Is high school level math/science being taught well in North America?

1 pointzippy7862 comments

I'm constantly worried whether I should educate my children in school in North America or back home in south-east asia. I'm mostly worried that my kids won't be able to grasp the basic math/science skill as I've seen many students at undergrad level lack proper logic when I was a TA.

I stumbled upon this

The proper solution could be

Question: 30% of 15 = ?

Answer:

30% of 100 = 30

30% of 1 = 30/100

30% of 15 = (30/100)15

           = (3/10)15
 
           = (9/2) = 4.5

The rot logic of creating decimal and not teaching important logic for students who are just learning basics of math bothers me. Wondering if this kind of thing is prevalent ?

How any subject is taught varies significantly from educational system to educational system, and North America doesn't have a single educational system (in the US -- which isn't all of North America -- each state has its own curriculum standards, each school district within each state usually has significant variation within those standards on teaching methods and approaches, and even specific schools and teachers have substantial differences within the policies and practices adopted at the district level. And that's just for public schools, though at least at the lowest levels, the same is true of private schools, which are unlikely to have equivalents of the higher organizational levels.)

No concepts taught here (in NA), move along. If we were to teach people concepts, they may start thinking and turn off their TV. https://en.wikipedia.org/wiki/Humanities#Truth_and_meaning
