Teacher training and the use of Learning Objects in Trigonometry

It is impossible to deny the potential of computers to facilitate simple day-to-day procedures. What we see is the constant modernization of society, with increasingly advanced technologies. In view of this, it is important that teachers reflect, rethink their practice and build new forms of action that allow them not only to deal with this new reality, but also to build it. This book aims to develop a critical-reflective study about the use of Learning Objects in Trigonometry, emphasizing the teacher training for the use of these new technologies in teaching. The theoretical foundation of this research is based on the studies developed by some educators and researchers who have given special attention to computer-assisted teaching, and on the work done with 60 undergraduates of the seventh semester of the course of Full Degree in Mathematics of the State University Vale do Acaraú - UVA, who knew the concept, the applicability and the use of Learning Objects allowing them, still in their academic training, to have contact with a different way of teaching, leaving the sameness of classical classes and emerging to more technological classes.
