One source of confusion about the status of the science or theory of evolution stems from the difference between the "everyday" meaning of the word "theory" and the scientific meaning the word.
Below we list some common misconceptions about the term "theory" and describe a classroom activity that can help students rethink their understanding of this term.

Dear NCSE: I teach 9th grade biology and the principal informed me that in response to the request of a parent, a student in my class has been given permission to opt out of the evolution section.
Nested patterns of shared similarities between species play an important role in testing evolutionary hypotheses. "Homology" is one term used to describe these patterns, but scientists prefer other, more clearly defined terms.

"Eroding Evolution," a new article in the July/August 2008 issue of Church and State, addresses the recently enacted "Science Education Act" in Louisiana, which threatens to open the door for creationism and scientifically unwarranted critiques of evolution to be taught in public school science classes.
"A Teacher on the Front Line as Faith and Science Clash" -- a story on the front page of The New York Times (August 24, 2008) -- examines the creationism/evolution controversy as it plays out in the classroom of David Campbell, a biology teacher in Orange Park, Florida.
A noteworthy new paper reports on a national survey of high school biology teachers concerning the teaching of evolution. According to Michael B.
