The main objective of the current research is to identify the use of video-Based on Tasks to improve Mathematical Practice and support the productive struggle in learning mathematics among teachers of the faculty of Education. The research tools were prepared and adjusted that included a test, score card, and support for productive struggle in mathematics learning. Basically, it was applied to a sample consisting of (20 male and female students) from the third-year students at the Faculty of Education, Tanta University. The study adopted the quasi-experimental curriculum with experimental design (pre-design after one group). In effect, the findings of the research manifested the effectiveness of using video-Based on Tasks to improve mathematical practices and support the productive struggle of student teachers in the faculty of Education. Accordingly, it was recommended to pay attention to international standards for mathematical practices and effective mathematical teaching practices. In addition, it is vital to pay attention to employing video-based on tasks and activating them within the school curriculum.
