1, Tao Xingzhi's practice embodies the principle of persuasion. Persuasion principle refers to that in moral education for students, we should be persuasive, convince others by reasoning and improve students' understanding. In the case, when Tao Xingzhi returned to the principal's office, the students were already waiting for training at the door, but when they met, Tao Xingzhi gave him candy and said, this is for you because you came on time and I was late. Tao Xingzhi used his words and deeds to explain the truth, encouraging them to consciously understand the problem and consciously fulfill the moral norms;

2. Tao Xingzhi's practice embodies the principle of combining strict requirements with respect for students. In the process of moral education, educators should not only respect, trust and love students, but also put forward strict requirements for students, and organically combine the two to promote the reasonable requirements of educators to be transformed into students' conscious actions. When Tao Xingzhi saw the students throwing mud at the boys in his class, he stopped the students and asked them to go to the principal's office after school. From this point of view, Tao Xingzhi is strict with students. At the same time, from the whole educational process of Tao Xingzhi, we can see that Tao Xingzhi respects students' personality very much;

3. Tao Xingzhi's practice embodies the principle of combining positive factors with overcoming negative factors. In the process of moral education, we should learn to treat students in two ways and pay attention to tap their own bright spots. In the whole process of education, Tao Xingzhi scolded the students first, and then gave them four pieces of candy, which embodied the principle of developing positive factors and overcoming negative factors.
