For children, when learning with the left brain, they must rely on the sea tactics to learn, remember and use flexibly. The mastery of knowledge is divided into four stages: understanding → memory → application → innovation. Most of the talents trained by left brain education stay in the stage of applied knowledge, and innovative talents are rare. Let's take a look at the children in the school at present. No matter whether they study well or not, most of them feel heavy learning burden and pressure. Few children really feel the interest, love and enjoyment of learning. The root of this problem lies in the contradiction between the large amount of learning tasks and the fast progress and the slow, boring and abstract learning characteristics of the left brain. From primary school students to college students, world-weariness and suicides frequently appear in newspapers, which has triggered some calls for reducing the burden on primary and secondary school students. At the same time, some schools with the concept of happy teaching and entertaining education have emerged. However, these have not changed the root of the contradiction, and the children have not really been freed. The reason is that with the rapid development of society, more and more human knowledge is deposited and accumulated, and the standards of talents are getting higher and higher, so the task of children's learning is bound to become heavier and heavier. If children are allowed to learn less, it can be said that it is a retrogression of mankind, which is really not desirable. Then, if we can't start with lowering children's quality standards, we can only make a breakthrough in improving learning methods and improving learning efficiency. The discussion about learning methods used to be very popular. Today, with the research of brain science, people have shifted their attention from learning methods to the fundamental improvement of human intelligence. For example, learning tasks are like mountains, and children are overwhelmed. The solution proposed by the researchers of learning methods is to use the lever principle to give children a lever to pry up the mountain, while the researchers of brain science suggest that children should exercise their brains and do mental gymnastics to make their brains grow stronger, so that children can easily lift the mountain without any tools. The power to move mountains comes from the right brain. If children want to gain this kind of strength, they must carry out appropriate right brain training at the right time, supplemented by harmonious training of the left and right brains. This kind of training is also called right brain development and whole brain development, that is, whole brain education.
