Here's what I learned in history class:
* Civil Rights Movement
* Jim Crow Laws
* Trail of Tears
* Vietnam War
* LA Riots / Rodney King
* Great Depression
* Chicago Fire
* WWII Internment Camps / War Propaganda
* Bay of Pigs in Cuba
* Other failed Coups in South America
* Sherman's March to the Sea
* "The Jungle" (disgusting food)
* Child Labor
* Growth of Monopolies
* Haymarket massacre
What the were YOU doing in school? Mine was mostly a public education, so... plenty of "US mistakes" taught throughout US history from my perspective. Plenty of good and bad in history.
Middle School was mostly basic stuff, borderline propaganda from my memory. (But LA Riots were in fact covered in Middle School, perhaps because they were more "current events" rather than "history" at that point in time). But High School was filled with "TRUTH", in depth analysis and so forth. It was quite eye opening from my perspective. My High School US History class didn't cover "modern US History" however, and stopped in the late 50s. "Modern US History" was an elective at my high school... so my knowledge past the 50s becomes a bit incomplete.
The school cop even ensured a visit to many classes, to describe the rights of citizens in the state. Along the lines of: "In this state, you have the right to know a Cop's identity. If he refuses, take down the number on his car. Here's the police number where you can complain about this stuff". Very specific advice on how to cooperate, and if necessary, complain, about cops.
I know this was unusual and probably specific to the school cop who was assigned to my school. He was African American "and proud of it", to describe his attitude. (may have contributed to his emphasis on teaching citizens rights).
