I know of no CS-ED degree, but the University of Maryland offers a combined BS/MS Computer Science degree in 5 years. A good school !
As far as defining a curriculum for K-12 CompSci you can check out Dick Baldwin's site (he teaches Java in Austin, Tex). He has a wealth of "lessons" on his site. Also Stacy Armstrong has a site,
www.apluscompsci.com you might find interesting. His lesson plans have been approved by AP; he provides them to others at a nominal cost and you are allowed to add/delete/modify them as you see fit.
Good luck,
