That seems more conducive to maintaining general interest throughout life, having more choice.
We had one year that was world geography and state history. Half the school year on each one. Other than that, there really wasnt much emphasis on world history outside ancient t civimizations. We spent like a week or so on the Ottoman Empire one year.
I recall having to label a worls map with all the countries with their capitals as part of the semester test that was weighted heavily. If you failed that you failed the semester.
Then in state history you had the same thing with your state county map, the county seat, and the main crop and industry if applicable. Same thing about weight.
I'd always assumed it was like that all across the country, but apparently not since folks don't even know US geography, much less world geography.
