Mobilização de saberes e conhecimentos matemáticos por meio do software Geogebra no ensino fundamental

Abstract

Technological advances have brought about significant changes in our society, changing the way we interact and learn, as well as enabling instant access to various information. In education, it is no different, as every day a multitude of technologies emerge covering practically all areas of knowledge. These technologies offer a range of technological resources that enable the transmission of information through communication and electronic media, in addition to multimedia, telematic networks and robotics. They are acquiring more and more space in pedagogical practice, being an additional aid in the teaching and learning process. In this sense, the objective was to analyze the mobilization of trigonometry knowledge in the right triangle using . It is free dynamic mathematics software, with the aim of being used mainly in teaching and learning Mathematics in primary and secondary schools of basic education. For this, the Didactic Engineering proposed by Michelè Artigue and the Theory of Didactic Situations described by Guy Brousseau were used as theoretical and methodological references. A face-to-face meeting was held in the computer laboratory of the School of Elementary and Secondary Education Study and Work, in Porto Velho – RO. Data production occurred through resolution protocols. The research participants were students in the 9th year of elementary school. With the development of the research, the mobilization of mathematical knowledge was observed through the presentation of proposed problem solving carried out through reading and interpretation, observation of deductions. Therefore, the software presented itself as a significant tool in the process of teaching and learning mathematics, providing alternatives for improving education. Teachers should be encouraged to use this tool, aiming for meaningful learning.
