In the process of design, refinement and selection of the software required for mentally retarded students' education, the characteristics of students should be taken into consideration. Mobile application software can be used as a supplementary material in the education of students who need special education. Many studies reveal that computer assisted programs increase the motivation and concentration time of mentally retarded students and they enjoy studying with mobile devices (Tablets, Smartphones). Apart from ordinary students, mentally retarded students should also be provided with opportunities of technology in their education after developing technology gets into every aspect of the life and is also used in education. In this study, concept teaching based on animation and simulation is intended by making use of technology in the education of mentally retarded students. This process makes a valuable contribution to students in terms of concept learning at schools and rehabilitation centers which facilitate for learning by technology assisted visual programs. This study was conducted with 40 students at four schools of mentally retarded and rehabilitation centers in Sakarya. The evaluation of the data obtained from the application, students who have been learning the concepts of mobile learning tools revealed that they are more successful than those who had learned classical learning methods. According to these results, it can be said that mobile devices make a contribution to concept learning of mentally retarded students.
