A teaching guide on computer applications of quadratic function modeling in mathematics

Abstract

The present work aimed to design a Teaching Guide on computer applications of the quadratic function modeling in Mathematics, to achieve better results in the teaching and learning of mathematics by integrating the computer technology in
the classroom, as well as the development of new skills, such as modeling. So, the proposal will provide teaching resources
to educators and students of third year of general Secondary Education to support the subject content of the quadratic function. From the psychological field, such a proposal is based on Ausubel´s meaningful learning and Vygotsky´s Psychosocial
Theory. From the technological aspect, it follows Cabero´ and Marqués´ proposals. The methodology is consistent with a feasible project model, executed in three phases: Diagnostic, design and feasibility of the guide. Diagnosis and feasibility were supported by a document analysis and a questionnaire was applied to a sample of teachers selected intentionally, to gather
data. The guide was designed in two modules, one for teachers and the other for students, to serve as a learning support of
the quadratic function through its application in Mathematical modeling, providing a clearer interpretation of different representations of a function: Analytical, algebraic, tabular and geometric, in addition to exploration, experimentation and formulation of conjectures, within an interactive learning environment.
