It seems the public is funding the teaching of nonsense:
Decades of litigation have established that public schools cannot teach creationism or intelligent design. But private schools receiving public subsidies can — and do. A POLITICO review of hundreds of pages of course outlines, textbooks and school websites found that many of these faith-based schools go beyond teaching the biblical story of the six days of creation as literal fact. Their course materials nurture disdain of the secular world, distrust of momentous discoveries and hostility toward mainstream scientists. They often distort basic facts about the scientific method — teaching, for instance, that theories such as evolution are by definition highly speculative because they haven’t been elevated to the status of “scientific law.”
Including about math (via here):
Unlike the “modern math” theorists, who believe that mathematics is a creation of man and thus arbitrary and relative, A Beka Book teaches that the laws of mathematics are a creation of God and thus absolute. Man’s task is to search out and make use of the laws of the universe, both scientific and mathematical.
A Beka Book provides attractive, legible, and workable traditional mathematics texts that are not burdened with modern theories such as set theory. These books have been field-tested, revised, and used successfully for many years, making them classics with up-to-date appeal. Besides training students in the basic skills needed for life, A Beka Book traditional mathematics books teach students to believe in absolutes, to work diligently for right answers, and to see mathematical facts as part of the truth and order built into the real universe.
Ok, so set theory (which was started to make the background of mathematics more rigorous) is bad and obviously so is statistics (since the main parts came out about the same time as set theory and has no absolutes). I wonder what other parts of math they think are bad? Probably probability (no absolutes), but what else?
