First, we all need to realize that all children who may have some other the other difficulties or are not performing well as per their class level are not necessarily be unable to learn. Like other individuals they needs acceptance and motivation with a bit of extra support in developing their skills and abilities upto their potentials. These children can get frustrated and may show the same in different ways.
There are some children that have problems with language development and sociability while some other may have poor attention or hyperactivity. All these problems have direct impact on their learning process. Some other child may not have any other problem but may learn with a slower pace in comparison to the other children of their age. With the children with specific problems we need to work with the students on the basis of clinical symptoms and try to understand their deviation from what we call as normal and should work on skills to shorten the gaps and improve the abilities for independent living in life.
