  1. Inquiry for Citizenship—beyond laboratory inquiry Frank Jenkins, PhD Secondary Science Education Centre for Mathematics Science and Technology Education (CMASTE) Centre for Research in Youth Science Teaching and Learning (CRYSTAL Alberta) University of Alberta Edmonton, Canada FJenkins@UAlberta.net, CMASTE

  2. My History for Beyond Inquiry Then(laboratory inquiry) • Processes displayed in laboratory problem solving • Skills, processes, problem solving & nature of science • Create-test-use for kinds of NOS problem solving • Processes required for each of create-test-use • Falsification of hypotheses and predictions Now(beyond laboratory inquiry to media inquiry) • (and then) Multi-perspective view pro and con • Creating criteria list for evaluating claims to knowledge • Testing/Using criteria for evaluating claims to knowledge FJenkins@UAlberta.net, CMASTE

  3. Kinds of Laboratory Inquiry s C-I: create inductively T-HI: test hypothesis T-HD: test prediction U-D: use deductively C - create T - test U - use C-I T-HI T-HD U-D FJenkins@UAlberta.net, CMASTE

  4. CTU & NOS Perspectives • create a concept • inductive reasoning • test & verify hypothesis • hypothetico-inductive • test & verify prediction • hypothetico-deductive • use a concept • deductive reasoning • test & falsify an hypothesis or prediction • The scientific purposes of laboratory work are classified as C, T or U. • C  T  U is a progression for a concept—an increase in certainty/validity/trust. • C  T  U  T eventually leads to falsificationof hypotheses or predictions. FJenkins@UAlberta.net, CMASTE

  5. CTU Lab Reports: Processes FJenkins@UAlberta.net, CMASTE

  6. Lab Unit Plan: CTU & Evid.Bases FJenkins@UAlberta.net, CMASTE

  7. Scientific (NOS) Language Watch your language! • Based upon the evidence gathering here, .... • According to the Bohr model of the atom, …. • The evidence suggests a correlation between …. • The prestigious journal, Science, reports that …. • Only using three samples we found that… • The reliability was high among the class members but …. • The certainty expressed in significant digits is …. Write like a scientist writing for a peer-reviewed journal. Use nature of science language. FJenkins@UAlberta.net, CMASTE

  8. Scientific Language Exercise Take pure science notes • in the left column • [Listen to a science lecture or read primary literature and take standard pure science notes in the left column and nature of science language notes in the right column.] Take NOS notes • in the right column • “Based upon personal peer-reviewed evidence and publications ….” • “Research published in JRST and in Science Education indicates that…” • “If … and … then ….” • “With a high certainty, ….” FJenkins@UAlberta.net, CMASTE

  9. Scientific Attitudes (not attitudes towards science) That which is left after all else is forgotten. • critical-mindedness • suspended judgment • respect for evidence • honesty; objectivity • willingness to change • open-mindedness • questioning attitude • tolerance for uncertainty • curiosity; creativity • appreciation for beauty, unity, and complexity • perseverance Also see: • Technological attitudes • Societal attitudes in STS monograph. FJenkins@UAlberta.net, CMASTE

  10. (Adapted) Primary Literature Learning Science Students learn science by reading primary literature by adaptation of: • language; conceptual level; sentence structure • examples; analogies • amount and level of mathematics • length of article Learning About Science • by adaptation of: • names for experimental designs, procedures, materials and skills • the presentation of counter arguments • quantitative expressions of (un)certainty • reliability & validity arguments FJenkins@UAlberta.net, CMASTE

  11. Creating & Testing My Claim • Education and science primary research literature • Daily Edmonton Journal including Sunday Reader • Nutrition Action Health Newsletter by Centre for Science in Public Interest (a magazine) • Climate Cover-up by James Hoggan (a book) • Wingnuts by John Avlon (a book) • The Best American Science Writing by Groopman • What the Dog Saw by Malcolm Gladwell (a book) • The Demon-Haunted World by Carl Sagan (a book) FJenkins@UAlberta.net, CMASTE

