No. of bitstreams: 1 GeorgianeAS_TESE.pdf: 2906729 bytes, checksum: 517705591ff207d241daa57f0bb21381 (MD5) Previous issue date: 2013-03-15 / The thesis presents a systematic description about the meaning, as Skemp, relational understanding and understanding instrumental, in the context of mathematics learning, being that we had as a guide his understanding of the schema. Especially, we analyze some academic productions, in the area of Mathematics Education, who used the categories of understanding relational and instrumental understanding how evaluative instrument and we see that in most cases the analysis is punctual. Being so, whereas the inherent understanding relational schema has a network of connected ideas and non-insulated, we investigated if the global analysis, where it is the understanding of the diversity of contributory concepts for formation of the concept to be learned, is more appropriate than the punctual, where does the understanding of concepts so isolated. For this, we apply a teaching module, having as main content the Quaternos Pythagoreans using History of Mathematics and the work of Bahier (1916). With the data we obtained the teaching module to use the global analysis and the punctual analysis, using research methodology the Case Study, and consequently we conduct our inferences about the levels of understanding of the subject which has made it possible for us to investigate the ownership of global analysis at the expense of punctual analysis. On the opportunity, we prove the thesis that we espouse in the course of the study and, in addition, we highlight as a contribution of our research evidence of need for a teaching of mathematics that entices the relational understanding and that evaluation should be global, being necessary to consider the notion of schema and therefore know the schematic diagram of the concept that will be evaluated / O presente trabalho apresenta uma descri??o sistem?tica acerca do que significa, segundo Skemp (1980,1989), compreens?o relacional e compreens?o instrumental, no ?mbito da aprendizagem matem?tica, sendo que tivemos como norte ? sua compreens?o sobre esquema. Sobretudo, analisamos alguns trabalhos acad?micos, na ?rea de Educa??o Matem?tica, que fizeram uso das categorias de compreens?o relacional e compreens?o instrumental enquanto instrumento avaliativo e detectamos que na maioria dos casos a an?lise ? pontual. Diante disso, considerando que o esquema inerente ? compreens?o relacional apresenta uma rede de ideias conectadas e n?o isoladas, investigamos se a an?lise global, na qual considera-se a compreens?o da diversidade de conceitos contributivos ? forma??o do conceito a ser aprendido, ? mais apropriada que a pontual, na qual considera a compreens?o de conceitos de modo isolado. Para tanto, aplicamos um m?dulo de ensino, tendo como conte?do principal os quaternos pitag?ricos utilizando a Hist?ria da Matem?tica e a obra de Bahier (1916). Com o referido m?dulo de ensino obtivemos os dados para realizarmos tanto a an?lise global quanto a pontual, utilizando como modalidade de pesquisa o Estudo de Caso, e consequentemente realizamos nossas infer?ncias acerca dos n?veis de compreens?o apresentados pelos sujeitos o que nos possibilitou investigarmos a apropria??o da an?lise global em detrimento da an?lise pontual. Na oportunidade, comprovamos a tese que defendemos no decorrer do estudo e, al?m disso, apontamos como contribui??o da nossa pesquisa a evid?ncia da necessidade de um ensino de Matem?tica que promova a compreens?o relacional e que avalia??o a ser realizada deve ser global, sendo necess?rio levar em considera??o a no??o de esquema e consequentemente conhecer o diagrama esquem?tico do conceito a ser avaliado

No. of bitstreams: 1 MariaCAB.pdf: 633984 bytes, checksum: 9739dba9dc013192725090e07643d0d7 (MD5) Previous issue date: 2008-08-08 / The current research had as main objective to analyze the possibility of knowledge elaboration/re-elaboration about ideas and algorithmic procedures related to basic operations by pupils of the 6th degree fundamental teaching in a significant learning process. This way the study had as basis a methodological intervention developed in a 6th degree class of a Fundamental Teaching Municipal School in the city of Jo?o Pessoa, PB. The research had as central steps the application of pre-tests (1 and 2); the execution of semi-structured interviews with the pupils involved in the theme deep studies; the elaboration and development of teaching activities, having as referential the significant learning and the application of a pre-test. The data collected in the pre-tests (1 and 2) showed a low level of the pupils comprehension about the contents related to the four operations. The answers to the post-test questions were analyzed mainly from the qualitative point of view based on the mathematic concepts comprehension theory proposed by Skemp (1980) having as complementary subsidy data collected through interviews. The analysis of the results obtained in the post-test showed that the major part of pupils reached a relational comprehension about the ideas and algorithmic procedures related to addition, subtraction, multiplication, and division. Such results showed us that the application of a teaching methodology that privileges the content comprehension, considering the pupils previous knowledge and the reflection about the action along the activities proposed, made possible the elaboration or re-elaboration of knowledge by pupils regarding to contents adopted as theme for our research / A presente pesquisa teve como principal objetivo analisar a possibilidade de elabora??o/reelabora??o de conhecimento acerca das id?ias e procedimentos algoritmos relativos ?s opera??es b?sicas, por alunos do 6? ano do Ensino Fundamental, em um processo de aprendizagem significativa. Para tanto, o estudo teve como base uma interven??o metodol?gica desenvolvida em uma turma do 6? ano de uma Escola da Rede Municipal de Ensino Fundamental da cidade de Jo?o Pessoa-PB. A pesquisa teve como etapas centrais a aplica??o de pr?-testes (1 e 2); a realiza??o de entrevistas semi-estruturadas com os alunos envolvidos nos estudos de aprofundamento do tema; a elabora??o e desenvolvimento de atividades de ensino, tendo como referencial a aprendizagem significativa, e a aplica??o de um p?s-teste. Os dados coletados nos pr?-testes (1 e 2) revelaram um baixo n?vel de compreens?o dos alunos acerca dos conte?dos relativos ?s quatro opera??es. As respostas ?s quest?es do p?s-teste foram analisadas principalmente do ponto de vista qualitativo, com base na teoria de compreens?o de conceitos matem?ticos, proposta por Skemp (1980), tendo como subs?dio, complementar dados coletados por meio de entrevistas. A an?lise dos resultados obtidos no p?s-teste revelou que a maior parte dos alunos atingiu uma compreens?o relacional acerca das id?ias e procedimentos algor?tmicos relativos ? adi??o, subtra??o, multiplica??o e divis?o. Tais resultados indicam que ? aplica??o de uma metodologia de ensino que privilegie a compreens?o dos conte?dos, considerando o conhecimento pr?vio dos alunos e a reflex?o sobre a a??o ao longo das atividades propostas, possibilitaram a elabora??o ou reelabora??o de conhecimento por parte dos alunos, pertinentes aos conte?dos adotados como tema para nossa pesquisa
