Teaching is a teacher's understanding or view of teaching, specifically, it is a teacher's understanding of basic issues such as teaching objectives, teaching process and teaching objects. Based on this understanding, teachers determine teaching objectives, choose teaching methods, and determine teachers' attitude towards educational objects in teaching. Education refers to people's views on education and its relationship with other things. Specifically, it is people's understanding of educational elements such as educators, educational objects, educational contents, educational methods and their attributes and relationships, as well as people's views on the relationship between education and other things, and the views on the role, function and purpose of education derived from this.
