Desenvolvimento de um objeto de aprendizagem para o ensino de Trigonometria

Abstract

This article shows the results achieved with the implementation of the learning object, developed with Microsoft Power Point and accessed via the web browser, the teaching of trigonometry in the component content of mathematics curriculum for students in 2nd grade of high school. This learning object was planned and organizes by the class teacher and student of specialization in Media in Education. From the observation of students by this course participant, regarding the understanding of the content mentioned above, there was a concern to organize a learning object to motivate the teaching of trigonometry to those students and get more time. The project was developed in two phases: In the first one the content has been traditionally explained by relating the functions sine, cosine and tangent in the trigonometric cycle - manual built-mind - and the table of trigonometric ratios without the use of computers, software and Internet. In the second phase students surfed in the learning object where the content was organized with a visual language easy to understand that at any given time, they were instructed to build the same table of trigonometric ratios using spreadsheets and multimedia features. The organization of the learning object has a tutorial structure, leaving the challenge of making a new application version with more features multi media. It was felt that the application is effective in teaching trigonometry.
