First, a good class should be a meaningful class. For students, at least learn something, and then they can further exercise their abilities, and then develop into a good and positive emotional experience, thus generating a strong need to continue learning. A meaningful class is a solid class, not a lively class.

Second, a good classroom should be an efficient classroom. First, on the other hand, how many students in the class are efficient; The second is the efficiency level. Without efficiency, it is not a good class. An efficient class, that is, a substantial class, is a class with content.

Third, a good classroom should be a living classroom. In other words, a class is not entirely the result of presupposition, but the exchange of true feelings and wisdom between teachers and students in the class. This process has both resource generation and process state generation. This kind of class can be called rich class, which is rich in content and active in many aspects, giving people inspiration.

Fourth, a good class should be a normal class. The value of the classroom lies in producing many new things through the collision and discussion between teachers and students. Such a class is called a prime class. It is necessary to downplay open classes and attend more seminars. No matter who is listening to the class, the teacher should be like everyone else, with only students in mind.

Fifth, having achieved the above points, this class should be a class to be improved. Can't be perfect. It should be a real, unadorned, reflective and reconfigurable course. If it is true, it is flawed. Shortcomings are only real indicators. This class can be called a real class.

"Five realities" is not a perfect evaluation standard, but in the process of pursuing "five realities", teachers have improved their professional level, broadened their horizons and enjoyed all the happiness and wisdom of teaching as a creative process.
