I can agree with this statement in part. Because there are children who, despite their differences from others, can learn together with normal healthy children. However, in such a case the teacher should have the skills and necessary knowledge for inclusive education of such children to help them to adapt in lessons and breaks. This kind of learning is called full inclusion.
On the other hand, children with partial inclusion are taught most of the time in a special remedial program. Most often there are separate classrooms or schools with specially trained teachers to help these children with their learning.
It should be noted that inclusion is the only way to a society where children with special needs are not treated as outcasts. Normal children who are educated together with their peers with special needs have more tolerance and empathy. As a result, there is less bullying in these classrooms.
In addition, inclusive education helps children with special needs to acquire social skills, as the example of peers is the best motivation to copy the behavior and strive to replicate the achievements of their peers.
In conclusion, my opinion is that children with special needs should not be completely shielded from the opportunity to learn with healthy peers. However, should not forget that such children need a certain approach and training.
