This present work aims to verify: as compatible constructivist perspectives of learning with the planning of Trigonometric Functions; teaching the as researches in mathematics education field , which brings important results on the learning process may contribute to the organization of the Trigonometric Functions teaching that leverage best learning situations for students, as the performance of teachers of mathematics is revealed, with regard to planning activities in the teaching of Trigonometric Functions, consistent with a constructivist view of learning. We developed a qualitative study with two teachers and 70 students from the 2nd Grade of high school in a public school in the State of São Paulo. Its theoretical work of Simon (1995) on the use of HLT in teaching mathematics to formulate models of teaching based on constructivism. As a component of the Mathematics Teaching Cycle developed by Simon, the elaborate HLT was made use of the research findings for the development of Trigonometric Functions through activities and solve problems involving: constructions with ruler and compass, manipulative material, scientific calculator, construct graphs using software GeoGebra and paper and pencil. The results led us to conclude that the use of research contributes to the education organization of Trigonometric Functions; however you must provide access to such teachers to such research. Although the HLT are potentially rich, complex is the task of developing activities to accomplish a constructivist learning perspective. We note that participation in tasks involving the use of technology and material handling enhances the learning of Trigonometric Functions. However, the HLT is not prepared enough for learning to occur, because the teacher performance has a decisive role in mediating the construction of knowledge of the students. In the same way we experience the interaction and participation between students and teacher which is essential for learning
