Thanks, @T_aquaticus, for pointing out this potential source of confusion. I updated the description to say, “Designed for home educators and teachers at Christian schools, …” Better?
Because it is explicitly Christian, much of INTEGRATE is not appropriate for use in a public school science classroom (though many of the straight-up science activities would be).
That said, INTEGRATE could be a resource for Christian parents to use with their public school students. It could also be used in a religion course or in a faith-based after-school program.
There are many teachers in public schools who don’t teach evolution because they don’t feel competent to address the concerns of their religious students. These teachers could refer families to INTEGRATE when such concerns arise. Also, many Christian public school teachers may feel uncertain about how evolution fits with their own faith, and may be hesitant to teach it for personal reasons. They might choose to use INTEGRATE for their own edification, even if they aren’t able to use many of the activities in class.
