However, students receive precious few hours of science instruction as it is. There is simply not enough time to present any but the prevailing viewpoint. There are too many minority views and competeing theories in legitimate science to do anything but teach the prevailing view. Also, as most school curricula is designed as college prep, primary and secondary schools should approach science education with the goal of teaching what they need to know to go on to further science education at university. This speaks to a need to teach the basics, and do so in such a way as to be useful later in education.
Despite the exclamations of some supporters of intelligent design/creationism, science and math class is actually one of the least politicized disciplines within the educational establishment. I can't see how a legislative or judicial victory for the intelligent design/creationism movement could improve the situation. Basic science must be taught, not science with a eye taken towards cultural sensitivity. If the intelligent design/creationism movement succeeds politically, this sets a precedent for other non-scientific theories to do the same. Wait until the Raelians, or Scientologists demand to have their "science" taught, as well. Wait until the Council or Islamic-American Relations gets its finger in the pie.
If ID is ever taught in science class, the people who pushed for it will ber horrified.
First of all, the methodology of science will still be taught, exposing the claims of religion to scrutiny.
Second, if we assume that all living things were designed, that would include diseases and parasites. The (not God, of course) designer will be held responsibile for what looks like the work of a psychopathic sadist.
