Example:

Based on mathematical culture, Qingdao Senior One Mathematics Teaching Seminar was held in Jiaozhou No.2 Middle School. Teacher Liu Caimei of our school successfully opened the Qingdao open class "Solving Function Zero and Equation", which is not only a display of teacher Liu's personal teaching style, but also a wonderful display of the collective wisdom of the senior one math set preparation team. This is a concept class, which adopts problem-solving teaching method and takes "exploring the solution of equations" as the main line, step by step. Teacher Liu is calm in class, and he is willing to take the time to demonstrate the theorem to the students. The whole class pays attention to the infiltration of mathematical culture and thinking methods. When students encounter difficulties, Mr. Liu Can patiently and meticulously guides them, and the dialogue between teachers and students is harmonious and orderly.
