The second is the influence of social culture. There is a well-known advertising slogan: "which is the excavator technology?" China Shandong is looking for Lan Xiang. " The reason is that TV, Internet and print media are full of violence. After a long period of intense stimulation, even a tiny message will leave a deep impression on the audience's mind. The spoof of this advertisement by netizens undoubtedly played a role in fueling the fire. What lovers' edition, campus edition, historical records edition, Journey to the West edition, Meng Jiangnv edition, etc., are all spread by "evil black" advertisements through the Internet. How can a lying child not get shot? In developing China, demolition sites are everywhere, and "Lan Xiang Technology" is being interpreted every day. How can children who like to imitate not be eager to try?
The third is the feedback from bionics. After studying the structure, function and working principle of organisms, humans transplanted them into artificial engineering. The new technology created by this invention gave birth to bionics. As early as 1840, during the development of the western United States, there appeared excavators that imitated human structures such as big arms, small arms and wrists, and could walk and twist their waists like manipulators. In the early 1980s, in order to solve the problem that the mud in the excavator bucket affects the working efficiency, Academician Ren Luquan of Chinese Academy of Sciences got inspiration from the adhesion of voles, earthworms, dung beetles and other small animals, and invented the mechanical desorption drag reduction touchdown manufacturing technology. When children witness the work of excavators, they will naturally think of their own hands, thus generating motivation for learning. In the process of control, they have penetrated the body between man and machine, and realized the transmission, transformation and processing of information. A manipulator is a mirror image of its own hand and an extension of its own arm. Excavators are invented by imitating the work of human arms. In the game, children learn to bend their arms, dig and twist their backs with excavators, which is the feedback from bionics.
The fourth is the need for expression. Children like playing with sand as much as they like wind and water. Because sand is a low-structure toy, it has become a sharp weapon for children's psychotherapy in recent years, that is, sand table game. It is this characteristic of "free and protected space" that makes sandplay the basis of clinical treatment and the condition of cure and transformation. Children are a weak language group. They can understand some short words and phrases before learning to speak, but it is difficult to express some complex contents completely and accurately, such as special requirements and special ideas. Sandplay can express children's inner world in nonverbal form. Children manipulate "excavators" to dig sand, which is similar to playing sand table games. They shovel, pay and let go, without too many demands and heavy tasks. In addition to the fun of manipulation, they are still talking about their inner world and even venting their emotions, but their content is not the words we hear, but the results of the game we see.
Children like excavator toys, seemingly simple phenomenon, but it reflects a child's world. We should pay more attention to the world, study it, love what it loves and think what it thinks. This should be our educational attitude and action.
