Nowadays, the development of online college education is in full swing, and various online college education platforms have also sprung up. The development of technology has made these online platforms more and more powerful, escorting the continuous development of online education. Colleges and universities, as the main front for the cultivation of high-quality talents in my country, have already introduced large-scale online courses into education and teaching, enriching the teaching content, and expanding the teaching form. In the face of new technical means and abundant online education resources, the teaching quality of online classrooms in colleges and universities is so low, which deserves our further reflection.
