When evaluating the sensitivity of the environment, we should pay attention to the abnormal performance of children. If intellectual development is affected by visual and auditory defects, we should focus on visual and auditory image training. We all know that Miss Sullivan has guided Helen Keller's education. As a girl who is severely blind and deaf, Miss Sullivan pays attention to tactile training and strengthens Helen Keller's sense of things, association and imagination, and has achieved success. As a child with slightly lower intelligence level, tactile training plays a greater and more effective role. At this stage, family education is the focus. Under the warmth of the family, conscious association and imagination training combined with tactile training will show a unique role in correcting and strengthening intelligence.

Attention-focused education needs persistence. Children with low IQ have short concentration time, which will lead to a vicious circle because they have little contact with the outside world. These children will ignore the outside world and lead to self-isolation. Parents should pay attention to their own attitude, and are used to persuading their children to pay attention to the outside world, respond positively to new external stimuli, improve their attention time bit by bit, and strengthen the results of attention through dialogue. This kind of interaction will arouse children's interest in external observation bit by bit.

Language is an important tool to stimulate the development of intelligence, and the training of IQ is inseparable from language. Parents tell stories in childhood, and then children tell them, which is the primary imitation stage of language education; Then look at the picture and speak, that is, through visual signal stimulation, the stimulation result is derived from language, which is very simple and effective intellectual training; Then there is the guidance and planning training during the game. Games are an important link in the development of human intelligence (excluding electronic games). Parents and teachers should leave a play space close to nature for their children, and group games are more exciting and effective. Preview of competition preparation, rapid communication in the competition, instructions and early warning in case of emergency, etc. Are all effective ways to train intelligence.

IQ is closely related to education. If IQ is a person's innate quality, then education is the acquired factor to improve IQ.
