A proposed electronic program based on the theory of the three T's in the art of persuasion to develop public speaking skills and address common grammatical errors among Al-Azhar secondary school students.

The current research aimed to develop public speaking skills and address common grammatical errors through an electronic program based on the theory of the three T's in the art of persuasion. A list of public speaking skills and a list of lessons with common grammatical errors were reached. For the experimental treatment of the current research, an electronic program was designed, and one group was chosen for the study. The researcher applied the research tools before and after. The research concluded that the performance of the research group improved after applying the electronic program. The research recommends the need to develop the grammar and public speaking course, and the need to use electronic programs in teaching, especially for learners of the Arabic language.
