No education system is ever 100%. There are always flaws and
loopholes and there will always be a group of people who exploit
them.
Having come from a system where teachers ruled their workplace, i
have to admit my views may be rather biased. However, a more open
classroom may be the way of the future. As children evolve and
become more perceptive at a younger age, one should not stifle
education with passive discipline or silence.
Children should be encouraged to ask questions and express views.
Of course if all the kid asked is 'WHY WHY WHY?', that could drive
teachers up the walls too...
