At present, most families have only one child, and parents generally have the idea of "hope for a child to become a dragon" and "hope for a daughter to become a phoenix". They all want their children to be smarter. The author believes that the so-called smarter is nothing more than a quick reaction, a good memory, and a strong understanding ability, so that the child's brain can be used easily.

Let the left and right brain coordinate with each other and develop in a balanced way.

Contemporary biological and medical research shows that theoretical thinking is mainly located in the left hemisphere, and image thinking is mainly located in the right hemisphere. However, due to the influence of traditional concepts, the teaching content is biased towards traditional education. From curriculum setting, teaching content to education management, it is beneficial to the left brain. For example, in the form of teaching, it is basically language teaching, that is, teachers speak, students listen, and intuitive image thinking is generally ignored. In terms of teaching content, the emphasis is on the process and knowledge of logical derivation by memorizing, ignoring and despising auxiliary means such as observation of objects, experiments and drawings. From the perspective of the selection process, it is generally to see how much they have memorized and how much knowledge can be repeated in words. This excludes people who are good at intuitive thinking in many ways, or people who originally had good right-brain thinking have also been educated and transformed into people who are accustomed to using left-brain thinking. In this way, more attention is paid to the function of the left hemisphere, which has played a major role for a long time, while the development and use of the right hemisphere has been paid insufficient attention, and even suppressed the "motility" of the right hemisphere, so that its potential functions have not been used for a long time. People fully understand. From this, it is not difficult to imagine that if people use the left brain for a long time in work and study, making it overburdened and the right brain idle, it will obviously lead to unbalanced intellectual development, and even the future sustainable development of students. will have adverse consequences. Therefore, the importance and necessity of developing the right brain and developing the left and right brains in a coordinated and balanced manner are obvious.

Use Erhu teaching to develop the right brain world.

In order to better develop the students' right brain world, their intelligence level can be further improved. Using Erhu to teach is a good way. Erhu teaching is a lively and dynamic system project. It always requires the educated to be attentive and sensitive in hearing, to do a variety of complex and active activities with both hands at the same time, and to coordinate the upper body and limbs. In terms of vision, when When you see a note, you must pull it out accurately with both hands, and at the same time you have to look at the note below, otherwise the performance will be intermittent. In particular, the fingering of the left hand, the change of position, kneading and sliding, the strength of the right hand, the stamina, jump, tremor and so on all need to have good coordination and balance control ability. Continuous exercise in this vivid dynamic system will inevitably have a beneficial impact on the healthy growth of people's physiological and psychological thinking. It is also because of this kind of effective training that the neurons in the right brain of a person are always in a state of excitement, stimulating growth, and as time goes by, the new thinking cells of the right brain will continue to increase, making it more powerful than the average person. Sensitive and smart. From this, we can say: Erhu is the most effective means to train students' observation, hearing, memory, sense of rhythm and expressiveness.

Through the teaching of erhu, in addition to completing the basic knowledge and imparting professional skills, it plays a subtle role in strengthening and regulating the functions of the left and right brains. It also has functions that other training cannot replace in many aspects, such as exercising brain power, developing intelligence, cultivating sentiment, cultivating excellent psychological qualities (character, will, temperament), exploring musical potential, and expanding knowledge segments.

We often find this phenomenon in our daily teaching. Some students in kindergarten and middle classes didn't understand anything when they first came to learn erhu. They always cried and hid in their mother's arms. Teach them hand-in-hand, praise and encourage them in a timely manner if they have a little score, and slowly they can perform on stage and take grades exams. Some also won prizes in provincial, municipal and national competitions, and cultural classes were also among the best in the class. Facts have proved that the students who have received this kind of training are quick-witted, and the efficiency of mastering various knowledge is significantly higher than that of other students.

To develop the potential of the right brain needs to start from the baby.

According to the research of medical psychology experts: Early childhood is a sensitive period for the development of human intelligence, and it is the best period for early education. Before the age of four, the development of the nervous system and brain can reach 50% of that of adults, and around the age of eight. It can be developed to 80%, and it can only reach 100% at the age of seventeen. It can be seen that preschool erhu learning is very important for children who are about to enter primary school. The improvement of these qualities will provide them with basic education. It is precisely because the parents realize this, the team in the society is constantly growing, and learning erhu has become a common practice. This has also laid a good foundation for improving the overall quality of our Chinese nation and building a socialist spiritual civilization.
