برنامج قائم على المحاكاة التفاعلية لتنمية المهارات العملية بمقرر إلكترونيات القوى لدى المرحلة الثانوية الصناعية
The present study research aimed at developing of practical skills in power electronics course among industrial third grade secondary school students that were specializing in electrical installations and equipment, a three-years system, through an interactive simulation-based program. The researcher used the quasi-experimental method in which contained two-groups (the control group and the experimental). The study sample consisted of 60 female students. A number of (30) female students from Al-Najah Joint Industrial School were selected as an experimental group (studied using the interactive simulation program), 30 female students from Badr Technical School for Girls were selected as a control group (studied using the traditional Method manner) and the two schools belonged to the Tahrir Educational Administration in Badr, Al-Buhaira Governorate. The researcher prepared the experimental treatment material (a list of practical skills to be developed, the program based on interactive simulation, a teacher guide for using the simulation program), and the measurement tools were prepared, which are (achievement test, practical worksheets, observation cards) and after the study tools were pre-post administrated, the study results showed that there was a statistically significant difference at the level (0.01) between the post tests mean scores of the female students in the achievement test in favor of the experimental group, there was a statistically significant difference at the level (0.01) between the post tests mean scores of the female students in the observation cards in favor of the experimental group. There was a statistically significant difference at the level (0.01) between the pre- post tests mean scores of the female students in the achievement test in favor of the experimental group. There was a statistically significant difference at the level (0.01) between the pre-post tests mean scores of the female students in the in favor of the experimental group. (Published abstract)
