اثر استخدام اسلوب مقترح في تدريس مادة الفيزياء في مهارة اجراء التجربة لدى طلاب الصف الرابع العلمي وتطبيقهم

The current research aims to identify (the effect of using a proposed method in teaching physics at the skill of the experiment at the fourth-grade science students and their application of physical principles. The researcher adopted the experimental design of the two groups. The number of students in the research sample reached (59) students of the fourth grade of the secondary school of Ibn al-Fadr under the General Directorate for the education of Diyala / Khalis for the academic year 2016-2017 divided between two divisions, (B) and (B) to represent the experimental group studied in the proposed method. The researcher also constructed the skill test level for the physics subject of (10) paragraphs , an‎d verified the authenticity of its content, presented to a group of specialists , an‎d was applied to a sample to ascertain the veracity of the vertebrae, and was confirmed by the stability of the equation Koderrichardson 20, and was a coefficient of stability (0.72), and was confirmed the strength of discriminatory paragraphs, and the coefficient of difficulty, and the effectiveness of alternatives. The researcher constructed the test applied to the physical principles of physics consisting of (30) objective paragraphs of the type of multiple choice, and verified the validity of its content, presented to a group of specialists, and then applied to a sample survey to ensure the clarity of paragraphs, The coefficient of stability was 0.77, and the discriminant force of its vertebrates, the coefficient of difficulty, and the effectiveness of its substitutions were determined. Using the t-test, with the ends of two independent samples, the null hypothesis was tested.- There is a statistically significant difference between the grades of the experimental group students who studied in the proposed method and the students of the control group who studied in the usual way and for the benefit of the experimental group in the measure of application of the physical principles.- There is a difference of statistical significance between the grades of students of the experimental group who studied in the proposed method and students of the control group who studied in the usual way and for the benefit of the experimental group in the scale of the skill of conducting the experiment.1- Adopting the proposed method in teaching the physics subject and inserting it into curriculum syllabus and teaching methods in the faculties of education.2 - Conduct similar studies in several materials and stages to identify their impact in other variables.
