## The Effect of Training to Strategy of Solving Mathematical Problem on Academic Achievement and Achievement Motivation, Retention the Information Among 10th Grade Students in Government Schools of Jenin

The aim of the present research was to study The effect of training to strategy of solving the mathematical problem on the level of academic Achievement, retention of information and correlation them with Achievement motivation among 10th grade in govemment schools of Jenin in academic year 2000/2001. The present research attempted to answer the following questions. 1. Is there a difference statistical significant (α = 0.05 ) between the level of academic achievement as a result to strategy of solving the mathematical problem? 2. ls there a difference statistical significant (α = 0.05 ) between the level of retention the information as a result to strategy of solving the mathematical problem ? 3. Is there a correlation statistical significant (α = 0.05 ) between the level of academic achievement and achievement motivation ? 4. ls there a correlation statistical significant (α = 0.05 ) between the level of retention the infomiation and achievement motivation ? The purpose of implanting the experiment a random sample from the stubbing which is formed oh male &amp; female students of l0 Grade in govemment schools of` Jenin district. for the year (2000 — 2001). the estimated number of these students was ( 4169 ) distributed on the govemment schools of the district. The size of this sample was ( 479 ) students from both sex distributed in to two groups , group (A) which A included (210 ) students from both sex. And the group (B) included (269) students from both sex. too , which studied the mathematical content in the equation systems unit through using the strategies of solving the mathematical problems. For studying purpose , A test for measuring equivalence between the two groups A &amp; B was used .From research preparing , the truth of the test was assured through shoeing it to thejudges group , where the test reliability index (0.8183). A test was used to obtain an other purpose for measuring the academic achievement and retention the infonnation, and showing to the judges group . According to reliability index ofthe test through using (Guttman) equation. The reliability index reached (0.9371 ). The researcher established Achievement motivation test which included ( 29 ) paragraph distributed on four domains and they are :- Academic ambition level , and tends to success , affection stability ,hard working . The test was showing to a committee of specialistsjudges to be sure of test truth fullness. And According to reliability index ofthe test through using ( Guttman ) equation. The reliability index was reached (0.7528). After implementing the experiment on tests. The points ware registered and treated statistically in order to get recommendations. the results ware as follows: • There are differences of statistical significant (α = 0.05) between the average marks of (A) groups and (B) groups based on academic achievement test that attributed to strategy of solving the mathematical problem . • There are differences of statistical significant (α = 0.05 ) between the average marks (A) groups and (B) groups based on solving the equations of one veritable and solving the system from equations that have more than one variable and attributed to strategy of solving the mathematical problem. • There are differences of statistical significant (α = 0.05 ) between the average marks of (A) groups and (B) groups based on retention the information test that attributed to strategy of solving the mathematical problem • There is a correlation of statistical significant (α = 0.05 ) between the level of academic achievement and achievement motivation . • There is a correlation of statistical significant (α = 0.05 ) between the level of academic achievement and Academic ambition level and tends to success and affection stability and level of working hard. • There is a correlation of statistical significant (α = 0.05 ) between the level of academic achievement and on retention the information. • There is a correlation of statistical significant (α = 0.05 ) between the level of retention the information and Academic ambition level and tends to success and affection stability and level of working hard.
