Education controversy over the teaching of intelligent design in public school classrooms, Johnson wrote "What educators in Kansas and elsewhere should be doing is to 'teach the controversy'." In his book Johnson proposed casting the conflicting points of view and agendas as a scholarly controversy. Johnson's usage differs fundamentally and disingenuously from Graff's original use of the concept. While Graff advocated that a comprehensive understanding of what are considered to be "established" concepts must include teaching the debates and conflicts by which they were established, Johnson appropriated the phrase to cast doubt upon the very process and results of the scientific method of establishing knowledge through debate and conflict based on facts determined by experimentation. The phrase was picked up by the Discovery Institute affiliates Stephen C. Meyer, David K. DeWolf, and Mark E. DeForrest in their 1999 article "Teaching the Controversy: Darwinism, Design and the Public School Science Curriculum" published by the Foundation for Thought and Ethics. This foundation also publishes the pseudoscientific intelligent design biology textbook Of Pandas and People suggested as an alternative to mainstream science and biology textbooks in the Critical Analysis of Evolution lesson plans proposed by proponents of the "teach the controversy" campaign. Development of the strategy Comparisons of the drafts of the intelligent design textbook Of Pandas and People before and after the 1987 Edwards v. Aguillard ruling showed that the definition given in the book for "creation science" in pre Edwards drafts is identical to the definition of "intelligent design" in post Edwards drafts; cognates of the word creation—creationism and creationist, which appeared approximately 150 times were deliberately and systematically replaced with the phrase 'intelligent design'; and the changes occurred shortly after the Supreme Court ruled in Edwards that creation science is religious and cannot be taught in public school science classes. The campaign was devised by Stephen C. Meyer and Discovery Institute founder and President Bruce Chapman as a compromise strategy in March 2002. They had come to the realisation that the dispute over intelligent design's (lack of) scientific standing was complicating their efforts to have evolution challenged in the science classroom. This strategy was designed to move the focus onto an approach that stresses open debate and evolution's purported weakness, but does not require students to study intelligent design. The intention was to create doubt over evolution and avoid the question of whether the intelligent designer was God, while giving
