The use of aids and devices and the importance of using them in the training process is no longer a marginal subject in the process but has become an integral part of its basic components, as the use of various aids and devices makes the training process more effective and positive and has the benefits and functions of several of the most important of which is to build the player's visualization and development and identify tracks correct mobility and other important benefits that work to achieve the greatest possible training efficiency, and the importance of research is to develop the level of good performance through mechanical studies of the movement according to the clear principle that the movement is subject to variables kinma if the performance is performed according to these variables, it shows well. Moreover, the factors that help to develop the movement with less effort and in a mechanical manner that suits that performance and the trainer's and player's knowledge of the movement and its relationship with the mechanical laws and its impact should be identified. The researcher used the experimental method to suit the nature of the problem to be solved. The researcher designed the experimental and control groups with pre- and post-tests i.e. measuring the two groups before and after the experiment. The research sample are practicing students of tennis in the Faculty of Physical Education and Sports Science- University of Diyala for the academic year 2018-20 19 and their number (10) were divided into two experimental and control groups each group consisted of (5) students, through the results that have emerged, the researcher found that the field experience revealed that the educational tool used helps in the training process for the players in the main skill section and has a positive impact on the level and speed of training and that the educational tool used for the backhand is suitable for training different skills in tennis for different age groups as well as showing through field experience, the experimental group was trained using the educational tool.
