applying critical pedagogies to korean education situations

i think korean teachers who are teaching english in public schools in korea has many constraints by the education policies from the Minisry of Education of korea for them to apply critical pedagogies to their own classes. authorities always says " the curriculum here is set. it is proven...this remined me of Nolan in the DEAD POETS SOCIETY.....

as shown above, this is a korean style but i think that despite this situation, Dialogue Method can be applied in this setting. to put this Method in effect, first, teachers have to have open-minded and widened sight for their students. second, they can put this Method if they have good relationship with their students not only in the classroom but also out of the classroom thinking them as a whole -person
respectly.of course, this ,thought, is just considered in a teacher`s competence and duties.
PS:i imagine that if all teachers who teach english in korea be John Keating, students who around us      can be very happy.
