Extended data:

Open class is an organized, planned and purposeful formal and open course teaching activity for specific groups. The open class has a clear theme and a clear task. In addition to students, leaders and other teachers also participate, which is a good opportunity for teachers to show their teaching level and exchange teaching experience.

As a form of teaching and research, open class has its value of existence and development. There should be original ecology, research and distinctive personality. Under the guidance of principled and methodological teaching comments, open classes can provide a solid step for teachers' professional growth. With the deepening of the implementation of the new curriculum, the education sector not only strives to update the traditional teaching methods that have been formed in compulsory courses, but also actively reflects on the teaching and research methods that have been bubbling for a long time.

For example, a series of teaching and research activities and their processes, such as the compilation of teaching plans, subject research and thesis writing, have been severely criticized, especially the so-called "open classes" which are varied and carefully packaged. Undoubtedly, it is of great positive significance to study the right and wrong of open classes with a rational attitude, especially for the construction of new courses in senior high schools.

Some people look at the teacher's open class this way-neither lecturing nor observing. Even giving lectures or observing classes should be a true demonstration of the teacher's teaching level, rather than just showing the good side of the teacher and hiding problems. The open class that hides the problem is a performance, a show, a trick to fool people, not a teaching. Teachers really want to solve problems in teaching, so open classes should be regarded as an effective way to find problems and solve them centrally.
