Title: Inquiry for Citizenship


1
Inquiry for Citizenshipbeyond 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

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

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
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 conceptan
    increase in certainty/validity/trust.
  • C ? T ? U ? T eventually leads to falsification
    of hypotheses or predictions.

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.
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, .

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.

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

11

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.

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

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

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.

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.
