Can anyone point me to an online source outlining homework in American schools, from the advent of them in the 1600s to today? That would be awesome. Thanks!
Well firstly I can point you in the direction for homework from the 19th Century.

The library of the uni of Pittsburg has digitised it's collection. This is a collection of schoolbooks from that period, it would include any homework given.
