In the 1974 ICR handbook for high-school teachers titled "Scientific Creationism", Morris used the two-model approach to support his argument that creationism could "be taught without reference to the book of Genesis or to other religious literature or to religious doctrines", and in public schools only the "basic scientific creation model" should be taught, rather than biblical creationism which "would open the door to wide interpretations of Genesis" or to non-Christian cosmogonies.
