Abstract :

This study aimed to investigate the effect of training on the strategies of mathematical problem solving, for students of the scientific eleventh grade, due their achievements in Nablus governorate. The sample consists of (70) males and (73) females from the scientific eleventh grade at public schools in Nablus governorate. The study was conducted on the first semester of the year 2007/2008. To achieve the study goals, two schools were intentionally chose; males and females schools. In each schools, two sections were selected. The sections were randomly distributed by Closed Lots. In both schools, one of the two sections was determined as an experimental group and the other group was the control group. The researcher designed a training program, to train the two experimental groups on specific strategies for solving mathematical problems. The two control groups was only taught the mathematical content. The researcher conducted a pretest to measure the equivalence between the experimental and the control groups. The pretest was validated and it’s was (0.88). Also the researcher conducted a post test with reliability coefficient equals to (0.91). The purpose of the post test was to examine the study hypotheses at (a= 0.05). The first hypothesis was related to the difference between the means of the experimental and control groups due to group variable. The second hypothesis was related to the difference between the means of the experimental and control groups due to gender variable. The third hypothesis related to the difference between the means of the experimental and control groups due to the interaction between group and gender variables. The other hypotheses were related to the effect of training on problem solving strategies, between the experimental and control groups, for males or females. The study results were : - There are significant differences between the means of the experimental and control groups in the post test, due to the training on problem solving strategies. - There are significant differences between the means of the males experimental and males control groups in the post test. - There are significant differences between the means of the males experimental and females control groups in the post test, in favor of the males experimental group, due to the training on problem solving strategies. - There are significant differences between the means of the females experimental and females control groups in the post test. - There are significant differences between the means of the females experimental and males control groups in the post test, in favor of the females experimental group, due to the training on problem solving strategies. - There are no significant differences between the means of the males and females experimental groups in the post test, due to the training on problem solving strategies. - There are no significant differences between the means of the males and females control groups in the post test. - There are significant differences between the means of the experimental and control groups in the post test, due to gender variable. - There are significant differences between the means of the experimental and control groups in the post test, due to the interaction between gender and group variables. In the light of the study results, the researcher recommended the following recommendations : - The necessity of students training on mathematical problem solving strategies. - Embedding the mathematical problem solving, in the textbooks, through all stages. - Encouraging teachers, to use various strategies in teaching mathematical problem solving.
