摘要
board for mathematical and technical-scientific learning, it is a physical instrument of didactic-pedagogical nature that aims to promote the necessary understanding and mastery of operations with complex numbers by high school and university students, in a non-algorithmic way, aiming at an appropriation of the alternating current electrical circuits. the differential of the board is to innovate the teaching of complex numbers by ways that make sense to the user, modifying old customs such as the use of scientific calculators that limit the range of mathematical concepts and, consequently, compromise specific learning in circuits. alternating currents. this instrument favors the teaching of complex numbers aiming at learning in electricity, since this mathematical content presents limitations in the understanding of students in alternating current electrical circuits which, in turn, depend directly on the domain and understanding of the mathematical content of complex numbers , thus compromising that learning. generally, as an alternative, some teachers resort to the use of the scientific calculator, which already transform the rectangular coordinates of complex numbers into values described in the form of a vector with an angle, that is, the polar form. the use of the calculator thus employed promotes the mechanization of undesirable learning, especially since students, in general, do not reach desired stages of understanding for future use in other contexts. in this sense, the board promotes the necessary understanding and mastery of operations with complex numbers, aiming at appropriating the content of alternating current electrical circuits.
