The purpose of education is the overall quality standard and learning standard requirements of all levels of education, and it is the general policy followed by all levels of schools. Training objectives refer to the special requirements put forward by schools at all levels according to their respective nature and tasks. The relationship among teaching objectives, education objectives and training objectives is concrete and abstract. They are interrelated, but they cannot replace each other. The teaching purpose is abstract and macroscopic, the training goal is the concrete expression and special requirement of the educational purpose, and the teaching goal is the concrete realization form of the training goal. Goals and objectives are fundamentally different. The goal can be measured, but the purpose cannot be measured.
