                                       The education of maladjusted children
1. Maladjusted children are those who are unable to form good relationships with other children because of problems in their character and behaviour. Socially and emotionally maladjusted children are referred for special programs by parents or by teachers when they find it difficult to manage the child at home or in school.
2. Autistic children make a separate part of maladjusted children. Autism is a severe mental illness that affects children and prevents them from communicating with other children or people. Psychiatrists together with social workers and teachers, determine the eligibility of maladjusted and autistic children for special programs. Children with learning disabilities are assessed by psychoeducational diagnosticians, who through educational and psychological diagnostic tests determine the child’s potential for learning and his level of achievement.
3. Psychotherapy and behaviour modification by psychologists, psychiatrists and social workers are generally a part of mental illness, for example depression, by talking to maladjusted children and discussing their problems rather than using drugs or medical treatment. Behaviour modification means the control of behaviour in which desired behaviours are rewarded, and vice versa, undesirable ones are punished. Behaviour modification helps teachers shape individual behaviour toward some desired effect and control behaviour in classrooms.
