added substances Humans treat water to minimize harmful substances before/after use Humans return used water to natural systems. Water travels through water cycle and is reused by humans and other species.
PRINCIPLES, PROCESSES and SYSTEMS One facet of water literacy is that… Students can apply FUNDAMENTAL PRINCIPLES (e.g., structure of connected human & natural systems) to PROCESSES IN SYSTEMS (e.g., tracing water & other substances through systems) Examples Groundwater Landfill Contamination Watersheds Ocean Water Human Water System
SOME QUESTIONS NOT ADDRESSED TODAY Watersheds If a pollutant is put into a river at Town C, which towns will be affected? Ocean Water Why can’t we drink clean ocean water without treating it first? How could you make ocean water drinkable? Human Water System Where does water come from before it gets to your house? Where does it go after your house?
GROUNDWATER Draw a picture or explain what it looks like underground where there is water.
Example from High School
LANDFILL CONTAMINATION Can a landfill (garbage dump) cause water pollution in a well?
LANDFILL CONTAMINATION How could a landfill contaminate a well?
KEY FINDINGS: PROGRESSION IN STUDENT UNDERSTANDING OVER TIME Increasing understanding of complexity of systems BUT invisible parts of systems remain invisible Water as mixtures; transport substances Groundwater, watersheds, atmospheric systems Connections between natural & human systems Increasing understanding of need for processes & mechanisms, BUT how these mechanisms work & constraints on processes remain poorly understood. Evaporation, condensation Treating water Increasing awareness of scales, BUT little success in connecting accounts across different levels Macro-Large Scale: Watersheds Environmental Literacy Research Group
DEVELOPING A CARBON CYCLE LEARNING PROGRESSION FOR K-12 MICHIGAN STATE UNIVERSITY Environmental Literacy Research Group
PRINCIPLES, PROCESSES and SYSTEMS Applying fundamental principles… Structure of systems: –atomic-molecular (CO 2 and organic materials), –single-celled and multicellular organisms (producers, consumers, decomposers), –ecosystems Constraints on processes: –Tracing matter: inorganic to organic forms …to processes in coupled human and natural systems Physical Change of Dry Ice Burning Match Losing Weight Plant Growth
TRACING CARBON IN ENVIRONMENTAL SYSTEMS Living systems follow the basic principles of physical and chemical change, including conservation of mass and conservation of atoms Organisms are made mostly of water and organic substances Organic substances consist of molecules with reduced C plus H, O, and a few other elements Virtually all reduced C is created from CO 2 and H 2 O through the process of photosynthesis Virtually all organisms get their energy by oxidizing reduced C compounds in cellular respiration The products of cellular respiration are CO 2 and H 2 O Summary: CO 2 + H 2 O + minerals with N, P, etc. Organic substances + O2 CO 2 + H 2 O + minerals Environmental Literacy Research Group photosynthesis c. respiration
CONSERVING MASS DURING PHYSICAL CHANGE A sample of solid carbon dioxide (dry ice) is placed in a tube and the tube is sealed after all of the air is removed. The tube and solid carbon dioxide weigh 27 grams. The tube is then heated until all of the dry ice evaporates and the tube is filled with carbon dioxide gas. The weight after heating will be: a.less than 26 grams. b.26 grams. c.between 26 and 27 grams. d.27 grams. e.more than 27 grams. Explain the reason for your answer to the previous question. Environmental Literacy Research Group Dry Ice
CHANGE OF STATE “Because going from a solid to a gas, it weighs less” “Because of the law of conservation of mass” Environmental Literacy Research Group Dry Ice
BURNING MATCH Environmental Literacy Research Group What happens to the wood of a match as the match burns? Why does the match lose weight as it burns? ElemMiddleHigh Account for matter (CO 2 and H 2 O)0% 10% Match turns to gases, do not specify gases0%10%5% Account for matter as visible products12.5%15%12.5% Matter is transformed to energy0% 5% Matter disappears, evaporates, disintegrates27.5%47.5%17.5% Physical “visible” changes (turns to smaller pieces)10%20% I don’t know or no response50%7.5%30%
LOSING WEIGHT A person on a diet lost 20 pounds. Some of his fat is gone. What happened to the mass of the fat? “As mass is converted into energy for energy for use, it has to go somewhere. This energy is used to power the body and the fat (now transformed to energy) is spent and no long in the body” “I think it is turned into energy and it also comes out by it turning into water or gas” “it will come out of the large intestine” “the person sweats” Environmental Literacy Research Group

PRINCIPLES, PROCESSES and SYSTEMS The fundamental principle of tracing matter is not being applied by students. Few students understand gases as products or reactants in cellular respiration Students frequently interconvert matter and energy. Many students saw “fat burning” as a process involving “breaking down”, but did not trace it to a chemical process of oxidation into CO 2 and H 2 O in cellular respiration Environmental Literacy Research Group
PLANT GROWTH Environmental Literacy Research Group A small acorn grows into a large oak tree. Where do you think the plant’s increase in weight comes from? ElemMiddleHigh CO 2 in air and H 2 O from roots0% From food or glucose15% 12.5% From air, sun, water, minerals and/or soil12.5%7.5%25% H 2 O from roots15%25%10% Air2.5%0% From the ground or roots12.5%17.5%5% Natural growth7.5%12.5%7.5% Other or Unintelligible10%17.5%32.5% I don’t know or no response25%5%7.5%
PRINCIPLES, PROCESSES and SYSTEMS Environmental Literacy Research Group The fundamental principle of tracing matter is not being applied by students. Few students understand gases as products or reactants in photosynthesis. Students frequently saw water and soil nutrients as the critical source of plant weight.
KEY FINDINGS: FROM YOUNGER TO OLDER STUDENTS, WE SEE PROGRESS… From stories to model-based accounts –Shift from why to how--purposes to mechanisms –BUT lack knowledge of critical parts of systems From macroscopic to hierarchy of systems –Increased awareness of atomic-molecular and large-scale systems –BUT little success in connecting accounts at different levels Increasing awareness of constraints on processes –Increasing awareness of conservation laws –BUT rarely successful in constraint-based reasoning Increasing awareness of “invisible” parts of systems –Increasing detail and complexity –BUT gases, decomposers, connections between human and natural systems remain “invisible”
