SCIENTIFIC THINKING Presented by: Dr. Salem M. Al-Ghamdi Associate Professor of Management King Fahd University of Petroleum and Minerals
Absolute truth Known universal laws & facts Problems understood through formal logic or math Uses deductive logical processes “strong relationship between reasons & conclusions” Use rational thinking Relative truth Unknown laws Problems understood through observation & data collection Uses induction to reach conclusion “weak relationship between reasons & conclusions” Uses scientific thinking Styles of Thinking vs POSITIVIST IMPERCIST Can we combine both induction & deduction in research learning? Fact Induction (Deduction) Hypothesis
What is a Theory? What is a Devil’s triangle? Accuracy A set of systematically interrelated concepts, definitions, and propositions that are advanced to explain and predict phenomena (facts) Theory Simplicity Generalizability
What is the role of Hypothesis? What is a Research Hypothesis? • It guides the direction of the study • It limits what shall be studied and what shall not. • It identifies facts that are relevant and those that are not • It suggests which form of research design is likely to be the most appropriate It is a statement that is simply stated, empirically testable, and has two-variable propositions involving concrete instances. What is a good Hypothesis? • Adequate for its purpose: • Be it a descriptive, explanatory, or correlational • It must be testable • It is simple and require few assumptions
