The objectives were to analyze, verify and understand how mobile learning presents itself in the process of studying solids of revolution and polyhedra in the interaction with smartphones. The present work had the theoretical as-sumptions of authors who write conceptions about learning with technology, learning of geo-metry, Mixed Reality, Augmented Reality, m-learning and markers inserted in Education. Technology learning highlights arguments about the most dynamic ways technology brings to the educational environment. Geometry is evidenced as one of the contents that present more difficulties for students of High School, but at the same time benefited by the advances of com-puterized technologies. The Mixed Reality is conceived as a resource that contributes to the interaction with digital information in a real environment and the Augmented Reality, conside-red as a Mixed Reality, promotes a new experience with three-dimensional objects in the lear-ning of spatial geometry. The m-learning is described, through the ideas of the authors that deal with the subject, as a modality of mobile learning that allows the students to be the authors of the own knowledge. Another theoretical conception inserted in the research is the use of Aug-mented Reality markers as an alternative to potentialize the learning process. The research has a qualitative character based on the Discursive Textual Analysis method. During the research, the instruments of data collection used were direct observations, field diaries and questionnai-res. The investigation occurred in a private school in the city of Porto Alegre through an activity with the use of an Augmented Reality application. For data analysis, text mining techniques with a web application using the python programming language were used in order to organize and systematize the descriptive data to facilitate the procedures that make up the Discursive Textual Analysis. Given the results and from the emerging categories of research, it can be affirmed that mobile learning presents itself as an interactive contribution to learning and as an aid in the construction of mathematical knowledge. As final considerations, the research highlights that the learning of spatial geometry with an Augmented Reality application promo-ted the students' engagement, enriched the development of new forms of learning and contribted to a more autonomous study evidencing the student as the central object of learning / Esta disserta??o aborda uma investiga??o sobre a aprendizagem de geometria espacial por meio de dispositivos m?veis com a utiliza??o de um aplicativo de Realidade Aumentada. Os objeti-vos foram de analisar, verificar e entender como o mobile learning se apresenta no processo de estudo de s?lidos de revolu??o e poliedros na intera??o com smartphones. O presente trabalho teve pressupostos te?ricos de autores que escrevem concep??es sobre a aprendizagem com tec-nologia, aprendizagem de geometria, Realidade Mista, Realidade Aumentada, m-learning e marcadores inseridos na Educa??o. O aprendizado com a tecnologia destaca argumenta??es sobre os modos mais din?micos que os recursos tecnol?gicos levam para o ambiente educacio-nal. A geometria ? evidenciada como um dos conte?dos que apresentam mais dificuldades para os estudantes de Ensino M?dio, mas ao mesmo tempo beneficiada pelos avan?os das tecnolo-gias informatizadas. A Realidade Mista ? concebida como um recurso que contribui para a in-tera??o com informa??es digitais em um meio real e a Realidade Aumentada, considerada como uma Realidade Mista, promove uma nova experi?ncia com objetos tridimensionais na aprendi-zagem de geometria espacial. O m-learning ? descrito, por meio das ideias dos autores que tratam do assunto, como uma modalidade de aprendizagem m?vel que permite os estudantes serem os autores do pr?prio conhecimento. Outra concep??o te?rica inserida na pesquisa ? a utiliza??o de marcadores de Realidade Aumentada como uma alternativa de potencializar o processo de aprendizagem. A pesquisa possui car?ter qualitativo embasada no m?todo da An?-lise Textual Discursiva. Durante a pesquisa, os instrumentos de coleta de dados utilizados foram as observa??es diretas, di?rio de campo e question?rios. A investiga??o ocorreu em uma escola particular do munic?pio de Porto Alegre por meio de uma atividade com a utiliza??o de um aplicativo de Realidade Aumentada. Para a an?lise dos dados, foram utilizadas t?cnicas de mi-nera??o de texto com uma aplica??o web mediante a linguagem de programa??o python no intuito de organizar e sistematizar os dados descritivos para facilitar os procedimentos que com-p?em a An?lise Textual Discursiva. Diante os resultados e a partir das categorias emergentes da pesquisa, pode ser afirmado que o mobile learning se apresenta como uma contribui??o in-terativa para a aprendizagem e como aux?lio na constru??o do conhecimento matem?tico. Como considera??es finais, a pesquisa destaca que a aprendizagem de geometria espacial com um aplicativo de Realidade Aumentada promoveu o engajamento dos estudantes, enriqueceu o de-senvolvimento de novas formas de aprendizagem e contribuiu para um estudo mais aut?nomo evidenciando o estudante como o objeto central da aprendizagem

