FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico === This research examined the teaching of concept of base of a vector space according to the premises mediated by Fedathi Sequence during the discipline âIntroduction to Algebraâ in the course of Engineering of Teleinformatic at Federal University of CearÃ. The objective was to determine whether the use of Fedathi Sequence specifically in classes about the concept of base provides resources capable of becoming Meta Lever, allowing students an education based on the reflection on the worked contents. In this sense, the investigation was conducted in the form of case study, having as subject the teacher of discipline, which allowed the observation during his classes and planning, as well as having granted an interview. The results indicated that the Fedathi Sequence favored the use of resources that could become Meta Lever for students, being decisive in mediating the teacher, once the teacher behavior to use it in the classroom motivates students to reflection. We consider theories ML and FS, in this research, are complementary, and therefore we indicate that the teacher know such tools and their potential for use in teaching of concept of base, awakening the teacher an awareness of the role of mediation suggested by Fedathi Sequence. === Esta pesquisa analisou o ensino da noÃÃo de base de um espaÃo vetorial mediado segundo os pressupostos da SequÃncia Fedathi durante a disciplina de IntroduÃÃo à Ãlgebra do curso de Engenharia de TeleinformÃtica da Universidade Federal do CearÃ. Objetivou-se verificar se o uso da SequÃncia Fedathi, especificamente, nas aulas sobre o conceito de base, proporciona recursos passÃveis de se tornarem Alavanca Meta, permitindo aos alunos um ensino baseado na reflexÃo sobre os conteÃdos trabalhados. Nesse sentido, a investigaÃÃo foi conduzida na forma de estudo de caso, tendo como sujeito o professor da disciplina, que permitiu a observaÃÃo durante suas aulas e planejamentos, alÃm de ter concedido uma entrevista. Os resultados encontrados apontaram que a SequÃncia Fedathi favoreceu o uso de recursos passÃveis de se tornarem Alavancas Meta para os alunos, sendo determinante na mediaÃÃo do professor, de modo que a postura docente ao utilizÃ-la em sala de aula motivava os alunos à reflexÃo. Consideramos que as teorias AM e SF, nessa pesquisa, se complementaram, e, portanto, indicamos que o professor conheÃa tais ferramentas e seu potencial de uso no ensino de base, despertando no professor uma consciÃncia do papel da mediaÃÃo preconizada pela SequÃncia Fedathi.
