فاعلية التدريس باستراتيجية (PDEODE) في اكتساب المفاهيم الفيزيائية لدى طلاب الصف الثاني المتوسط

Abstract

The aim of the present research is to know The effectiveness of Teaching strategy (PDEODE)in Acquiring the Physical Concepts for second Intermediate Students, through investigating the following tow hypotheses:There is no difference of statistical marker at level (0,05) between the marks average of the students of the experimental group who were taught according to strategy (PDEODE) and marks of the students of the standard group who were taught according to the usual way to acquire physical concept.The researcher has used experimental design of with the equal groups was chosen for the posttest to acquire the physical concepts, and chose Habib ibn mdaher Intermediate School deliberately, then two sections were selected of originally three sections for the second intermediate students in a random way, the total number of sample members was (60) students, of (30) for the control group who were taught in the usual way, and (30) students for the experimental group who were taught with strategy (PDEODE), The researcher has also rewarded both research groups (the experimental and the control) in many variables, these variables are (temporal age in months, intelligence, mid-year mark in physics, previous information). For making sure of the research goals, the researcher has made tool, a test for acquiring the physical concepts, concepts acquisition test involved (45) items from the multiple choice type according to the classification (concept definition , concept distinguishing, application of concept) physics book for the second intermediate students, concepts acquisition test have been presented to a group of experts to check their validity.The experiment was applied in the second educational semester for the year (2013-2014) with two lessons for each group (experimental and control) and took the experiment (9) weeks and to an educational material in teaching the last four chapters of physics for second intermediate students, and the researcher himself has taught the two groups (experiment and control), and after completing the experiment, the results showed the use of the bag statistical (SPSS -20) and software (Excel) the superiority of the experimental group students who were taught according strategy (PDEODE) on the control group students who were taught according the usual way in each concept acquiring test, and eventually, both zero hypotheses. The researcher recommended using the strategy (PDEODE) in the teaching of physics and suggested that multiple studies related to research the current
