1. Inquiry in theNational Science Education Standards:From Structured Exercises to Guided Learning Experiences toOpen Ended Research John T. Snow College of Geosciences The University of Oklahoma

2. National Research Council, 1996: National Science Education Standards National, not federal A consensus document Reform-oriented, idealistic Controversial  inquiry based Elevates the Earth and Space Sciences to the same level as the Physical and Life Sciences

3. WHY DO WE WANT STUDENTS TO LEARN SCIENCE? • To better appreciate the natural world and the events that occur within it -- requires knowledge and understanding • To lay foundation for careers in the designed world of a modern technological society – may influence career choices; scientific understanding necessary to appreciate “how things work” in the modern world • To contribute in an informed manner to personal, professional, and societal decisions -- requiresdevelopment of “habits of mind”, skills, and experiences applicable to the formulation and solution of problems

4. WHAT IS THE DESIRED OUTCOME OF SCIENCE EDUCATION? A scientifically literate individual who ... … knows relevant parts of the accumulated body of knowledge about the natural world (what scientists know – content “facts”, theories, models); … understands that science is a systematic method for exploring the natural world (how scientists have come to know what they know -- processes, methods, critical thinking; appreciation of risk and uncertainty); and … applies the knowledge and processes of science to the solution of real-world problems (using a scientific approach to solving problems; arguing from data; estimating risk in decisions due to the uncertainty; appreciates and looks for unintended consequences)

5. What is “Inquiry”? • Hard to define precisely, multiple meanings • Elements of scientific inquiry informed, structured, empirical • Stating a problem in a testable fashion • Designing an experiment; collection and critical analysis of data • Reasoning and drawing conclusions from the data; conclusions placed in context of what was previously known • Determining and stating uncertainty • … • Pedagogical inquiry  scientific inquiry + … • Age appropriate • Structured, guided to attain specific learning objectives

6. Can the National Science Education Standards be Implemented without using Inquiry in the Classroom? Yes … … but most of the reform element is lost See “Science as Inquiry” sections in NSES K-4 (p. 121) 5-8 (p. 143) 9-12 (p. 173)

7. Using Inquiry, How Should Science Be Taught? • Shift the focus of instructional activity from teaching to student learning • Curriculum and materials lay out a sequence of guided inquiries, presenting factual material only as needed; assessment tools focus on understanding of processes • Role of the instructor shifts from presentation of rote material to leading/mentoring students through a series of rediscovery experiments

8. “Teaching is nothing more (and nothing less) than a conscious attempt to structure experiences so that desired themes emerge out of guided manipulation of realistic data in compelling situations.” P.J. Gersmehl, 1995

9. Using Inquiry, How Should Science Be Taught? • Emphasize • In-depth understanding of a relative few fundamental elements (balance of “processes” with “facts”  less is indeed more) • Quantitative problem solving • Critical thinking, reasoning from data, and evaluating of new scientific findings • Decision making in a scientific context • Applying understandings to new situations (assessment)

10. Less is More “The test of a successful education is not the amount of knowledge that a pupil takes away from a school, but his appetite to know and his capacity to learn. If the school sends out children with the desire for knowledge and some idea of how to acquire and use it, it will have done its work.” Richard Livingstone, 1941

11. Impediments to Using Inquiry in Teaching Lack of understanding/acceptance of Less is More • Time • Cannot approach “inquiry” as enrichment • Curricula and supporting materials • Teacher Preparation • Traditional focus on grade-level, fact-based learning • Current national desire is to produce well-paid technicians, not scholars, scientists, or artists

12. Illustrative Examples from the NSES - Vignettes Science Olympiad (p. 39) Musical Instruments (p. 47) The Insect and the Spider (p. 80) Weather (p. 130) Weather Instruments (p. 136) Pendulums (p. 148) Funny Water (p. 130) The Egg Drop (p. 162) Fossils (p. 182) Photosynthesis (p. 194) The Solar System (p. 215) See also: Analysis of Scientific Inquiry (p. 202)

13. Further Examples Young students (K – 4): structured exercises – collecting and classifying rocks, leaves, insects around a stream Orient on hands-on work (collect both quantitative and qualitative data) Middle School (5 – 8): guided learning experience – investigating a stream and it’s watershed Emphasize interpretation and application of visual materials (maps, imagery, plots) – reasoning from data Capstone ESS experience at grade 8? High School (9 – 12): open-ended research project – stream water chemistry and relationship to underlying geology and land use in the watershed Establish relevanceof scientific knowledge and way of thinking to the lives of the students, now and in the future Capstone ESS experience at grade 12?; possibility of building on physics, chemistry, biology

14. The Challenge Devising inquiry based curricula and materials that in the available time communicate the essential content and skills required to meet the demands of standardized testing while providing valid research experiences

15. A Few Words About Technology Use technology to complement, supplement, and extend rather than simply replicate • Use technology only where it enhances student learning in the classroom, laboratory, and field • Ingest, assimilation, analysis, and display of large spatial and/or temporal data sets • Imagery to document events • Interactive modeling of the Earth System • “systems thinking” problem solving • “what if games” policy, strategy

16. A Few Recommendations • Classroom, laboratory, and field activities should encourage active inquiry, and illuminate societal issues and the connections between scientific and non-scientific disciplines • Place principles and problem-solving methods in the context of the local environment (rural, urban, …) • Ensure that curriculum materials reflect the diversity of the population, locally, nationally, and globally

19. Key Concepts in the Earth and Space Sciences: • Formation, continuous co-evolution over deep time, present day structure • Processing of energy through the system and recycling of material within the system • Interactions and interconnections between geosphere, atmosphere, hydrosphere, and the biota • Humanity as a element of the System The Challenge: develop age-appropriate inquiry based exercises that foster in students an understanding of the components, evolution, and functioning of the Earth System

20. Charge to Material Developers and Curriculum Builders • Use Earth System Science as a unifying framework to demonstrate the interrelationships between all components of the Earth System and humankind • Implement “best practices” to educate all constituencies, including groups currently under represented in science
