The present study aims to investigate the effect of using virtual classrooms (synchronous/asynchronous) through educational platforms (Google Classroom and Google Meet) on some learning outcomes among beginners in breaststroke swimming, by comparing the effectiveness of this modern instructional approach with the traditional method (verbal explanation and demonstration). The researcher adopted the experimental method with two equivalent groups (experimental and control). The sample consisted of (40) third-year students from the Faculty of Physical Education – Zagazig University. The experimental group received an instructional program based on synchronous and asynchronous virtual classrooms, while the control group studied through the traditional method. Pre- and post-tests were applied in both skill performance of breaststroke and cognitive achievement. The results revealed statistically significant differences in favor of the post-tests for both groups, with the experimental group outperforming the control group. This indicates the effectiveness of virtual classrooms in improving both skill performance and cognitive achievement in breaststroke swimming among beginners. The study concluded that employing interactive educational platforms helps reduce the teacher’s workload, enhances learner motivation and engagement, and provides wider opportunities for practice and review according to individual differences. The researcher recommended the wider adoption of virtual classrooms in teaching practical activities in faculties of physical education, in addition to training programs for teachers on how to effectively employ these technological innovations.