No. of bitstreams: 1 Daina_Maturano_Dias_Martil_Dis.pdf: 2509038 bytes, checksum: d1087d1c8072040402a4173ef97274d0 (MD5) Previous issue date: 2018-08-31 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / This study evaluates the factors involved in granting or denying home detention to women in pretrial detention at the Madre Pelletier Female State Prison (MPFSP), in Southern Brazil. The sampled responds to the requirements established in article 318 of the Brazilian Code of Criminal Procedure (BCCP), which recommends replacing pretrial detention with house arrest to the women who are pregnant or mothers of children under 12 years old. This research was based on two premises: (i) the enactment of Law 13.257/ 2016 known as the Legal Framework for Early Childhood - which promoted the change in the BCCP in order to meet the infants best interests - and (ii) the preparation of technical reports by MPFSP social and psychologist Assistants, later sent to the criminal process district, requesting an analysis to the house arrest granting. It was a mixed design study. Qualitative data were examined by the Discursive Textual Analysis theory, which is composed of three essential elements: unitarization, categorization and communication. Quantitative analysis encompass statistical calculations performed by Statical Package for the Social Scienses, version 21.0 for Windows. Furthermore, the sociodemographic profile of a total of 84 women was raised in the reports on the Justice Court website. From the analysis of the data, it was verified that 32% of the women had their request rejected. By refusing the house arrest the magistracy alleges the maintenance of public order to justify the non-granting for women in detention. However, the sample preponderance shows that the criminal imputation does not accompany violence acts. Homicide crimes accounted for only 7.1%, which shows that the majority of surveyed women in MPFSP could receive the house arrest grant. The interpretation of the discourses content reveals moralistic considerations referring to an idealized motherhood in the mold of the patriarchal culture, considering that these women are unfit for mothering precisely because they are accused of committing a crime. On the other hand, in the cases when house arrest was granting, it was evidenced by the judiciary the understanding of the indispensability of the maternal figure for the care of the children, thus protecting the best interest of the infant. Such findings may contribute to the elaboration of affirmative actions that subsidize the strengthening of house arrest concessions. Under the bastion of the Public Security Policy known as "Zero Tolerance", preventive detention could be understand as a social control tool of women who disregard the social role attributed to the feminine by the androcentric and patriarchal culture here represented by southern criminal justice system. / O presente estudo tem como objetivo conhecer, a partir da utiliza??o da An?lise Textual Discursiva, o tom do discurso da magistratura ga?cha, para conceder ou indeferir a pris?o domiciliar ?s mulheres em situa??o de pris?o preventiva no Pres?dio Estadual Feminino Madre Pelletier, que respondem ao requisito de serem m?es de crian?as menores de 12 anos ou estejam gestantes, conforme preconiza o artigo 318 do C?digo de Processo Penal. A justificativa para elabora??o de tal investiga??o partiu da promulga??o da Lei 13.257/2016, conhecida como Marco Legal da Primeira Inf?ncia ? que promoveu a altera??o no CPP no fito de atender o melhor interesse dos infantes ?, e da elabora??o de relat?rios t?cnicos por Assistentes Sociais e Psic?logas do PEFMP, posteriormente encaminhados para a comarca de origem do processo criminal, solicitando an?lise para a concess?o da pris?o domiciliar. Foi tamb?m levantado o perfil sociodemogr?fico das r?s, totalizando 84 amostras que continham manifesta??o nos despachos no s?tio eletr?nico do TJRS. Tratou-se de estudo com delineamento misto. A an?lise quantitativa foi realizada por meio de c?lculos estat?sticos do Statistical Package for the Social Scienses ? SPSS, vers?o 21.0 para Windows. J? os dados qualitativos foram analisados pela teoria da An?lise Textual Discursiva, e comp?em um ciclo de an?lise composto por tr?s elementos essenciais: a unitariza??o, categoriza??o e comunica??o, que resultaram no corpus das an?lises. A interpreta??o do conte?do dos discursos destacou que, ao indeferir a pris?o domiciliar, a magistratura ga?cha utiliza-se da manuten??o da ordem p?blica para justificar a n?o concess?o da medida cautelar diversa da pris?o para mulheres em situa??o de pris?o preventiva, apresentado algumas considera??es de cunho moralista referentes a uma maternidade idealizada nos moldes da cultura patriarcal, ao considerarem essas mulheres inaptas ? maternagem justamente por serem acusadas de cometimento de delito, em que pese que a preponder?ncia da amostra tenha demonstrado que a imputa??o penal n?o acompanha atos de viol?ncia. Na outra esteira, ao concederem a pris?o domiciliar, ficou evidenciado pela magistratura o entendimento da imprescindibilidade da figura materna para o cuidado dos filhos, resguardando assim o melhor interesse da crian?a. Tal constata??o pode vir a contribuir na elabora??o de a??es afirmativas que subsidiem o fortalecimento das concess?es de pris?o domiciliar, diante do fato, como ficou demonstrado, que a pris?o preventiva de mulheres configura-se enquanto ferramenta de controle social sob a ?gide do recrudescimento da Pol?tica de Seguran?a P?blica conhecida como ?Toler?ncia Zero?.
