The consensus of education professionals about high school curricula in the U.S. is often challenged by right-wing activists. As a result, what children learn is skewed in the name of promoting religious values. There are two main areas which are affected: Sex Education and the teaching of evolution in Biology classes.
In spite of strong evidence that abstinence only sex-ed is ineffective and may even have negative effects, over the past three decades federal funds have been withheld from programs that provide accurate information about contraception, safer sex practices, and sexuality.
Foes of evolution are busy refining their arguments (it’s “intelligent design” today, not “creationism”) but are still as ardently at work as they were at the time of the Scopes Trial of 1925. The biology classroom has become a battleground over the meaning of scientific theory versus religious narrative.
