• Evidence supporting evolution– Necessary but not sufficient
• Recognizing Misconceptions
• Understanding Students’ Perspectives– Helping Students Understand and Appreciate
the Nature, Processes, and Limits of Science
What Should We Do to Teach About Evolution?

Major Misconceptions• Evolution is a theory about the origin of life.• Evolution is like a climb up a ladder of progress; organisms are
always getting better.• Evolution means that life changed ‘by chance’ (i.e., through strictly
random processes.• Natural selection involves organisms ‘trying’ to adapt.”• Natural selection gives organisms what they ‘need,’ i.e., evolution
is purposeful. • Evolution means struggle in ‘tooth and claw’• Evolution has happened in the past but is no longer taking place.• Other organisms may have evolved, but not humans.• Gaps in the fossil record ‘disprove’ evolution.• Evolution is not science because it is not observable or testable• Evolution is ‘just a theory’ and a ‘theory in crisis’ at that.• Many scientists have rejected evolution as an explanation. • Scientists won’t admit to the public that evolution cannot explain
biodiversity.

Evolution

•To determine which messages have the most impact in terms of clarifying why Intelligent Design/ Creationism should not be taught in public school science classrooms.
•To assess reactions to Science, Evolution and Creationism, and the companion summary brochure.

Strongest messages in both rounds of research
•Invoke the role of evolution in making advances in medicine and curing diseases•The compatibility of religious faith and acceptance of evolution•One’s personal religious viewpoints should not be imposed on public school students
Audience Research Audience Research Selected Findings
A key framing pointScience class should help students to understand how science works and how scientists do their jobs. Evolution is a core scientific principle that is foundational to many areas of science and helps scientists make technological developments, like curing disease.

Glossary of Terms Used inTeaching About the Nature of Science
• Fact: In science, an observation that has been repeatedly confirmed.
• Law: A descriptive generalization about how some aspect of the natural world behaves under stated circumstances.
• Hypothesis: A testable statement about the natural world that can be used to build more complex inferences and explanations.
• Theory: In science, a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.
