In recent years, educational interactive recording and broadcasting system has gradually become popular in the field of education. Not only some famous universities, but also many remote areas have begun to introduce educational recording and broadcasting. In my opinion, the function and significance of educational recording and broadcasting mainly focus on the following two points: 1) inheriting high-quality teaching resources. As we all know, education is a long-term plan. In the long-term educational process, a large number of educators, special-grade teachers and famous teachers have emerged, who have made great efforts and sweat for the educational cause of our country? The educational cases, educational methods and educational contents of such teachers are all educational wealth, which can be preserved in the form of recording and broadcasting and become inexhaustible educational wealth. 2) Balanced development of education. High-quality teaching resources, through network means, realize the sharing of high-quality teaching resources regardless of region, time and object, so that underdeveloped areas can also enjoy teaching resources in developed areas, and schools with poor teaching conditions can also enjoy high-quality teaching resources, which is equivalent to indirectly achieving the goal of balanced education.
