Effective inclusion of students with disabilities in general schools is a social issue, based on the concept of social justice, which provides for the right of all students to equal access to all educational opportunities, regardless of disability or any form of disadvantage. At the same time, students with disabilities face multiple barriers to inclusion, including negative attitudes from teachers. This article reflects some aspects of the research devoted to the formation of positive attitudes of physical education teachers towards children with SEN. We find that inclusive education can be an important tool in changing discriminatory attitudes, but also vice versa - forming an inclusive attitude is a precondition for creating an inclusive environment in schools.
