Paul,
        I am currently doing my student teaching and using your CP text to teach
 my
 classes.  After I read your question the other day, I relayed it to my
cooperating teacher for his opinion.  He has been teaching from your book for
at least the past three years and hasn't had the opportunity to teach the
chapters on relativity during any of those years.  He does agree that it is a
good place to put the chapters, however, he feels it is a bit too advanced for
study at that point in a high school students education.  He much prefers the
way you have included the unit in your college edition of the text, and has
considered using that text when he may purchase new books.  Although this
 optionis possible, he would then exclude portions of that text.  In closing, it
 is
his experience that encouraged me to reply.  His opinion is that the text
may be better geared for the high school student if the relativity chapters
were included at the end of the text much like your college edition.

Responding,    Drew
