How to treat the essence of education after the change and growth of the concept of knowledge?

The process of education is no longer just a process of knowledge transmission and dissemination, but more importantly, it is to cultivate talents through communication, which is the essence of education. (1) Teachers ① Challenge teachers' professional knowledge. Facing the challenges of teachers' higher education, diversification of teachers' sources, integration of teachers' pre-service training and post-service training, scholars of teachers' training objectives and certification of teachers' appointment, what we have to do is to constantly adjust ourselves according to social changes in order to achieve the expected results. 2 cultural literacy. Teachers' lifelong learning is the requirement of the times and the need of teachers' own development. Tao Xingzhi put it well: "Students should study hard if they want to learn well." Only a gentleman who never tires of learning can teach students who never tire of learning. "This points out the importance of teachers' learning, and teachers should regard learning as a long-term and uninterrupted work. Only when you are old can you make progress and innovate. (2) Students ① The impact of knowledge economy and information society. Today's era is experiencing a profound social change: from industrial society to knowledge society. Based on the understanding of the motivation and characteristics of this change, scholars have summarized various related theories from different angles. Learning knowledge only in the classroom can't help students cope with the extensive, complex and changeable social life freely. ② Diversification of learning methods and contents. In the information society, students are indeed more immersed in and compare all kinds of information than in any previous historical period, and are in various contradictions in the process of internalizing knowledge value. Therefore, teaching needs to sort out and promote all kinds of information scientifically and pay more attention to the role of systematic scientific and cultural knowledge. In modern society, we receive a lot of information through ever-changing and ever-increasing channels. In order to process this information accurately, we must have systematic knowledge, intelligence and skills. Scientific knowledge and scientific viewpoint are the universal essence of things and phenomena. Knowledge system and methods can make people make their own explanations for such a large amount of information, and then absorb it in a positive way. ③ Environmental impact. Social changes, national development, family restrictions and educational methods are all very important factors for children's growth under the development of knowledge economy, which determine their development to some extent.
