Most educators who are working for children with mental retardation may hav e an interest in effective education methods and strategies to improve latent ability for children with mental retardation . The purpose of this study was to analysis the correlation between intelligibility and the zone of proximal development (ZPD). The story problems with operation which are consisted with twelve questions(six learning and six transfer questions) were developed for the research . The reliability of the test material was obtained through test - retest correlation coefficient by using three different elementary grades. 105 children who are in attendance at the second, third, and fourth grades . The test - retest correlation coefficient was.79. Twenty eleven - to twelve- years mental retarded children who are IQ of 75 to 50. When the ment alretarded children were solving the questions , the number of hint and the amount of time were measured.
In order to test correlation and correlation coefficient, ANOVA and correlation coefficient were utilized to measure two research hypotheses. The result of r elation ships between the intelligibility and the number of hint and the amount of time was not statistically significant at the.01 level. Also, the result of correlation coefficient was not significant ly different. Therefore, this research concluded that the intelligibility is children with mental retardation not related with the ZPD. It means that latent ability of children with mental retardation is related with effective education methods and strategies rather than intelligibility it self.
