The Effect of (PDEODE) Strategy in the Second Intermediate Female Metacognitive skills in chemistry

Abstract

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  2016-2017educational 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 ( 5^th 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.
