الملخص EN

This research aimed to determine the effectiveness of the Polya and Orielly strategies in the achievement, in the science of second grade students is average.

To achieve the research aims, null hypotheses were formulated as the following: 1- There are no statistically significant differences at the level of significance (0.05) among the means scores of the students of the three groups (the first experimental group studied the material according to the Polya strategy and the second experimental group which studied the same material according to the Orielly strategy and the control group that studied the same material accordance to the normal method in achievement test.

The current research was confined on the second grade is average students in average schools in Diwaniyah city center.

The researcher used the experimental design of a research society composed of second is average A school of average Al-Eman was randomly selected to represent the research sample, class (A) was chosen to represent the first experimental group, the second experimental group (B) and (C) the control group, the number of students in the research sample was 78 students, 26 students for the first experimental group, 27 students for the second experimental group and 25 students for the control group.

The equivalence was verified by age, past achievement scores, intelligence test, prior information, and evaluating arguments test.

The researcher built the research tools, which consisted of an achievement test consisting of (30) items multiple choice types, and a test of evaluating arguments consisting of (57) items.

The experiment was applied in the second semester as the beginning of actual teaching (24/2/2019) and the end of actual teaching (24/4/2019).

Results were statistically analyzed using one-way ANOVA and Scheffe Test.

Results showed the following: 1- The first and second experimental groups predominate on the control group in the achievement variable.

2- The school of science and interesting using the Polya and Orielly strategies in teaching science.

3- Guidance and activities to develop the skill of evaluating the arguments at the request.

The researcher also made a number of proposals, including: 1- Study the effect of the Polya and Orielly strategies in the multiple intelligences variable.

1- Studying the impact of the Polya and Orielly strategies in the logical thinking.
