Abstract
Intellectual disability is characterized by substantial limitations in both intellectual functioning and in adaptive behavior. Teaching students with intellectual disability is not an easy task. Use of computer assisted techniques to teach students with intellectual disability is a recent initiative in developing countries. Digital game based learning is an example of computer assisted teaching technique. The objectives of the study were to investigate the use of digital games to develop number concept among students with intellectual disability and to highlight the effectiveness of digital game based learning in attaining number concepts among students with intellectual disability. The researchers used quasi experimental research design (pre-test, post-test control group) to conduct the study. The population of the study consisted of students with intellectual disability at the age of 8 to 16 years having mild to moderate level of I.Q. A sample of 30 students with intellectual disability was taken by using random sampling technique. The students were randomly assigned to two group (15=control group, 15= experimental group). Two (2) mathematical achievement tests were used as an instrument of the study (one for pre-test and one for post). Total 10 sessions were given to teach the number concept to the subjects of experimental group by using digital game as an intervention. The data were analyzed by using IBM version22. The results of independent sample t-test show a significant difference between the pre-test and post -test scores of experimental group after treatment. The study recommended use of digital game to teach the number concepts to children with intellectual disability.
