Previous issue date: 2015-03-16 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / The aim of this work is to analyze how math teachers participate in the development of mathematical tasks that constitute an educational curriculum material in a collaborative work and to analyze mathematical tasks produced by these teachers in this context. Thus, the focus of this research is the participation of teachers and the production of mathematical tasks. Thereby, theoretical constructs presented by Jean Lave and Etienne Wenger were used to understand the participation of teachers and tasks markers presented by Jonei Barbosa used as reference for the analysis of mathematical tasks. The context of this research were the meetings of the Mathematics Educational Watch (OEM-Bahia) based at the Federal University of Bahia (UFBA) and formed by teachers (basic and college education) and students with Degree in Mathematics and Post-Graduate at the State University of Feira Santana and Federal University of Bahia. The methodological approach was qualitative, in which we used as procedures of data collection observation and interviews stimulated for analyzes relating to the participation of teachers, and document analysis of mathematical tasks that constitute an educational curriculum materials developed by teachers during the collaborative work. The results showed that the participation of teachers in the development of mathematical tasks occurs in three distinct ways: contemplating common goals of the group, sharing ways to develop investigative or exploratory mathematical questions and producing tasks in view of the practices involving other math teachers. Ways to participate relate to the joint undertaking established by the group for the preparation of tasks, with the list shared repertoire group members, which allowed evidence of changes in practices in which teachers participate and with what the group reifies from participation in social practice. In terms of the tasks that were developed through the participation of teachers in the OEM-Bahia we can see that the mathematical tasks performed in convergent, divergent and alternate forms, depending on the task markers, allowing an analysis of the freedom of choice of group during the design of tasks, depending on the practice that teachers involved and the context of the classroom. In terms of mathematical tasks markers, the analysis allowed us to expand the theoretical construct, indicating the possibility of tasks with alternative insulation because the relationships established during the implementation of tasks can be in charge of teachers and negotiations with the students. In addition, we propose the marker in relation to the procedures that are required from students during the implementation of mathematical tasks, called teaching focus. This analysis allowed us to realize that both tasks markers as the framework for analyzing mathematical tasks theoretically allow further analysis of mathematical tasks designed in different contexts and social practices. / O objetivo desta disserta??o ? analisar como professores de matem?tica participam da elabora??o de tarefas matem?ticas que constituem um material curricular educativo em um trabalho colaborativo e analisar as tarefas matem?ticas produzidas por esses professores nesse contexto. Assim, o foco desta investiga??o ? a participa??o dos professores e a produ??o das tarefas matem?ticas. Desta forma, os constructos te?ricos apresentados por Jean Lave e Etienne Wenger foram utilizados para compreender a participa??o dos professores e os marcadores de tarefas apresentados por Jonei Barbosa utilizados como refer?ncia para a an?lise das tarefas matem?ticas. O contexto desta pesquisa foram as reuni?es do Observat?rio da Educa??o Matem?tica (OEM-Bahia) sediado na Universidade Federal da Bahia (UFBA) formados por professores (educa??o b?sica e superior) e estudantes da Licenciatura em Matem?tica e P?s-Gradua??o da Universidade Estadual de Feira de Santana e da UFBA. A abordagem metodol?gica utilizada foi a qualitativa, na qual utilizamos como procedimentos de coleta de dados a observa??o e as entrevistas estimuladas para as an?lises referentes ? participa??o dos professores, e an?lise documental das tarefas matem?ticas que constituem um material curricular educativo elaboradas pelos professores durante o trabalho colaborativo. Os resultados apontaram que a participa??o dos professores na elabora??o de tarefas matem?ticas ocorre de tr?s formas distintas: contemplando objetivos comuns do grupo, compartilhando sobre modos de elaborar quest?es matem?ticas investigativas ou explorat?rias e produzindo tarefas na perspectiva das pr?ticas que participam outros professores de matem?tica. Essas formas de participar t?m rela??o com o empreendimento conjunto estabelecido pelo grupo para a elabora??o das tarefas, com o repert?rio compartilhado entre os membros do grupo que possibilitou ind?cios de mudan?as nas pr?ticas que os professores participam e com o que o grupo reifica a partir da participa??o na pr?tica social. Em termos das tarefas que foram elaboradas por meio da participa??o dos professores no OEM-Bahia podemos observar que as tarefas matem?ticas se apresentaram nas formas convergentes, divergentes e alternadas, a depender dos marcadores de tarefas, permitindo uma an?lise sobre a liberdade de escolha do grupo durante o delineamento das tarefas, a depender da pr?tica que os professores participam e do contexto das salas de aula. Em termos dos marcadores de tarefas matem?ticas, a an?lise nos permitiu expandir o constructo te?rico, apontando a possibilidade de tarefas com isolamento alternativo, pois as rela??es estabelecidas durante a implementa??o de tarefas podem ficar por conta dos professores e das negocia??es com os estudantes. Al?m disso, propomos o marcador com rela??o aos procedimentos que s?o requeridos aos estudantes durante a implementa??o de tarefas matem?ticas, a este denominamos foco de ensino. Essa an?lise possibilitou compreendermos que tanto os marcadores de tarefas quanto o quadro de an?lise de tarefas matem?ticas permitem aprofundar teoricamente a an?lise de tarefas matem?ticas elaboradas em diferentes contextos e pr?ticas sociais.
