Spencer was a famous British educator at the end of19th century, and also an advocate of modern western science education thought. He is called "the second Newton in human history" by many people. His thought of happy education comes from thorough analysis and proper control of children's nature. He pointed out: "For a long time, the misunderstanding of education only regards education as the life of an ascetic in a serious class, while ignoring the more meaningful nature education and self-help education for children." And put forward the educational thought of "escaping education and enjoying education", emphasizing that "the education of children should follow psychological laws and conform to the natural order of children's psychological development", revealing the most essential characteristics of science education, which has a milestone role in the development of western science education theory.

Spencer emphasized that the education of children should conform to the natural order of children's psychological development, that is, from simple to complex, from inaccurate to accurate, from concrete to abstract. He is opposed to learning by rote. Spencer's educational core thoughts mainly include the following aspects:

(1) advocates science education and "practical" knowledge. Spencer put forward the excellent viewpoint that scientific knowledge is the most valuable, and formulated a process system with scientific knowledge as the core, striving to make science an indispensable part of education.

(2) Advocate independent education and oppose indoctrination education.

(3) Advocate the education of happiness and interest, and oppose the educational methods that ignore the laws of students' physical and mental development.

Spencer believes that interest is the motivation of children's learning, and geniuses have strong interest guidance in their fields, many of which seem to be meaningless interests. Therefore, there is no good or bad interest. The mistake lies not in children's interest, but in whether parents can guide them correctly. Guide him to acquire new knowledge, new methods and new habits that are beneficial to children. Parents can learn how to guide their children from little Spencer. Throughout the ages, the success of many successful scientists, writers and thinkers began with their childhood hobbies. As Einstein said, "Interest is the best teacher." Follow the path guided by this "teacher" and you may find your own unique life paradise and career destination; Interest is a funny teacher because it unifies "learning" and "playing". Learn by playing and seek "happiness" by playing: interest is an enthusiastic teacher. Can induce children to like and love learning more. What you are interested in. People always think it is the most beautiful and poetic.
