Previous issue date: 2011-10-20 / The present dissertation performs a study about abacus part on the continuous education of Elementary School s Mathematic teachers on what concerns the basic operations of addition and subtraction with (re)unification by using the manipulative and/or informatical abacus. Therefore, the research intends to answer the following question: How does a teacher reframe the pedagogical practice while teaching the Decimal Numeral System and the conventional operations of addition and subtraction with (re)unification through manipulative and informatical abacus? In order to do so, we rely ourselves on the Guy Brousseau s Theory of Didactic Situations (TDS) from 1996 that affirms the necessity to trace a way in accordance with the teaching situations that lead the student s learning; and on the work of Pierre L?vy (1993), in which the poles of communication oral, written and virtual create three ways of communication through which the learning process happens. The methodology of this paper was based on the Strategic Research-Action of Franco (2005). The didactic sequence was elaborated in accordance with TDS and used the manipulative and informatical abacus as didactic resource. With the application of the didactic sequence, it was verified that the continued formation of Elementary School s teachers concerning the operations of addition and subtraction on the initial years/levels is pertinent once it has been observed some difficulties of the teachers concerning this mathematical subject. Besides, the analysis of the didactic sequence has allowed one to realize that teachers had some difficulties concerning the numeric representation with order zero, the resolution of operations of addition and subtraction using the manipulative and informatical abacus and the realization of (re)unification on the subtraction with meaning. These observations has been discussed with the teachers and, after that, it has been done some didactic-methodological routings of the operations of addition and subtraction with re(unification) that contributes with the teaching and learning process. / A presente disserta??o realiza um estudo sobre o papel do ?baco na forma??o continuada dos professores de Matem?tica do Ensino Fundamental, acerca das opera??es de adi??o e subtra??o com (re) agrupamento por meio do uso do ?baco manipulativo e/ou inform?tico. Assim, a pesquisa pretende responder a seguinte quest?o: Como o professor ressignifica a sua pr?tica pedag?gica ao ensinar o Sistema de Numera??o Decimal e as opera??es convencionais de adi??o e subtra??o com (re) agrupamento por meio do ?baco manipulativo e inform?tico? Para isso, baseamo-nos na Teoria das Situa??es Did?ticas (TSD) de Guy Brousseau (1996) que afirma ser necess?rio tra?ar um caminho de acordo com as situa??es de ensino que conduza a aprendizagem dos estudantes e, no trabalho de Pierre L?vy (1993), no qual os polos da comunica??o: oral, escrito e virtual, possibilitam as tr?s maneiras de comunica??o pelas quais ocorre a aprendizagem. A metodologia do trabalho apoiou-se na Pesquisa-a??o Estrat?gica de Franco (2005). A sequ?ncia did?tica foi elaborada de acordo com a TSD e, o ?baco manipulativo e inform?tico foi usado como ferramenta did?tica. Com a aplica??o da sequ?ncia did?tica foi verificado que a forma??o continuada de professores do Ensino Fundamental, nas s?ries/anos iniciais a respeito das opera??es de adi??o e subtra??o com (re) agrupamento ? pertinente, visto que foram observadas algumas dificuldades dos professores sobre esse conte?do matem?tico. Al?m disso, a an?lise da sequ?ncia did?tica permitiu perceber que as professoras tinham dificuldade: na representa??o num?rica com a ordem zero, na resolu??o das opera??es de adi??o e subtra??o utilizando o ?baco manipulativo e/ou inform?tico e na realiza??o do (re) agrupamento na subtra??o com significado. Tais observa??es foram discutidas com as professoras, ap?s a discuss?o, foram realizados encaminhamentos did?tico-metodol?gicos das opera??es de adi??o e subtra??o com (re) agrupamento que contribuem com o processo de ensino e aprendizagem.
