Exploring with digital media to understand trigonometric functions through periodicity Periodicity for meaning making in Trigonometry

Résumé

Trigonometry consists of a multifaceted mathematical field whose fundamental concepts, sine and cosine, have many different representations, some of them approached throughout secondary education. Unfortunately, many of its aspects are taught individually, leading students to make isolated, unconnected meanings on them. This empirical study discusses an alternative view towards trigonometry, in an attempt to create connections among the different aspects, under the scope of one meaningful context; that of periodicity. The use of digital media enables the application of this unconventional proposal, through a set of specially designed activities. In this paper we present a brief description of the main study-in-progress, as well as the results gained by its first implementation to 9th- Grade students, in terms of their meaning making on trigonometric concepts.
