Parents understood it. But after weighing the pros and cons, they decided that the boy would not be able to study in the inclusive school of general education. Only because it did not function duly. It did not have teachers who understand the diversity of students' abilities, it did not use various forms of teaching, it did not have different ways of assessing students' learning achievements, etc.
And the private school, where everything was fine, is not affordable for parents. The monthly tuition fee is too much for the family. However, specialists there know how to work with Vanya. They told Polina that neurons are the main building blocks of the brain and nerve cells that make up the central nervous system. Connections between neurons help us learn, in fact. Neural connections are formed in early childhood, when parents take care of children, play with them, sing lullabies to them. If the child is raised in the orphanage, their neural connections are destroyed. Therefore, Polina was recommended to develop them and then the boy will study better. Moreover, the mother was given a range of advices. She has never received any advice from school, or boarding school for many months, although she asked for them repeatedly.
