1) Yes, that would be, by definition, progressive.
2) I have no idea what you are doing, but my children, along with the rest of the students in their schools, were assessed with "hard evaluations".  Why, sometimes if you did bad they'd hit you with a "hard" rock.
3) No, both are done here.  Although you do realize that all math is abstract, there is no concrete example of math in the universe.  It is a construct of man.
4) You know, you really need to teach somewhere else, presuming you really are a teacher.  There are plenty of places where teachers have plenty of authority.  You just mostly sound like a cynic though.

Just FYI, generally speaking these days school curriculums tend to be the same in 1st world countries, as countries actually do meet and compare notes.  There is some differentiation, but no one's teaching integrals in grade 7.
