The I.T. labs set up in public schools, which are high cost investments, often get forgotten and become obsolete. Nowadays, with technology evolution and the appearance of smartphones and tablets, new educational apps are being developed for these tools. Many discussions have been held regarding the real applicability of such tools, if they can really help or simply distract the student, but it is a known fact that they are present all the time and that it is worthy to use them in order to improve the learning experience. Sketchometry is a dynamic geometry app with basic commands that could help students with geometry and mathematical functions. The moving of constructions, usually made by gestures and with the imagination of teachers, can now be done with the touch of fingers on the screens of mobile phones and tablets, making visualization easier. Teachers, however, still have difficulties implementing such tools in their classes. This essay attempted to evaluate the opinion of students of primary school, undergraduates, masters degree students and masters on the usage of smartphones/tablets in class. Activities with Sketchometry were shown, followed by an evaluation questionnaire for the research. The results obtained indicate that some of the reasons provided not to use the tools, are the number of students per classroom, the lack of structure in schools and the lack of skill of teachers. When it comes to licentiates, master's degree students and graduates from UFRRJ's PROFMAT, the majority of teachers and soon to be teachers believe in the usage of the tools, that the students are interested in using them and that there are indeed obstacles but they are not insuperable. O ensino da Matem?tica muda lentamente, enquanto o perfil dos alunos muda a cada gera??o. Os laborat?rios de inform?tica montados nas escolas p?blicas, investimento de alto custo, muitas vezes ficam abandonados e se tornam obsoletos. Atualmente, com a evolu??o da inform?tica e o surgimento de celulares e tablets com tecnologia touchscreen, novos aplicativos educativos t?m sido desenvolvidos para essas ferramentas. Muito se tem discutido acerca da real aplicabilidade desses equipamentos, se podem realmente auxiliar na aprendizagem ou se apenas distraem o aluno, mas o certo ? que eles est?o presentes a todo momento e que vale a pena se valer disso para buscar melhorar o aprendizado. O Sketchometry ? um aplicativo de geometria din?mica, com comandos simples, que pode ajudar o estudante no estudo da geometria e de fun??es Matem?ticas. A movimenta??o das constru??es, antes feita com gestos e imagina??o por tantos professores, hoje pode ser realizada com o toque dos dedos nas telas de celulares e tablets, facilitando a visualiza??o. Os professores, no entanto, ainda t?m dificuldades em implementar esse tipo de ferramenta em suas aulas. Este estudo buscou avaliar a opini?o de estudantes do ensino fundamental, graduandos, mestrandos e mestres acerca da utiliza??o de celulares/tablets em sala de aula. Atividades com o Sketchometry foram realizadas e, em seguida, um question?rio de avalia??o para a pesquisa foi aplicado. Nos resultados obtidos, observou-se que entre os motivos citados para a n?o utiliza??o dessas ferramentas, est?o o n?mero de alunos por sala, a falta de estrutura nas escolas, o despreparo do pr?prio professor, entre outros. Com rela??o aos licenciandos, mestrandos e egressos do PROFMAT da UFRRJ, a maioria dos professores e futuros professores acredita na utiliza??o desse tipo de ferramenta, e que existe interesse dos alunos para que sejam utilizadas, que os obst?culos existem mas n?o s?o intranspon?veis.
