Uma proposta híbrida de ensino para o estudo da função quadrática

Abstract

Technology is increasingly present in the daily life of the school, whether in the hands of students or as a resource acquired by the school, in order to make the contents more attractive, making learning easier and more stimulating. With this work, we seek to model everyday situations, where concepts about quadratic functions are used. In this perspective, the research aims to build and apply a didactic sequence for the study of quadratic functions, based on Blended Learning, with the help of technological resources and concrete materials. The didactic sequence on quadratic functions will be developed in the design of the educational product of this work, being useful to several mathematics teachers or related areas that want to use this methodology, even with other subjects. The research has a qualitative and exploratory nature., making use of a hybrid methodology, semi-presential teaching, and the ICT's, with the purpose of improving the students' ability in a transition between the concrete and the abstract, with problems involving graphics and maximum and minimum functions quadratic, but always leaving students in a leading role, as it is the basis of active methodologies. The developed material was applied to high school and elementary student volunteers in five face-to-face meetings, where three questionnaires were used, the Geogebra application as an aid, in addition to all the research being conducted along the lines of Blended Learning. Throughout the application of the research, it is possible to perceive a gain in students' learning about the content worked on, evidencing the effectiveness of the application of Blended Learning. Details that are possible to go unnoticed in a Traditional Teaching, but could be evidenced and much more explored. Thus, such research will motivate other teachers to use the hybrid methodology in their classes.
