Situações desencadeadoras de aprendizagem para o ensino de trigonometria

Abstract

This work was developed in order to reduce the difficulties of 2nd year high school students with the subject of trigonometry, its main objective is to propose learning triggering situations (SDA), which were planned according to Vigotski’s cultural historical theory, which emphasizes that the student’s cognitive development takes place through social interaction, that is, through their interaction with other individuals and with the environment. The SDA were prepared with the intention that students, solving the proposed situations, can, with the mediation of the teacher, develop theoretical thinking, build and formalize the trigonometric concepts, in addition to addressing a little history of trigonometry, where students can understand the necessity of its emergence. The work is qualitative in nature, as it will investigate how learning will take place through triggering situations. It was not possible to implement the activities due to the Coronavirus pandemic.
