ResoluÃÃo de problemas de congruÃncia de triÃngulos com auxÃlio do software Geogebra / Solving triangles congruence problems using Geogebra software

Francisco Ricardo Nogueira de Vasconcelos 20 August 2015 (has links)
nÃo hà / O nosso desafio como professor à possibilitar a melhoria da qualidade do ensino em MatemÃtica buscando meios de garantir a formaÃÃo de cidadÃos capazes de reconhecer o seu papel perante a sociedade e descobrir caminhos elucidativos para o desempenho de uma carreira profissional promissora. Nesse sentido buscamos focar a nossa pesquisa em aÃÃes pedagÃgicas que possibilitem o desenvolvimento das potencialidades cognitivas dos alunos no estudo de congruÃncia. Para isso, propomos o uso do software GeoGebra como ferramenta didÃtica para as aulas de Geometria Plana, por entendermos que esse recurso favorece ao aluno um ambiente favorÃvel ao desenvolvimento da aprendizagem e coloca o professor com mediador no processo de sistematizaÃÃo conceitual das ideias matemÃticas necessÃrias para o desenvolvimento das estruturas cognitivas dos alunos. O objetivo do nosso estudo consiste em subsidiar os alunos do curso de licenciatura em MatemÃtica do Instituto Federal de EducaÃÃo, CiÃncia e Tecnologia, no sentido de utilizar o software GeoGebra como ferramenta didÃtica auxiliar para a resoluÃÃo de problemas de Geometria Plana, que envolvem casos de congruÃncia de triÃngulos. Para a anÃlise e coleta de dados foi realizado o estudo do projeto pedagÃgico do curso e a realizaÃÃo de 01 minicurso para utilizaÃÃo do software GeoGebra destinado a 21 alunos regularmente matriculados na disciplina de Geometria Plana. Utilizamos como instrumentos de pesquisa: 02 questionÃrios diagnÃsticos, observaÃÃo e o registro fotogrÃfico. As anÃlises dos resultados evidenciaram que os alunos se mostraram interessados ao uso do software GeoGebra em sala de aula. O minicurso e as atividades didÃticas aplicadas tiveram um bom nÃvel de aceitaÃÃo por parte dos futuros professores de MatemÃtica. As conclusÃes ressaltam que o uso do software GeoGebra deve ser entendido como ferramenta didÃtica alternativa para o ensino de Geometria, no sentido de proporcionar ao aluno, uma metodologia dinÃmica, interativa e lÃdica para se aprender MatemÃtica. / Our challenge as a teacher is to enable the improvement of education quality in mathematics looking for ways to ensure the formation of citizens able to recognize their role in society and find illuminating paths to the performance of a promising career. In this sense, we seek to focus our research on pedagogical actions which enable the development of the students cognitive potential. For this, we propose the use of GeoGebra software as a teaching tool for Plane Geometry classes, because we believe that this resource provides a favorable environment for the development of learning to the student and places the teacher as a mediator in the process of conceptual systematization of the necessary mathematical ideas to the development of the students cognitive structures. The aim of our study is to support the students of degree in Mathematics from the Federal Institute of Education, Science and Technology in order to use GeoGebra software as a teaching tool to help solving plane geometry problems involving cases of congruence triangles. For analysis and data collection, it was carried out the study of the pedagogical project of the course and the completion of a short course for the use of GeoGebra software designed for 21 students enrolled in plane geometry discipline.We used as research tools two diagnostic questionnaires, observation and photographic record. Analysis of the results showed that students in the degree course were receptive to the use of GeoGebra software in the classroom, and the short course and teaching activities applied had a great level of acceptance by the future teachers of mathematics.The conclusions point out that the use of GeoGebra software should be understood as an alternative teaching tool for teaching Geometry in order to provide the student a dynamic, interactive and fun method for learning mathematics.
