فاعلية التدريس باستخدام استراتيجية بوليا لحل المشكلات الرياضية في تنمية التفكير الإبداعي : دراسة تجريبية على عينة من تلاميذ السنة الرابعة ابتدائي بمدينة ورقلة
The study aimed to investigate the effectiveness of teaching using the Polya strategy to solve mathematical problems in developing creative thinking among fourth year primary pupils in Ouargla (Algeria). The study is done at the primary of Shanine Mordjane at Hei Naser, Ouargla on a sample of pupils of the fourth level primary school, consisting of two study groups with a total of (40) male and female pupils, where one of the two study groups was randomly selected as an experimental group that includes (20) male and female pupils, and the second group was chosen as a control group that includes (20) male and female students, and to collect the study data, three equivalent tests were built to measure creative thinking in mathematics. Each test consists of (12) items that measure the three dimensions of creative thinking (fluency, flexibility and originality). The first test in the pre-measurement was used to achieving the parity of the two study groups in Creative thinking, and the second test was used in the post measurement, with the aim of comparing the control and experimental groups in creative thinking, while the third test was used, in tracer measurement, with the aim of knowing the continuing effect of the Polya strategy on developing creative thinking on the experimental group, the experimental group was taught the problem-solving activity using the Polya strategy to solve mathematical problems, and the control group was taught in the usual way, and the experiment lasted (5) weeks (3) classes per week, and to test the study hypotheses, the Associative Analysis of Variation (ANCOVA) test was used to measure the significance of the differences between the experimental and control groups in creative thinking after applying the Polya strategy, as well as to measure the significance of the differences between males and females of the experimental group in the dimensional measurement of creative thinking. After controlling the effect of the associated (pre) variable, the "T" test of two linked samples was also used to measure the significance of the differences between the post test and the tracer test in the experimental group. In the statistical analysis, we relied on the Statistical Package for Social Sciences (SPSS) program version (21), and the results showed Teaching using the Polya strategy to solve mathematical problems effectively affects the creative thinking of fourth year primary students in Ouargla city, and There are no statistically significant differences in the impact of teaching using the Polya strategy to solve mathematical problems between males and females of the experimental group, and the results of the study were discussed and interpreted in light of the theoretical framework and related studies.
