It shows the control steps to maximize the student learning and exposes trigonometry lessons, based on Mental Actions Formation Theory containing: definitions, how to show them to the student, activities and exercises. These are designed to match theory and practice through the process of pedagogic psychology. The theoretical substantiation revolves around renowned authors such as: Van de Walle (2009); Vigotsky (2007); Galperin (2009) and Talizina (2000). This research concludes that there are many reasons to use the pedagogic psychology in mathematics lesson proposals, especially, in trigonometry teaching in high school.Acesso AbertoEnsinoPsicologiaTrigonometriamasterThesisCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICA: MATEMÁTICA EM REDE NACIONAL
