Educational language is a professional language gradually formed by human beings in the process of education, and it is a language activity used by teachers to impart knowledge, skills and cultivate abilities to students in education. Historically, a preliminary education system appeared in China thousands of years ago. From "preaching to dispel doubts" in ancient times to quality education today, it is inseparable from educational language. Judging from the time of its emergence, the emergence of educational language lags far behind the emergence of human language, and it is gradually formed and developed in educational activities.
The connection between people is maintained by language. With language, people living in society can produce and live together. Teachers are disseminators of human knowledge and morality, and the way they spread knowledge mainly depends on language. Because language is an indispensable tool for communication between people, in all kinds of education in schools, in addition to the necessary educational means, the use of language is one of the most frequent and concise methods. Therefore, a qualified teacher should first have language literacy. In classroom education, teachers use language as a medium to preach, teach and dispel doubts to students, and build a bridge between "teaching" and "learning" through language.
