Resumo
A presente pesquisa, vinculada à linha “Processos Formativos, Ensino e Aprendizagem”, foi implusionada pela questão: Qual a relação entre a álgebra acadêmica e a álgebra escolar expressa nas concepções dos licenciandos e professores do curso de licenciatura em matemática? E, teve como objetivo geral investigar a relação entre a álgebra acadêmica e a álgebra escolar expressa nas concepções de álgebra e do seu ensino entre professores e licenciandos matriculados no curso de licenciatura em matemática da FCT – Unesp de Presidente Prudente, tendo em vista subsidiar reflexões sobre a formação inicial de professores de matemática. O referencial teórico constitui-se das teorias da educação matemática acerca da álgebra, da relação entre álgebra acadêmica e álgebra escolar, das concepções de álgebra e do seu ensino e da formação inicial de professores de matemática. Com abordagem qualitativa e delineamento descritivo analítico, a pesquisa teve como procedimentos metodológicos: análise documental, questionário e entrevista, realizados ao longo do curso. O material de análise incluiu o Projeto Pedagógico do referido curso, os questionários aplicados aos licenciandos no 1º e 3º ano, as entrevistas realizadas com os licenciandos no 2º e 4º ano do curso bem como as entrevistas realizadas com professores que ministraram disciplinas diretamente relacionadas à álgebra. A análise documental associada às entrevistas realizadas com professores e licenciandos indicou que o curso atende às orientações legais vigentes. No entanto, não há justificativa para a escolha de disciplinas da grade curricular, tendo em vista a sua relevância para a formação do futuro professor. Nas proposituras do plano de ensino das disciplinas Álgebra Elementar e Álgebra I observou-se nuances da relação entre a álgebra acadêmica e a álgebra escolar, mas o seu desenvolvimento mostrou-se incoerente com tais proposituras. Na prática, priorizava-se o ensino do conhecimento matemático, caracterizando-se no modelo da racionalidade técnica, reforçando procedimentos vivenciados e internalizados durante o processo de escolarização anterior à licenciatura. No curso analisado, a ênfase curricular, quando se trata de álgebra, recaiu sobre a álgebra das estruturas. Relacionando os modelos relativos ao ensino de álgebra destacados pelos licenciandos em diversos momentos ao longo do curso, foi possível perceber que se trata de modelos pautados na definição, seguida de exemplos, resolução de exercícios, que no geral, se aproximam expressivamente da álgebra acadêmica. Quando os licenciandos definem álgebra, salienta-se à concepção estrutural. Por outro lado, ao se referirem à aplicabilidade da álgebra, destaca-se a concepção ferramenta. Considerando que a concepção ferramenta se sobressaiu entre as demais, conclui-se que as concepções dos licenciandos encontram-se em consonância com a álgebra escolar, com algumas marcas da álgebra acadêmica, representada pela concepção estrutural. As concepções de álgebra dos professores se aproximaram à concepção estrutural. Explicitam que, para ser um bom professor de matemática basta ter domínio sólido de conteúdo e saber ensinar; desse modo apontaram a supervalorização das disciplinas específicas em detrimento das disciplinas pedagógicas, enfatizando a álgebra acadêmica. O presente estudo concluiu que a relação entre a álgebra acadêmica e álgebra escolar na formação inicial do licenciando não é significativa a ponto de ressignificar os conhecimentos sobre ensino de álgebra do futuro professor.
This research, linked to the line "Formative Processes, Teaching and Learning," was driven by the question: What is the relationship between academic algebra and school algebra expressed in the conceptions of undergraduate and professors of mathematics degree course? And has had as general goal to investigate the relationship between academic algebra and school algebra expressed in algebra concepts and their teaching between professors and undergraduates enrolled in the Mathematics degree of FCT - UNESP of Presidente Prudente, in order to subsidize reflections on initial training of mathematics teachers. The theoretical framework was constituted of mathematics educational theories about algebra, the relationship between academic algebra and school algebra, the algebra concepts and their education and initial training of mathematics teachers. Using qualitative approach and descriptive analytic design, the research has had as methodological procedures: document analysis, questionnaire and interview, conducted throughout the course. The analysis material included the pedagogical project of that course, the questionnaires given to undergraduates in the 1st and 3rd year, interviews with undergraduates on the 2nd and 4th year of the course as well as interviews with teachers who taught subjects directly related to algebra. The documentary analysis associated with interviews carried out with professors and undergraduates indicated that the course meets the statutory guidelines. However, there is no justification for the choice of the curriculum subjects, in view of its relevance to the formation of the future teacher. In the propositions of the teaching plan of the subjects elementary algebra and Algebra I, it was observed nuances of the relationship between academic algebra and school algebra, but its development was found to be inconsistent with such propositions. In practice, the mathematical knowledge education was prioritized, and characterizing itself in the model of technical rationality, reinforcing procedures experienced and internalized during the process prior to the school degree. Over this course, the curricular emphasis when it comes to algebra, has fell on the structures algebra. Relating the models to the teaching of algebra highlighted by undergraduates at several points along the course, it was revealed that it is guided by models in the definition, followed by examples, exercises solving, which overall approach expressively of academic algebra. When the undergraduates define algebra, structural design is stressed. On the other hand, when referring to the algebra applicability, the design tool is highlighted. Considering that the tool design stood out among the others, it is concluded that the conceptions of undergraduates are in line with the school algebra, with some marks of academic algebra, represented by the structural design. The algebra concepts of the teachers have approached to the structural design. They explain that to be a good mathematics teacher it‟s just necessary to have solid domain content and know how to teach; thereby they pointed to the overvaluation of specific subjects at the expense of educational disciplines, emphasizing academic algebra. This study has concluded that the relationship between academic algebra and school algebra in the initial formation of the undergraduate is not significant enough to reframe the future teacher‟s knowledge related to the algebra teaching.
