Dissertação (Mestrado em Matemática em Rede Nacional). Universidade Federal de Goiás, Catalão (GO).http://repositorio.ufcat.edu.br/tede/handle/tede/11567In view of the importance of teaching instruments in the mediation of learning, research was done on the use of the Service Platform in the teaching and learning process of mathematics with students with intellectual disabilities, in order to verify the benefits pointed out by the teachers who implemented this new how to use the projector. Therefore, it was necessary to compare the exercises performed on the Service Platform with the exercises that students do in a conventional way on a white board at school and investigate how the Platform instigates the learning of these students. A case study research was conducted in 2019, in two days with alternation of classes on the Service Platform and in a traditional way, with the execution of exercises, on both days of research, whose material produced was used for data analysis. Interviews were also conducted with the teachers who created the platform. Therefore, it was found that there was an increase in the percentage of correct answers in the Service Platform, managing to improve the correct response rates in conventional activities used in the school. In addition, it was observed that this assisted technology was the object of transition from real content to its abstraction, by students with intellectual disabilities. Thus, with a qualitative and quantitative analysis, it was found the learning of mathematics with the use of this learning device, concluding that the Service Platform contemplates the learning of students with intellectual disabilities.Attribution-NonCommercial-NoDerivatives 4.0 InternationalPlataforma de atendimentoDeficiente intelectualEnsino de matemáticaTecnologia assistivaService plataformIntellectual disabledMathematics teachingAssistive technologyCIENCIAS EXATAS E DA TERRA::MATEMATICA::MATEMATICA APLICADADissertação
