Uma proposta de atividades para o estudo de progressões geométricas utilizando fractais e o software geogebra

Abstract

This research aims to present an activities proposal to the Geometric Progressions teaching, by the Fractals construction in GeoGebra software. The work proposes teaching through a methodology that connects the Mathematics with practical actions in a workshop held with sixteen 1st grade High school students, at public school, in Nova Erechim city, SC. Does the research guided by the following question: The Geometric Progressions study at High school, from the Classical Fractals construction in GeoGebra, produces any significant learning for the student? In order to promote the technology insertion in Mathematics classes, the activities has developed with the incentive to interaction between Fractals geometric constructions and the Geometric Progressions mathematical concept. Had as objective to teach the Geometric Progression contents, specifically the concepts of: finite and infinite Geometric Progression; Increasing and decreasing Geometric Progression; and Geometric Progression reason for. The conclusions were obtained from the workshop development and the diagnostic questionnaires. This approach intends, from the student’s interaction with the whole teaching process, to give meaning to the Geometric Progressions learning and to verify if the GeoGebra Software contributed to this process.
