Study Notes

What is the Scientific Method?

A systematic process of acquiring knowledge
Relies on educated assumptions and skepticism
Uses inductive and deductive reasoning
Inductive reasoning uses specific evidence for general conclusions
Deductive reasoning uses a generalization to test specific phenomena
Depends on testable hypotheses
Requires refinement of questions, hypotheses, and testing by experimentation
Results may contribute to the development of a theory

Two Strategies for Acquiring New Knowledge

Inductive
Deductive
Inductive reasoning uses specific evidence from observations/experiments that lead to a general conclusion
Deductive reasoning uses a hypothesis or theory to test specific phenomena or species/situations

Science depends on the Ability to Test Hypotheses

A hypothesis is a tentative explanation for a phenomenon
A hypothesis is a possible answer to a question
A hypothesis is an educated guess
Research hypotheses must be falsifiable and testable
Falsifiable hypotheses have the potential to be rejected as more data accumulates
Testable hypotheses can be tested using repeatable experiments

What is a Theory?

When a hypothesis survives repeated testing by numerous researchers, it may be incorporated into a theory
A theory is a generally accepted explanation of natural phenomena
A theory is supported by a large body of experiments and observations
A theory is always open to further study and revision
A theory represents a larger-scale idea
Confidence in a theory is proportional to the evidence supporting it

What is a Paradigm?

A theoretical framework so successful that future research is carried out within its context
Examples of paradigm shifts
- Theory of Evolution through Natural Selection (Darwin)
- Germ Theory of Disease Transmission (Koch)

Scientific Terminology

Hypothesis
- A tentative explanation for a phenomenon that can be tested in a specific experiment or set of observations
Theory
- Generally accepted explanation of natural phenomena that is supported by a large body of experiments/observations which have been extensively tested
- Theories are open to further study and revision
Paradigm
- Theoretical framework so successful and well confirmed that future research is carried out within its context
