In can’t help but ask, given your own time frame.
How did the American education system of 1840 falter due to modern 1850 influences and how do we suffer today from the same?
The Prussian school system was based on dull, repetitive tasks, bells, division of cirriculum and time blocs, long-term isolation from daily life, and building groupthink. The building of knowlege has never been the goal of American public education. Many of those who supported implementing it admitted that much.
