"Taking nature and society as the educational background" is the core curriculum view of life education theory advocated by Mr. Chen Heqin. Literally, this sentence means that nature and society are inexhaustible sources of children's learning. This means that Mr. Chen Heqin opposes locking children in the classroom and studying only books. Children can marvel at the magical charm of nature's creations, and children can also experience the joy of learning in their daily lives. This sentence also contains another meaning: children are holistic and not divided, and children's learning can not be completed by teaching in different subjects. We should teach children to learn systematically and the relationship between nature and society. Or it can be said that children learn through experience, and knowledge and skills cannot "occupy" children.
