أثر استخدام استراتيجية التلمذة المعرفية في التفكير الاستدلالي لدى طلاب الصف الثاني المتوسط في مادة الرياضيات

Abstract

      The research aim to identify effect of using cognitive apprenticeship strategy on heuristics thinking of second grade intermediate students in mathematics, the following zero hypothesis were formula to achieve the objective:   

      There is no statistically significant differences at the level of (0.05) between the average scores of experimentalism group taught in the cognitive apprenticeship strategy and the average scores of the control group taught according to the normal method  in the heuristics thinking test.                                                                                

       In order to verify the validity of the two hypothesis , the researchers conducted an experiment lasted for a whole semester. The experiment confined to the students of the second grade of intermediate level. He depended on the partial design experimentalism group and control group with posttest. The school chosen for the experiment is Al-Nahda intermediate school for boys . The sample included (80) students who were subdivided into two subgroups contains (40) students per group. The two groups were matched in variables like (intelligence raven, student achievement in the mathematics subject and test of previous information).The researchers requirements were determine the study content and analyzing them and formulate the behavioral objectives for both groups and building a test for heuristics thinking including (18) items built in the light of the heuristics thinking which included two sub-fields (extrapolative and deductive). Then , the validity.

       The researchers taught the two groups of the study. After the termination of teaching the items according to the plan prepared for the two groups(experimentalism group and control group) the post test was applied and the post test of acquisition test on the sample of the two experimentalism and control groups. The data were analyzed using the (spss) program of socialites .The results after analysis using (t-test) for two independent showed  the excel of experimentalism group over the control group in the variable of the heuristics thinking. Thus, the zero hypothesis of the studying acquisition were rejected .The researchers recommended the necessity of using cognitive apprenticeship strategy in reaching mathematics and also suggested making a similar study on different levels of education .
