Computer Aided Teaching Facility at the Ceylon School
for the Deaf and Blind - Ratmalana

Children who are hearing impaired experience difficulty in speaking. This is not due to any defect in their vocal chords but because they do not hear their own or others' voices and therefore do not have
a reference sound to match.

Computer aided teaching (CAT) is widely used in schools abroad, to great advantage, in teaching the aurally impaired.

Whereas children in the 5-6 year age group have a vocabulary of at least two thousand words, a deaf child who enters school has virtually no reading/ writing vocabulary. It was to redress this deficiency that it was decided to set up the Computer Aided Teaching (CAT) unit at the Ceylon School for the Deaf.
