RESUMO
Aims: The study aimed at identifying effectiveness extent of children songs usage in social adjustment for children with moderate mental retardation
Method: Experimental methodology
Sample: Sample consists of 22 subjects of children with moderate mental retardation who are exposed to integration in Sanan primary school and El-Tabary primary school, Cairo governorate, their age ranges between [7-12] years
Tools: A form of data collection, prepared by the researcher, scale of social adjustment behavior [Abd El-Aziz Al-Shakhs]
Results: there are statistically significant differences between pre and post measure on social adjustment scale and its five dimensions on experimental group in favor of post measure at abstract level that is less than 0.05, as a result, the previous hypothesis is rejected, there are no statistically significant differences between degrees averages of children between experimental group and control group in level of linguistic development on social abstract level 0.445 that is more than 0.05. meaning that there are no differences as a result the previous hypothesis is rejected, there are statistically significant differences between degrees averages of children between experimental group and control group in level of independent occupational performance on scale of social adjustment after applying the program at abstract level of 0.045 as a result the previous hypothesis was rejected in favor of experimental group after post measure, there are statistically significant differences between degrees averages of children between experimental group and control group in level of family roles performance development on scale of social adjustment after applying the program, at abstract level of 0.021, as a result the previous hypothesis was rejected in favor of experimental group after measuring by arithmetic mean 19.6 for 14.7 in favor of control group, there are no statistically significant differences between degrees averages of children between experimental group and control group in level of economical scale after applying the program at abstract level of 0.167, that is more than 0.05, there are statistically significant differences between degrees averages scale of social adjustment after applying the program ay abstract level of 0.02
