What was the American citizenship class taught in schools during the 1940s about, what did they learn?

I am currently reading Reclaiming History by Vincent Bugliosi, in it he mentions a school class called citizenship that Lee Harvey Oswald took in grade one.

What was this class, what did it involve? Is the class still around under a different name or when was it replaced?

Curriculum in American schools is determined at the local level and varies considerably from state to state. Did the book mention a state or district?
