Manifestação geométrica das formas indeterminadas de funções: situações didáticas apoiadas na tecnologia

Abstract

This work had as main objective to present an educational proposal for indeterminate and rule of L'Hospital ways through teaching sequences structured, based on assumptions of Fedathi sequence as teaching methodology, and the exploitation of Geogebra software as a tool for education. Another objective of the research is to propose to the teachers support material by means of video classes that can assist them in classes on the subject. As for the research methodology employed, we chose the Didactic Engineering considering that it is a reference, as one of its features is to unite the theoretical research and practical action through teaching sessions. We emphasize that we used only the first two stages of the Didactic Engineering, in line with the objectives pursued in our research. According to CAPES the Professional Masters highlights the technical / production technology in teaching as educational products that can be consumed by teachers and other professionals involved with teaching. In this perspective, we produced video classes designed from teaching sequences and became willing a blog structured materials on the subject. Thus, we believe that the calculation of teaching, more specifically the teaching of Indeterminate forms and L'Hôpital rule, submit improvements when combined with a methodology that enables the student to build their own knowledge, as in the case of Fedathi sequence. In this sense, the inclusion of technology through the Geogebra software, enables the student to an alternative way and, in our view, appropriate to the construction of new knowledge.
