أثر اختلاف نمط التعليم المدمج الدوار في تنمية مهارات التصميم الفيزيائي للعدسات الطبية لدى طلاب الدراسات الحرة بالمعهد الفني للبصريات
The objective of the current research is to study the effect of the difference of the rotation blended learning style (Lab-Rotation style Individual-Rotation style) in the development of physical design skills of the medical lenses for free studies students at the Technical Institute of Optics. The research sample consisted of 40 male and female students enrolled in the first grade in the Technical Institute of Optics. The tools included a survey to identify the level of knowledge and skill level associated with the physical design skills of the medical lenses, the achievement test to measure the cognitive aspect associated with the physical design skills of the lenses and the practical performance observation card related to the physical design skills of the medical lenses. The researcher followed the semi-experimental method of experimental design in the processing of statistical data. The results of the study resulted in statistically significant differences between the mean scores of the first (Lab-Rotation) and second (Individual-Rotation) experimental groups in the telemetry on the cognitive test for measuring the cognitive aspect of the physical design skills of the medical lenses for the second experimental group (Individual-Rotation). There were also statistically significant differences between the averages of the experimental groups and the second in the post-measurement of the skill level of the physical design skills of the medical lenses for the second experimental group (Individual-Rotation), Also, there is no statistically significant difference between the intermediate scores of the post-measurement and the follow-up on the cognitive test which measures the cognitive aspect and the note of the practical performance of the physical design skills of the medical lenses in the second experimental group.
