Curiosity and the CER Framework in Science
Aug 29, 2024
Lecture Notes: Developing Scientific Explanations with CER Framework
Personal Reflection
Speaker mentions not being skilled in cooking, organizing, and crafts.
Emphasis on the importance of a growth mindset.
Improvement noted in video art and audio over years with practice.
Personal strength identified: Curiosity.
Curiosity in Science
Curiosity often diminishes with age; however, it remains vital for scientific inquiry.
Example: Childhood curiosity about turtles in a pond in Texas.
Scientific Inquiry Example
Observation
: Turtles (red-eared sliders) disappear in winter when the pond freezes.
Question
: Where do turtles go during winter? Do they migrate or hibernate?
Initial Observations
:
Turtles are seen sunbathing or laying eggs.
Concern: Turtles need to breathe air and cannot do so if the pond is frozen.
Science Process and Frameworks
Nature of Science Video
: Discusses non-linear scientific processes and planning investigations.
Framework Introduced
: Claim, Evidence, Reasoning (CER).
CER is applicable across subjects, not limited to science.
CER Framework in Detail
Claim
: Statement or conclusion about a problem.
Evidence
: Data collected that supports the claim.
Reasoning
: Explanation of why the evidence supports the claim.
Application Example: Turtle Investigation
Claim
: Red-eared sliders remain in the water and brumate during winter.
Evidence
:
Observations of turtles' inactivity in the pond during winter.
Peer-reviewed research on red-eared sliders and brumation.
Reasoning
:
Observed turtles survive winter in water, aligning with brumation.
Scientific papers confirm physiological changes in brumating turtles.
Importance of Source Evaluation
Emphasis on using factual, peer-reviewed sources for scientific conclusions.
Avoid unreliable sources like personal websites without scientific backing.
Broader Application of CER
CER is not limited to biology; applicable in daily life to evaluate claims.
Encourages critical thinking: Check for evidence and reasoning behind claims.
Conclusion
Encouragement to apply curiosity and CER framework in various aspects of life.
Final reminder to "stay curious" from the Amoeba Sisters.
