A importância do ensino de números complexos no ensino médio, na visão dos professores de matemática, em alguns municípios da região oeste do Paraná

Abstract

This work aims to identify the view of high school mathematics teachers in relation to the importance of teaching the content of Complex Numbers in High School. In the methodological approach, qualitative research was chosen through the analysis of questionnaires applied to mathematics teachers who work in the State Education Network in some municipalities in the western region of Paraná. Through this research, we observed that the majority of respondents consider it relevant to teach the set of Complex Numbers for high school students, because if it is not worked, it will cause some kind of prejudice to the student. It was possible to observe that the set of Complex Numbers does not appear in the content matrix of the National High School Examination (ENEM), but it is part of the teaching curriculum and is present in most vestibular studies. Eventually the unconcern of this transfer of content is contested by the teachers, due to its little applicability in the daily life of the student.
