CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / Este trabalho tem como tema central a aplicaÃÃo de tÃcnicas de ensino de geometria espacial em especial o ensino de poliedros, destacando-se o Teorema de Euler e os poliedros regulares (poliedros de PlatÃo). Analisamos as definiÃÃes, teoremas e suas demonstraÃÃes, destacando-se um pouco da histÃria do matemÃtico Leonhardo Euler, e as curiosidades acerca do seu teorema para poliedros. Discutimos ainda as dificuldades educacionais do ensino de matemÃtica e os elementos que podem estar ligados a essa dificuldade como tambÃm alternativas que podem ser aplicadas na prÃtica de ensino de professores dessa Ãrea. Diante das dificuldades propomos uma metodologia de ensino baseada na combinaÃÃo de duas tÃcnicas: uso de softwares e aprendizagem cooperativa, pois, ambas vem sendo muito discutidas como alternativa viÃvel de ensino. Destacamos inclusive quais as principais vertentes do pensamento do uso de software como ferramenta de ensino ou mÃquina de ensinar, assim como, analisarmos as caracterÃsticas de ensino cooperativo, apresentando as dificuldades encontradas na tentativa de implantaÃÃo desse mÃtodo de ensino, alÃm, de ressaltarmos tambÃm as vantagens alcanÃadas apÃs a superaÃÃo dos obstÃculos iniciais. Analisou-se tambÃm os softwares Poly e Educandus que foram utilizados no projeto de ensino diferenciado, onde destacamos as potencialidades, alÃm das limitaÃÃes que estes apresentavam, sugerindo alternativas para a devida complementaÃÃo do professor que acompanhe os alunos envolvidos no estudo. Sugerimos tambÃm, atividade direcionada para uso do Poly, no intuito de levar o participante a explorar todos os recursos do software ao mÃximo assim para minimizarmos as dificuldades de visualizaÃÃo e representaÃÃo dos poliedros. Por Ãltimo aplicamos avaliaÃÃes qualitativas e quantitativas onde verificamos as potencialidades da metodologia utilizada em comparaÃÃo com o ensino convencional, alÃm de fazermos uma anÃlise dos erros mais comuns cometidos pelos alunos do ensino convencional e os alunos do ensino experimental. / This work is focused on the application os spatial geometry teaching techniques especially the teaching of polyhedrons, being detached the Euler's theorem and regular polyhedrons (Plato's polyhedrons).Initially we analyzed the definitions and theorems and their respective demonstrations, including some history of the fantastic mathematical Leonhardo Euler, and his curiosities about his theorem for polyhedrons. We also discussed the educational difficulties of mathematics teaching and the elements that can be linked to these difficulties as well as alternatives that may be applied to teachers' teaching practice in this area. With so many difficulties, we proposed a teaching methodology based on a combination of two techniques: use of software and cooperative learning, for both methods have been much discussed as a viable alternative to education. We also detached the main thought strands of the use of software as a teaching tool or teaching machine, as well as we analyzed the cooperative teaching characteristics, showing the difficulties encountered when we tried to implement this teaching method, in addition, we also put in relief the advantages achieved after overcoming the initial obstacles. It was also analyzed the softwares Poly and Educandus that have been used in the different educational project, where we detached their potential beyond their limitations, suggesting alternatives for due complementation of the teacher who accompanied the students involved in the study. We also suggested, activities directed for the use of Poly in order to lead the participant to explore the software's potential to its maximum in order to minimize the visualization difficulties and representation of polyhedrons. Finally, we applied qualitative and quantitative assessments where we verified the potential of the used methodology compared to formal education, and we did an analysis of the most common mistakes
