Uma aplicação da Sequência Fedathi no ensino de progressões geométricas e a formação do professor no IFCE

Abstract

This article provides a theoretical discussion about teaching and methodological elements related to the concept of geometric progressions. This content of study, compulsory in school education, is an important element of specific knowledge for future Mathematics teachers. Some of the methodological aspects discussed include the issues of quality of textbooks and the use of technology in the intuitive teaching of the referred concept. Some considerations related to the application of the learning methodology called Fedathi’s Sequence are also presented. Its use exemplifies certain moments of the teaching/learning process which promote student's intuition and try to answer particular questions which are recurrent in the training environment of Mathematics teachers, such as: How do you teach geometric progressions? Which methodology should be employed? These questions seem natural for a future teacher. However, theses and dissertations are also discussed, some of them produced in other countries, which indicate problems in the academic studies and do not prepare the teachers-to-be to answer these and other specific questions. Finally, there are the final considerations and recommendations for the future teacher who graduates from the Federal Institute of Education, Science and Technology of Ceará - IFCE.
