I get asked this question from time to time, so my brief response to it is below:
Firstly, it's a GREAT question! And the answer to it is that it is awaiting an organization or private party to create a class or training seminar that is built for the purpose of teaching about this idea, and to then host such a training program while marketing it to potentially interested educators and to supply the demand that exists for such a training.
And it is the position of Abraham Education Services that such a training would be a wholly legitimate endeavor. It is perhaps well known to some that persistent casting of Christian religiosity as something antagonistic within public school curriculum is something that exists, the result of counterculture movements in the 20th century seeing the public education system as a societal institution where their ideas could be proposed and gain traction. Challenges and alternative perspectives to these anti-Christian and anti-religious narratives in public education spaces are wholly legitimate, and indeed, resources to facilitate such a critique could very well be something that schools are in need of. So interested Christian educators could put together curricular material designed to offer alternative perspectives to these anti-Christian (and really anti-God and anti-religious) narratives that exist and offer them to public educators who may be potentially interested in using them and learning more about such perspectives.
Just some ideas for example, a high school literary unit could be created where students read Mere Christianity by CS Lewis, and his theories on life and man's purpose could offer a lens of critique when examined alongside the atheist philosophies of Jean-Paul Sartre, whose philosophies (and those of other like him), influenced highly regarded literary works that are commonly read in schools that propound anti-religionism in the context of the Christian world; such as the works of Albert Camus and Elie Wiesel.
For younger grades maybe a unit could be done focused on the works of Laura Ingalls Wilder where the place of Christianity and religious belief is examined in how it provided strength to a pioneer family forging its way through the many trials of creating a new life on America's frontier. Abraham Education Services supports such projects and advocates that blatantly anti-Christian books such as The Crucible, another commonly read book in schools, be examined through lenses that offer students the chance to see them as advocating an anti-religious agenda while offering alternative perspectives to what religion can offer through the writings of pro-Christian authors such as CS Lewis.
There is nothing unconstitutional about such critical examination of texts, especially in the older grades, and Abraham Education Services advises educators that the beneficial role that Christian belief has played in the formation of Western Civilization is a perspective that should be taught to and offered in public schools to Muslim students as well as others, and we also advise that the writings of pro-Christian authors (such as CS Lewis and others) offer legitimate perspectives for students to be introduced to, while looking at other perspectives as well.
For further information for the interested parties of this concern...
Abraham Education Services does not contract with public school districts, accept or solicit for grants of any kind (governmental, private, or non-profit), nor accept or solicit for donations of any kind. Abraham Education Services operates entirely on a straight forward supply and demand basis for educators who are interested and willing consumers of our offerings. If educators do not register for our programs our programs will come to an end.
Abraham Education Services is also committed to providing educators with resources for understanding extremist ideology and equipping educators with appropriate knowledge needed to combat its poisonous spread.
