    • 1. NATURES OF SCIENCE IN THE LAB: THE CREATE-TEST-USE DISTINCTION David Geelan Original Concept: Frank Jenkins
    • 2. ASSUMPTIONS
      • Instructors teach better and students learn better when they know the rules of the knowledge game
      • Create  test  use reasonably represents a cycle of science and of science education work on each and every concept
      • The nature of science is best viewed as the nature s of science
    • 3. DEFINITION OF SCIENCE
      • Science is the study of the natural world in an attempt to describe, explain, and predict changes and products
      • A goal of science is to create, test, and use (with confidence) a scientific concept
    • 4. CHOICES WHEN PRESENTING A CONCEPT
      • Inductive (creating a concept)
      • Hypothetico-inductive (testing)
      • Hypothetico-deductive (testing)
      • Deductive (using the concept)
    • 5. NATURES OF SCIENCE Lab Type Nature of Science Philosopher of Science Date of Intro. Create Inductive (spec  gen) Francis Bacon 1600s Test Hypothetico-deductive Karl Popper 1930s+ Use Deductive (gen  spec) Aristotle 300s BC
    • 6. EVIDENTIAL BASES Evidential Base Description Laboratory (wet lab) evidence gathered in the laboratory by the students Lab exercise (dry lab) evidence gathered for the students and put into a lab format Computer simulation evidence provided in a computer simulation/animation format Computer video evidence provided in a video format (to be analyzed by students)
    • 7. TESTING SCIENTIFIC CONCEPTS
      • Explanatory Power
      • logical consistency
      • *internal consistency
      • *ext. consistency
      • Descriptive Power
      • theoretical descrip.
      • empirical description
      • Predictive Power
      • the most severe test
      • based upon the concept
      • correct predictions are tested to see if they are verified or falsified
