If your nine-month-old begins speaking in full sentences, you probably will not tell the child to stop and wait till other nine-month-olds catch up. You would not limit such a child to using nouns because that is as much speech as most nine-month-olds can handle. However, in public or private school that may be the approach some educators use.
It is important to realize that they are not purposely setting out to keep your child from learning, although that might be the effect.
Many educators have never knowingly dealt with a highly gifted child. They do not recognize them, and they do not know how to handle them. Some educators base teaching methods an developmental norms that are inappropriate for highly gifted children. Although they may be willing to make an effort to accommodate these youngsters, they may lack sufficient information or experience and not know what type of effort to make.
When a child enters school already able to do what the teacher intends to teach, there is seldom a variety of mechanisms for teaching that child something else. Even if there were a way to provide time, attention, and an appropriate curriculum, it would be necessary for the teacher to use different teaching methods. Highly gifted children learn not only faster than others, but also differently.
Standard teaching methods take complex subjects and break them into small, simple bits presented one at a time. Highly gifted minds can consume large amounts of information in a single gulp, and they thrive on complexity. Giving these children simple bits of information is like feeding an elephant one blade of grass at a time - he will starve before he even realizes that anyone is trying to feed him.
When forced to work with the methods and pace of a typical school, highly gifted children may look not more capable than their peers, but less capable. Many of their normal characteristics add to this problem.
Their handwriting might be very messy because their hands do not keep pace with their quick minds. Many spell poorly because they read for comprehension and do not see the words as collections of separate letters. When they try to "sound out" a word, their logical spelling of an illogical language results in errors. Most have difficulty with rote memorization, a standard learning method in the early grades.
Lack of Fit
The difficulty with highly gifted children in school may be summarized in three words: they don't fit. Almost all American schools organize groups of children by age. As we have seen, the highly gifted child is many ages. The child's intellectual needs might be years ahead of same-age peers, although the gulf may be larger in some subject areas than in others.
Conclusion
Raising a highly gifted child may be ecstasy, agony and everything between. Adults must perform almost impossible feats of balance - supporting a child's gifts without pushing, valuing without overinvesting, championing without taking over. It is costly, physically and emotionally draining, and intellectually demanding. In the first flush of pride, few parents realize that their task is in many ways similar to the task faced by parents of a child with severe handicaps. Our world does not accommodate differences easily, and it matters little whether the difference is perceived to be a deficit or an overabundance.
We have covered only a few issues in this space, but the most important help you can give your highly gifted child or children can be expressed in a single sentence: Give them a safe home, a refuge where they feel love and genuine acceptance, even of their differences. As adults with a safe home in their background, they can put together lives of productivity and fulfillment.
