Increasing advances in information and communication technologies has led to the widespread use of computer technology in today's teaching-learning environments. Therefore, the use of information and communication technology is part of the move towards better use of educational technology in modern schools (Higgins, 1999). In education based on new technologies, visual materials and multimedia software such as animations, dynamic and static graphic images are of great importance (Mayer& Moreno, 2009).
Unlike traditional teaching methods in which students are often confronted with static texts and images, in this way, students are faced with texts and images that are fluent, dynamic and constantly changing quality that gives a new meaning to what is called literacy (Reinking & Chanlin, 1998).Animations, or the rapid display of consecutive images on a computer screen, are a better known type of educational visual material. Animations have three features: First, they are all images that are displayed with certain simulations and movements (Weiss, Knowlton, Mornison, 2002). Secondly, charm and novelty have a special place in animations. This feature makes it easier to understand abstract topics. Finally, animations should be related to the content of the topic (Ploetzner, Lippitsch, Galmbacher, Heuer & Scherrer, 2009). The special features of animation-based methods offer powerful advantages, such as helping to solve learning problems, facilitating the process of constructing meanings, and thus students' academic achievement (Reinking & Chanlin, 1998). Another new area of research in the field of educational multimedia is research on the beneficial effects of dynamic graphic images on the screen. Graphic images are one of the elements of multimedia systems that provide the greatest creativity for learners (Asthana, 2009).
Dynamic graphic images are a combination of shapes that can be selected, moved and even manipulated. These images are designed for learning and can increase the motivation of learners to pay attention to better understanding and help to learn and develop high-level thinking and the formation of concepts (Farhan, 1388).
