I don't know that Filipinos always do this anyway. After all, in the Philippines you go to high school after 6th grade, not 8th, right? And your school year starts in June, not in August or September. (At least, that's how it is with my relatives there...)
There is a lot more emphasis on Filipino things like language and history now than there used to be as well. There's even (at least in my father's opinion) a lot more of a "nationalist" approach to things. He talks about how in his day they used libro instead of aklat which is now more common. He's mentioned other examples of the use of Tagalog words that were never used in his (right after the war) days.
So, I was wondering in what ways you feel that the Filipino educational system does simply follow the US. Is it in the use of English? Anyway, I'd be very interested to hear.
