Talking about a good education, I think that, the society has the responsibility to provide it and all the people are the society. for example, teachers, parents, the TV, politicians, you, me...
To have a good education in a country depend of the people of that country.
In Spain we have a bilingual or trilingual education.
I think that is important know languages, but the really important is how to teach languages. so a bilingual or trilingual school is great, but the important thing is the methodology that the teachers use to teach.
And this is the thing that I would change in the present education system.
I think you learn when you make things not when you memorize.
I will avoid exams and books and I will propose things like: investigate, try to do, who we can...
I think that the world has changed a lot and the education only a bit.
To sum up, I think that the Spain state education is great but is our responsibility that gets better.
I propose a methodology change in order to the education change, like the world change.
