Not a textbook, but have a look at www.conservapedia.com :
“Conservapedia is a clean and concise resource for those seeking the truth. We do not allow liberal bias to deceive and distort here. Founded initially in November 2006 as a way to educate advanced, college-bound homeschoolers, this resource has grown into a marvelous source of information for students, adults and teachers alike.”
Read the article on the formation of the earth - I’m guessing that this is not too dissimilar to what Christian science books say:

I checked out your link. I don’t see why the ‘Creationists’ View of the Earth’ would be included in a science text. Being simply another viewpoint does not make it science.
