LEARNING GOALS
- B. CONCEPT ACQUISITION
- The Raft vs. the Pyramid metaphors for science
- a. The Raft: Every scientific claim is subject to question and reevaluation; we can use the rest of our scientific knowledge to question any one claim at a time, though we cannot question the entire edifice at once.
- b. The Pyramid: Science builds on fixed foundations to ever higher levels of knowledge.
- C. CONCEPT APPLICATION
- Explain and contrast the metaphors of raft vs. pyramid for science
- Identify strengths/weaknesses in Raft & Pyramid metaphors for science
- e.g. Some scientific theories are more central than others, and harder to replace. But all scientific theories are, in principle, open to revision in light of new evidence.
