Effect of using the (PDEODE) strategy on the achievement of the fifth grade biology students in chemistry

Abstract

The aim of this study is to find out the effect of using the PDEDODE strategy on the achievement of the fifth grade biology students in chemistry. In order to verify the research objectives, the researcher formulated the following zero hypothesis:- There was no statistically significant difference between the average scores of the experimental group and the average score of the students in the control group in the achievement test. In order to verify this hypothesis, the researcher conducted an experiment that took a full course. The following procedures were adopted: The experimental design was chosen from (78) secondary school in Tikrit.) Students. They were randomized to two groups, a pilot that was taught in the three-dimensional education strategy (PDEDODE), and a female teacher. For the sake of the integrity of the research, the researcher rewarded between the two research groups for some variables that may have an effect on the independent variable such as age, intelligence, and grades of the first course.- The scientific material of the research was identified as chapters (3 and 4) of the book chemistry scheduled for the fifth grade biological 2017 -2018. (36) were identified as a behavioral purpose, and the researcher prepared the teaching plans for the two groups.- The researcher prepared the tools for the research where he prepared a test of collection, the number of paragraphs (36) test paragraph of the type of multiple choice.After the experiment was completed, the tests were applied and the results obtained were processed statistically using descriptive statistical methods such as scattering parameters, Centralism and correlation coefficients), and indicative tests include T, as well as statistical means of learning as a square Kai, the results showed:1. The students of the experimental group are superior to the students of the control group in the achievement test.Based on the results, the researcher concluded that the adoption of the PDEDODE strategy in teaching has a positive effect on increasing the achievement of its students. In light of this, the researcher put forward a number of recommendations in addition to a number of suggestions
