The successful education of mentally retarded children is to establish a good relationship between teachers and students. A good teacher-student relationship mainly refers to the students' trust in the teacher and the realization that the teacher is a trustworthy person.

Establishing a good teacher-student relationship is based on love. Children with mental retardation are often timid, lonely and inferior because of their own defects and growth experiences, and are unwilling to contact with others. Therefore, teachers should take the initiative to contact children, so that children can feel the kindness and love of teachers in communication and gradually gain trust. Once children trust the teacher, they can listen to the teacher and learn according to the educational goals.

2, choose a clear educational goal, make the education plan of teaching students in accordance with their aptitude:

One advantage of direct contact and common play between teachers and students is that teachers can properly estimate students' existing ability level, so as to formulate personalized education plans for students that can not only reflect children's ability level, development advantages and disadvantages, but also clarify educational priorities and goals.

3, observe and understand the development level of children in all aspects:

This is a necessary condition for making a personalized education plan. The most useful tools to evaluate children's development level are several psychological test scales. Experienced teachers often combine this evaluation with games or other training activities to observe and understand the development level of children in all aspects, so as to clarify the educational goals and priorities and formulate appropriate individual education plans.
