The unity of knowledge and action is more expensive than practice
"I forget when I hear it, I remember when I see it, I understand it when I do it." This sentence on the wall of the Children's Museum in Washington all tells such a truth - learning is more expensive than knowing, and it is more expensive than doing. The Western Han Dynasty literary scholar Liu Xiang once said: "It is better to hear than to see, and it is better to see than to practice what you see." For thousands of years, many thinkers and educators have always expounded for us an eternal truth: it is better to hear a hundred things than to see them, and it is better to see them than to do one thing, that is, to unite knowledge and action, and to emphasize practice.
In fact, combining hearing with seeing is knowing, how can a person who has no ink spots in his chest make a difference? The ancients often said that "broad-minded and about to take, thick accumulation and thin hair." "If there is no knowledge or knowledge, presumably no matter who it is, there is nowhere to be desired." Mr. Tao Xingzhi, a great people's educator, pointed out the proposition that "action is the rule of knowledge, and knowledge is the success of action." The name "Practice Knowledge" also represents his educational idea of "action-knowledge-re-action". We gain knowledge by observing and hearing. When Qi Baishi learned to paint shrimp, he used to sit by the shrimp pond all day long to watch the dynamics of shrimp; Xu Beihong's "Running Horse Diagram" was the result of his often watching horses in the stables; da Vinci spent two and a half years searching for characters in taverns and markets to observe the appearance of the characters in order to complete "The Last Supper". The examples of these celebrities all enlighten us that if we want to learn and succeed, we must "know" in our stomachs and understand that "knowing" is the premise and basis of "doing". In the teaching process, teachers should study the realm of "when painting bamboo, there is bamboo in the chest", and in the teaching process, the purpose of teachers disseminating knowledge and students mastering knowledge is achieved.
It is not enough to have "knowing", what matters is "doing", it is doing. If there is only knowledge and foresight, but it is only emptiness, then not only will it not be famous, but it will be considered by others as an "empty water bottle", and there is no real talent and practical learning. Xun Zi said, "I have tasted and thought all day long, and it is better to learn what I have learned." Confucius also said: "I taste all day without eating, all day long without sleeping, thinking, useless, it is better to learn." If you just know it, but not do it, I think what you have learned will be stillborn. In order to ensure the accuracy and auspiciousness of his medical skills, Li Shizhen personally went to the deep mountains to take herbs and asked the medicinal farmers about the situation; Xu Xiake, in order to complete his travels, waded through mountains and rivers, traveled through many cities; Balzac personally went to Africa to hunt lions in order to make the characters in the book have lion-like character and perseverance; Tolstoy personally went to the battlefield to observe in order to portray realistic war scenes. All the examples have proved time and again that only by "doing" can we verify what we "hear" and "see"; only when we "do" can we grasp "knowing" in the true sense.
In teaching activities, teachers can participate in extracurricular activities and observe the natural environment to enable students to experience life and experience nature. Think and get, there are two words in the middle is to do. Lazy hands-on practice, only with book knowledge empty discussion, that will only leave people with a laughing stock. In the past, there were Zhao Kuo who talked about soldiers on paper and eventually lost; now there are students who talk about ideals and ultimately have no achievements.
To learn knowledge, we must not only listen and accept knowledge, but also use our eyes, ears, hands, brains and other senses to participate in learning, and realize the unity of smelling, seeing, and doing, so as to achieve the desired effect; the unity of knowledge and action can make the theory real. Only when knowledge and action are integrated can theories be put into practice; only when knowledge and action are integrated can the knowledge learned not become empty dogmatic theories. As teachers who are about to become teachers, we must also practice the spirit of "unity of knowledge and action", only in this way can we become a qualified teacher.
