Besides the aspect related to resources that can make a methodological approach to teaching and learning, the ease of locating and retrieving information on the Internet allows you to make possible a more contextualized and challenging work. In this sense, we consider the study of concepts related to Spatial Geometry in a perspective that uses the History of Mathematics. The research is supported by theoretical assumptions that the historical context is needed to liven and arouse the interest of the student to relate the content to his daily life. Moreover, it is considered that for effective teaching improvement it is important for a teacher to incorporate technology to the classes. In the search for answers to the research question guiding this work, which sought to see how we could diversify the way Geometry is studied in High School, we developed a teaching method using the History of Mathematics in a blog especially created for this activity. The investigation was conducted with High School students from second grade classes. The content covered, in a sequence of ten activities, is related to the study of the Pyramids, and the background to the historical context could not be timelier: the Pyramids of Egypt. After the development of the activities, all students responded to the survey instrument, where it was possible to record their feelings and opinions about the work done. The work being completed, it was considered that the result was very satisfactory, because there are indicators, from the sensations perceived by the author during the work and later in this analysis, which the proposal methodology allowed the students to have their performance and motivation increased as we supposed to be. / O ensino de Matem?tica, especialmente de Geometria Espacial, ? potencialmente beneficiado pelas tecnologias associadas aos recursos da Web 2.0, principalmente no que tange ?s possibilidades de integra??o de m?dias e intera??o entre os alunos e os objetos de estudos. Al?m do aspecto relacionado aos recursos que podem compor uma abordagem metodol?gica para ensino e aprendizagem, a facilidade de localiza??o e recupera??o de informa??es na Internet permite que se viabilize um trabalho mais contextualizado e desafiador. Nesse sentido, consideramos o estudo dos conceitos relacionados ? Geometria Espacial numa perspectiva que utilize a Hist?ria da Matem?tica. A investiga??o est? amparada pelos pressupostos te?ricos de que a contextualiza??o hist?rica se faz necess?ria para dar vivacidade e despertar o interesse do aluno para relacionar os conte?dos ao seu cotidiano. Al?m disso, considera-se que, para uma efetiva qualifica??o no ensino, seja importante o professor incorporar a tecnologia ?s aulas. Na busca por respostas ? quest?o de pesquisa norteadora deste trabalho que buscava verificar como se poderia diversificar a forma como se estuda Geometria no Ensino M?dio, desenvolveu-se uma metodologia de ensino usando a Hist?ria da Matem?tica em um blog, especialmente criado para esta atividade. A investiga??o foi realizada com alunos de turmas de 2? s?rie do Ensino M?dio. O conte?do abordado, numa sequ?ncia de dez atividades, est? relacionado ao estudo de Pir?mides e o pano de fundo para a contextualiza??o hist?rica n?o poderia ser mais oportuno: as pir?mides do Egito. Ap?s o desenvolvimento das atividades os alunos responderam ao instrumento de pesquisa onde foi poss?vel registrar suas sensa??es e opini?es sobre o trabalho realizado. Finalizado o trabalho, considerou-se que o resultado foi bastante satisfat?rio, pois existem indicadores, oriundos das sensa??es percebidas pelo autor no decorrer do trabalho e posteriormente nessa an?lise, de que a proposta permitiu que os alunos tivessem seu desempenho e motiva??o elevados.
