     Is early childhood education really necessary? Early childhood education primarily focuses on learning

through playing to develop the child's physical, sensory (感觉的), communicational and social development.

Early childhood education has become a concern of the government, who pushes poor children to be formally

trained before they are old enough for the kindergarten.

     There are good reasons for the government to push early childhood education. Studies have shown that

orphan children who did not receive good care and education become developmentally delayed causing failure

in school, and even in life. Further studies show that poor children who take part in Head Start programs are

more prepared for school, less likely to end up in Special Education classes, and are less likely to receive public

help or go to jail.

     There are also negative parts of putting a child in formal education programs too early. Time Magazine online

explains that the younger the child, the less his chances of catching up with first-grade work. I have personally

witnessed many children of my generation who went to Head Start programs became frustrated and bored with

school before they finished high school. Yet parents have been sure that the earlier the child starts school, the

better off he or she is, so they push to start childhood education earlier.

     Actually while early formal education of poor children does show great gains in the early elementary years,

studies also show that this head start is really a"false start", as the gains are lost in middle and high school years.

It seems that environment is a bigger factor on life's success than early education. Head Start programs have

not achieved its original goal in closing the achievement gap in poor and middle school children. Perhaps it is

time to find other ways to close that gap.
