Desenvolvimento e aplicação de uma sequencia didática com foco nas relações matemáticas que englobam leis físicas

Abstract

The main objective of this work is to develop a teaching method using practical experiments involving associations between physical quantities so that high school students construct the meaning of the studied phenomena and how they are represented as mathematical relations of direct proportion and square law. Based on the theoretical conceptions of Zabala, Bloom and the material created by the PSSC. The teaching method is a didactic sequence composed of eleven classes .Classes one through four, deals with the construction of the concepts of measure and magnitude, classes five through eleven with the construction of proportionality relations between quantities and their graphical representations. The application of the educational produtc occurred in six classes of first year of high school in a state school in Juiz de Fora - MG and, through them, we observe the great interest of the students in participating in the experimental activities, because they differ from the lectures. We can also highlight a better understanding of the contents worked. Analyzing the obtained results, we could show that experimental activities are of vital importance in the students' learning process because they make the connection between the concrete and the abstract. The didactic sequence is described in Chapter 5, the application is reported in Chapter 6, and the formatted product for support and application is set out in Appendix A
