This study aims to investigate the effectiveness of using the Seven E’s learning cycle through smartphones in teaching beginners’ finswimming (bi-fins). The importance of the study lies in integrating constructivist learning approaches with the potential of smartphones as modern educational tools, providing a flexible and interactive learning environment that considers individual learner differences. The researcher adopted the experimental method with two groups (experimental and control). The sample consisted of (30) beginners in finswimming (aged 11–13 years) at Al-Waleed Aquatic Sports Club, Mit Ghamr. The experimental group received an instructional program designed according to the Seven E’s learning cycle through a smartphone application, while the control group learned using the traditional method (lecture and demonstration). The results revealed statistically significant differences between pre- and post-tests in finswimming performance for both groups, in favor of the post-tests, with the experimental group showing remarkable superiority. Improvement rates ranged from (72.6% – 131.9%) for the experimental group, compared to (35.9% – 86.3%) for the control group. The study concluded that integrating the constructivist Seven E’s learning cycle with mobile learning via smartphones effectively enhances the skill performance of beginners in finswimming more than traditional teaching methods. The researcher recommended wider adoption of smartphone applications and constructivist models in teaching sports activities and motor skills.
