When looking at South Korean high schools on the whole, they are insufficiently preparing students for an often learner centered and creative system of education that regularly necessitates students to be self-motivated at universities in and out of Korea. All in all, it is tempting to make the plea that Korean high school education is sound since high school students do comparatively well according to PISA (Program for International Student Assessment) 2006. However, I would be inclined to state the opposite, as you shall see, for reasons which I have based on both experience and research.
As it stands, the Korean secondary system of education is highly successful in preparing students for teacher centered education such as that often used to teach math since the transfer of information is mostly one way, from teacher to student. Nevertheless, this same level of success does not apply to Korean students when they enter more Western styled classroom environments wherein students are expected to take on self reliant roles requiring active and creative personalities in order to attain the best overall results.
