الملخص EN

The aim of the research is to identify the effect of the PEC strategy (P.

E.

C.

S) on the achievement of chemistry and to verify this goal, the null hypothesis was formulated: There is no statistically significant difference at the level of significance (0.05) between the average scores of students of the experimental group who are studying according to the PEX strategy (P.

E.

C.

S) and the average score of the students of the control group who are studying according to the usual method of achieving the chemistry subject, ”The research community was represented by the fifth scientific students in the third day preparatory and secondary schools affiliated to Baghdad's Al-Karkh Education, numbering (49) schools distributed in (6) sectors As for the research sample, it was represented by students The fifth scientific bio-grade, the victory numbers for girls were chosen in the intentional way, and two divisions were chosen from the school in a random way to represent one of the experimental group of (35), and the second is the control group of (36) and a statistical equivalence was conducted between the two research groups in some of the variables that the researcher thinks that they affect the results of the research, and for the research tool, an achievement test was prepared that included (40) paragraphs, including (30) objective paragraphs of the multiple choice type of four Alternatives, and (10) article paragraphs, and its sincerity, consistency, difficulty of its paragraphs, the distinguishing strength of it and the effectiveness of the wrong alternatives were confirmed and the results of the research showed the following: " There is a statistically significant difference at the level of significance (0.05) between the average scores of female students of the experimental group who are studying according to the PEX strategy (P.

E.

C.

S ) and the average score of female students of the control group who are studying according to the usual method of obtaining chemistry and in favor of the experimental group".

In light of this, a number of conclusions, recommendations and proposals were reached.