  12. Contexts: Inquiry for Citizenship Source of claims • newspaper articles • magazine articles • lobbying literature • radio and TV news • primary research literature (peer-reviewed) • textbook and classroom language/talk (yours?) Types of claims • medical research • MS liberation treatment • alternative medicine • candling; aromatherapy • environmental research • Oil sands development • claims of the paranormal • water witching FJenkins@UAlberta.net, CMASTE

  13. Health claims to evaluate health claims • drug efficacy • surgery efficacy • alternative medicine • naturopathic; chiropractic • aromatherapy; acupuncture • herbal or magnetic therapy • faith-healing; hair growth • emergency wait-times • surgery-wait-time deaths FJenkins@UAlberta.net, CMASTE

  14. Environmental claims to evaluate environmental claims • Athabasca River water • global warming • oil sands operation • coal-burning plants • coal-bed methane • wind turbines • high voltage power lines • gasoline automobiles FJenkins@UAlberta.net, CMASTE

  15. Political claims to be evaluated political claims • corporate tax cuts create jobs (or not) • private medicine is more efficient (or not) • snow removal costs money (or not) • higher pay invites more competent politicians (or not) • tough punishment deters crime (or not) FJenkins@UAlberta.net, CMASTE

  16. Paranormal claims to be evaluated paranormal claims • alien abductions; UFOs • big-foot; crop circles • psycho-kinetic powers • channeling; mindreading • fairies; ghosts; visions • astrology; ESP • halo readings • water/gold witching FJenkins@UAlberta.net, CMASTE

  17. Education claims to be evaluated education claims • implicit teaching of NoS is effective (or not) • smaller class-sizes increases achievement (or not) • depth of curriculum is better than breadth (or not) • 60 min periods are better than 80 min periods (or not) • inquiry-based learning increases achievement (or not) FJenkins@UAlberta.net, CMASTE

  18. Nutrition Action byCentre for Science in the Public Interest Quick Studies • Mg and Sudden Death • 88 000 women • 26 years • correlational study • Omega-3s Miss Mark • randomly assigned • 4,800 subjects (60-80 a) • 1 of 4 margarines; 3.5 a • no significant difference • Don’t Just Walk • 260 middle aged • four groups (1 control) • 9 months • quotes other studies • Protein & Carbs • eight country study • 800 adults lost weight • then given either protein or carbs FJenkins@UAlberta.net, CMASTE

  25. Perspectives on an issue • Scientific • Technological • Economic • Environmental • Political • Legal • Ethical • Social • Militaristic • Aesthetic • Mystical • Emotional This can be an exercise involving using newspaper clippings and the create-test-use inquiry cycle, where students create and test the list of perspectives. FJenkins@UAlberta.net, CMASTE

  26. CTU Exercises for Beyond Inquiry Evaluating Claims to K • gather & distribute media clippings • create criteria list (from one or more clippings) • test criteria list (from multiple clippings) • use criteria list to analyze & evaluate claims to K FJenkins@UAlberta.net, CMASTE

  27. CTU Exercises for Beyond Inquiry Evaluating STSE views • gather & distribute media clippings • create perspectives list (from one clipping) • test perspectives list (from multiple clippings) • use perspectives list to analyze & evaluate socio-scientific (STSE) views FJenkins@UAlberta.net, CMASTE

  28. Carl Sagan on School Science • Carl Sagan: • “The whole idea of democratic application of skepticism is that everyone should have the essential tools to effectively and constructively evaluate claims to knowledge.” • Demon Haunted World, p. 76 • “[These tools] are hardly ever mentioned in the schools, even in the presentation of science….” DHW, p. 77 • Personal statement: • We have allowed pure science knowledge to dominate other kinds of knowledge. This expresses our current (not past, and hopefully not future) valuing within curriculum & assessment. FJenkins@UAlberta.net, CMASTE

  29. Thank you Hand-off to you: • How do we create, test & use inquiry-based (NOS) science education in the classroom & laboratory. • How do we create, test and use inquiry (NOS) tools for citizenship. • Consider the potential and persevere with your experience, knowledge and problem solving approach.
