The research aims to investigate the effect of with reciprocal strategy on the achievement of fourth grade fenale students in mathematics . To verify thisain null-hypothesis has been formulated , The sample consisted of fourth practical grade fende students in secondary (HOMS) in Mosul City in (2013-2014) , the total sample are (74), divided into two groups , first of them are (36) and the another are (38) . The researcher uses the equivalence process , (the age, the general average, the degree of mathematics for third-class, the Intelligence) . They have been teaching under the strategy of reciprocal teaching and the another group under the conventional method . The researcher prepared an test in mathematics of (10) variety questions . The level of difficulty and strength of power discrimination of paragraphs and effectiveness of alternatives , were vsel .The implementation of the lessons of the two groups started on Tuesday 01/04/2014 and continued to Thursday 01/05/2014 , where opplid the test on Monday 05/05/2014 , analyzed statistically using between the (t-test) for two independent samples .The results showed that there is statistically significant difference between the average achievement of students for the bereft of experimention group . .
