1, "Courier class": Emphasis on specialization, mainly aiming at the problem that weak rural schools and teaching points are short of teachers and unable to offer or fail to offer courses prescribed by the state, taking the form of online characteristic classes or synchronous classes, using the Internet to push appropriate high-quality educational resources according to the teaching progress, helping them to offer courses prescribed by the state, and promoting fair and balanced development of education.
2. "Master class": Emphasis on sharing, mainly aiming at the problems of poor teaching ability and low professional development level of teachers. By setting up an online training community, we will give full play to the demonstration effect of the famous teacher classroom, explore new forms of teaching and research activities under the network environment, promote the level of ordinary teachers with excellent teachers, share the resources of famous teachers in a wider range, and promote the professional development of teachers.
3. "Network Classroom of Famous Schools": Emphasis on openness, mainly aimed at the urgent need to effectively narrow the gap between regions, urban and rural areas and schools. It takes high-quality schools as the main body, systematically and comprehensively promotes the sharing of high-quality educational resources in regional or national scope through online schools and online courses, and meets the needs of students' individualized development and high-quality education.
What is the significance and value of carrying out the three-class teaching? ：
The main purpose of fully implementing the "Three Classrooms" is to smooth the educational gap, so that most second-and third-tier cities, remote areas and rural areas can also enjoy the best quality classroom teaching. And the three classes, in essence, are the application of double-qualified classes in three scenarios.
Double-teacher classroom teaching, as its name implies, is a teaching method with strong interaction between teachers and students, in which two teachers jointly complete the teaching activities of a certain subject. It has unique advantages, especially in the face of current curriculum reform.
Its advantages are: first, it is beneficial to realize the complementary advantages among teachers. For example, new and old teachers have complementary advantages, and teachers in different regions have complementary advantages. Second, it is conducive to the close cooperation of teachers. In order to complete the teaching needs of the same class, we should prepare lessons, discuss and optimize the teaching plan together.
