This research presents (The Effect of (PDEODE) Strategy in the Second Intermediate Female and Metacognitive skills in chemistry). In order to investigate the aim of this study, one null-hypotheses were designed: There is no statistical difference at (0.05) level between the grade average of the experimental group students who studied chemistry according to (PDEODE) teaching strategy and those who studied the same subject according to the traditional teaching strategy in the meta-cognition skills. This research was applied on the two second grade female students of Al- Rasheed secondary school for females that belongs to administration of Baghdad education \ The first Rusafa for 2016- 2017 educational year , the student sample is of (60) students whom (30) of them is for the experimental group and the other (30) is for the control group. The researcher has prepared the components of the research represented by (assigning the scientific topic from the syllabus according to the Behavioral objectives of each lesson for three chapters (the fourth, the fifth, and the sixth) of second grade secondary school Chemistry book (5th edition , 2014). Those Behavioral objectives were about (200) as well as (32) teaching plan for both groups (the experimental and control group). Research components included the followings Meta-cognitive skills' scale: the researcher designed this scale with (24) items that are equally distributed on the three spaces (planning, observation or control, and Evaluation) , The virtual validity and the structural validity as well as their power of discrimination have been investigated. Moreover, the Reliability Coefficient using internal consistency method (AlphaCronbach's) and it was found to be of (0.86). The researcher depended on the following statistical means: The two-sample T-test (two equal samples), coefficient of discrimination, , alpha Cronbach's coefficient, Pearson correlation coefficient, Coperstatistical, Glass equation, and T-test equation), After grading the answers and processing them statistically by using the statistical package for the social sciences ( SPSS-20), the results were shown as follows: There is a between the two groups (the control and experimental group) in the variable of meta-cognitive skills for the advantage of the experimental group.
