This study aimed to identify the effectiveness of a proposed educational program based on the Bybee Constructivist Model in improving cognitive achievement and the performance level of some basic basketball skills. The researcher employed the experimental method using a two-group experimental design (experimental and control groups) with pre- and post-measurements, as it was appropriate for the nature of the study. The research population consisted of third-year students at the Faculty of Physical Education for Girls, Zagazig University, during the academic year 2023-2024, totaling 200 students. A random sample of 80 students was selected. Twenty students were assigned to the pilot study, leaving a final sample of 60 students. The participants were divided into two equal groups: an experimental group consisting of 30 students, who were taught using the Bybee Constructivist Model, and a control group consisting of 30 students, who were taught using the traditional method (explanation and demonstration). The results indicated that the experimental group, which was taught using the Bybee Constructivist Model, outperformed the control group, which was taught using the traditional explanation-and-demonstration method, in learning the offensive basketball skills under investigation. Furthermore, the educational program based on the Bybee Constructivist Model contributed positively and effectively to the learning of these offensive basketball skills among the students of the experimental group. The study recommended the implementation of the educational program based on the Bybee Constructivist Model due to its effectiveness in improving the performance level of the basketball skills under investigation. It also recommended applying the Bybee Constructivist learning model to other academic levels because of its positive impact on the learning and performance of basketball skills.
