  1. Basics of the scientific method • Science is concerned with establishing knowledge • Basic research • Applied research • Science is organized to • specify what is problematic, and • specify what constitutes a solution

  2. Non-scientific ways of “knowing” • Tenacity • I’ve always believed it • Authority • The king says so! • Reason • Logic decrees that…. • Common sense • Personal experience How many teeth in the mouth of a horse?

  3. Science’s assumptions • There is order in the universe. • Determinism: For every effect, there is a cause (or more than one cause) • Empiricism: The way to learn about the world is through observation • Parsimony: All other things being equal, simple explanations are better than complex ones

  4. The Goals of Science Get D-PUCk! • Description • Prediction • Understanding • Change

  5. Theory & Hypothesis • Theory: set of propositions about the relationships among a set of concepts • Hypothesis: specific prediction that follows from a theory • Testable (falsifiable) • Best scientific progress made through strong inference
