(1) The principle of relying on positive factors and overcoming negative factors. When everyone thought Xiaohui was naughty, the new class teacher did not make a direct conclusion. But after a comprehensive understanding, I told Xiaohui's father that Xiaohui was very smart and wanted to find a place to play his intelligence. This shows that the new head teacher comprehensively analyzes and objectively evaluates the advantages and disadvantages of students from the viewpoint of "one divides into two"

(2) Respect the principle of combining students with strict requirements. In the process of knowing Xiaohui, the class teacher cares about him in life, helps him in his studies, and tries to communicate with him as a friend. This shows that the new class teacher can respect and trust Xiaohui and guide Xiaohui correctly.

③ The principle of combining collective education with individual education. In the process of moral education, educators should be good at organizing and educating students to love the collective, and rely on collective education to educate every student, and at the same time promote the formation and development of the collective through the education of individual students, so as to organically combine collective education with individual education. When organizing collective activities, teachers should pay attention to guiding and changing the collective's views on individuals, strengthen individual education, influence the collective through individual education, enhance the vitality and vitality of the collective, and then improve the collective centripetal force.
