Ensino da função seno através do phet interactive simulations: uma sequência didática para análise da contribuição de um laboratório virtual para a aprendizagem da matemática

Abstract

The objective of this work is to evaluate the effectiveness of a didactic sequence focused on teaching the sine function using the virtual mathematics laboratory PhET Interactive Simulations. The virtual environment utilized was the Trigonometric Tour animation, which belongs to the PhET Interactive Simulations laboratory at the University of Colorado in Boulder, United States. The results revealed that the majority of participating students successfully learned the content related to the sine function, achieving an impressive 90% accuracy on the test administered after completing the activities. This demonstrates the success of utilizing the mentioned virtual mathematics laboratory to facilitate dynamic and meaningful learning of the mathematical content in question. Furthermore, it highlights that effective teaching can be achieved through a playful and enjoyable methodology without incurring significant costs, as the PhET Interactive Simulations Laboratory, along with various other digital platforms, is freely accessible.
