Regarding Content Area Standards, the Textbook Authors Raise the Concern

Regarding content area standards, the textbook authors raise the concern that existing standards:

A) Are too vague and general to be of any use
B) Focus more on socio-emotional development than on cognitive development
C) Have been developed only for academic domains addressed in the No Child Left Behind legislation
D) Are often based on what topics are typically addressed in schools rather than on what knowledge and skills are developmentally appropriate for various age-groups
