Schools have their own reasons. Such "etiquette" helps students and teachers to realize the "sacredness" of the classroom and to awaken students' awe of knowledge and truth. Start the journey of pursuing truth in such an environmental atmosphere.
University is also a place to pursue "freedom", and the spirit of freedom is also contrary to the mandatory etiquette spirit. Whether to implement the classroom routine of "stand up and be a good teacher" should also be the freedom of teachers and students. There are also some reasons for the conflict with this classroom practice. Opposing teachers and students pursue "dialogue" in the classroom in order to dilute the binary relationship between teachers and students and seek a mixed relationship, which is conducive to equal discussion and relaxed atmosphere in the classroom.
Classroom routines are also rooted in culture, and we have long been infiltrated by the idea of "respecting teachers and attaching importance to teaching". Classroom routine is also the form or embodiment of "respecting teachers and attaching importance to teaching". But in modern times, under the constant influence of western culture, especially since the reform and opening up, our openness has become higher and higher. As an "exotic product" of western culture, universities are bound to be influenced by it most directly and profoundly, and the "rebellion" against classroom conventions is the direct manifestation of this influence.
