So in America, we say that 30 in a class is far far too big. Private schools biggest selling point is that they have tiny classes, usually hovering around 12 students per class.  The biggest complaint that I hear from public school teachers in Korea is how impossible it is to teach effectively to the 30+ students we usually have in a class. TEFL and EPIK training alike focuses on activities geared at far smaller numbers.

The JoongAng Daily seems to feel that the new 29 average in Seoul is too small--they actually made a favorable reference to the classes of 1982 that averaged 62 students per class. Seriously?!
