That's why I consider native teachers to be the most powerful advantage. At school they insist too much in grammar, that's important, but the foundation is how the language sounds.
I hate movies with original language and subtitles. I've used them with subtitles also in English with great results to learn.
But nothing can replace a teacher that corrects your pronuntiation as you speak and repeats the right sounds as many times as you need.
Also when I'm watching a movie for pleasure, I like to watch and listen, not to read.
I guess the take away is that teaching a whole country a new language takes time and is hard to accelerate.
At least it was according to the constitution but that doesn't mean much. Often laws that modified the 1871 and 1918 constitutions did not change its text but overrode its meaning. Imagine the US constitution but longer you get to hunt down the amendments yourself.
That's tricky. Years ago primary extended from 1st to 8th grades (6 to 14 y.o. aprox.) so English, that started in 6th was primary. Now 6th to 8th have been moved to ESO.
Anyway I just checked with my son and he started in Infantil, so it's really soon.
The real issue is qualification. To really understand and speak English you need to learn pronuntiation properly. And that's the weakest link in our system. Most teachers have no idea how English is really pronounced and wouldn't be able to understand a native speaker to save their lives. It's impossible to learn English from someone that can't understand or speak it.
I believe it was Aguirre that proposed a plan to invite thousands of native speakers to teach English in Madrid. Of course everybody attacked her as usual whatever she says... I don't like her either, but that was a good idea for once.
