A tecnologia como ferramenta para superação das deficiências da base e otimização da aprendizagem em matemática: uma experiência com os números racionais

Abstract

The present work deals with the technology as a tool to overcome the deficiencies of the base and optimization of learning in mathematics. For both, it was a theoretical research based on reading of several authors and official documents such as the National Curriculum Parameters - PCNs, followed by an Experimental Study applied to a group of students from 1 years of Middle School Vivina Monteiro. In the first part, we tried to reflect the teaching-learning process of mathematics, as well as, the importance of this discipline and its function in the context of Basic Education. In addition, we sought to identify the guidelines and recommendations of experts in the area of the main resources that can contribute to improving the performance of students of mathematics in this phase of schooling, in particular, the technological resources. The approaches for reflexion follow a logic that contemplate since pedagogical aspects more holistic, related to the purpose of the teaching of mathematics in high school, through analysis of the possibilities, limitations and potential of technological resources in the current society, and culminates with the study more specific characteristics of Rational Numbers, curricular component selected for application of the case study. The central objective of the research is limited with the proposal of this work which is to offer students admitted in middle school an alternative to overcome the deficiencies of learning in mathematics, in particular those resulting from the previous step: Elementary Education. For this reason, it has been the use of technological resources such as video-lectures, internet gaming and applications of Educational Linux. It also aims to create a culture of study of science using these resources to produce favorable results. The second part, i.e. , the study applied to participating students, is to enable the Commission to determine the confirmation of two hypothesis, namely: It is possible to overcome the deficiency of the base using the technological resources and overcoming these deficiencies optimize the learning of mathematics in High School. To confirm these hypotheses, was drawn up and applied instrumental at the beginning and at the end of the study, as tests contemplating a list of competencies/skills previously defined, tabulated compared. The results demonstrated the effects of applications used, highlighted the potential of these resources as efficient tool to support the teaching-learning process of mathematics.
