The current research amides know the effect of peer teaching strategy on the acquisition of mathematical concepts. To achieve the aim of this research ,the researcher put two null hypotheses .The first ,There is no statistically significant difference at the level of (0.5)between the average of the grades of experimental group that used peer tutoring and that of the control group that used traditional method in the acquisition of some mathematical concepts in the post- test phase according to sex variable. The sample included all special education pupils at Nineveh center for the year 2011/2012. The researcher used the experimental design with two equal groups. The sample consisted of (12) male and female pupils divided in two groups ;the experimental with(6)pupils , (3) males and (3) females who used peer to touring and the other control group of (6) pupils with(3) males and (3)females that used traditional method .Equivalence process in clouded 'time age measured in month and the academic achievement of the parents'. The researcher made a test to acquire mathematical concepts. After doing surface validity ,the test in its final image was adopted. Stability was done using re-test reaching (0.82).The researcher applied the test to measure the acquisition of math metical concepts .After applying the tools, the data were treated statistically .The results showed;
1-There is a statistically significant difference at the level of (0.5)between the means of the experimental group that used peer tutoring and the one of the control group that used traditional method on the acquisition of some mathematical concepts in post test
2- There is no statistically significant difference at the level of (0.5), between the means of the experimental group that used peer to tutoring the average of the control group that used the traditional method in acquiring some mathematical concepts in post test according to sex variable.
Given the results mentioned above, the researcher recommends the use of using peer tarring strategy in the acquisition of mathematical concepts due to its positive effect in developing class interaction between the pupils of special education
The researcher suggests using a similar study to know the effect of using peer tutoring stretchy on learning some materials or initiate a study about the effect of using peer tutoring to ring strategy on some variables like social interaction and the stage.
