Two days with didactics of mathematics: Encouraging teaching of the cosine theorem Two days with didactics of mathematics: Constructivist approach to teaching of the cosine theorem
2021
Abstract
During the workshop we will focus on the cosine theorem. Constructivist approach to teaching the cosine theorem is based on the diploma thesis in which I dealt with the cosine theorem, and is continuously changed by the experience with teaching trigonometry at the secondary school.
We will also focus on a constructivist approach to deriving a cosine theorem, which in my experience is friendly to pupils. I will send a series of assignments for pupils on the topic of discovering a cosine theorem.
I assume that we also spend some time sharing other experiences with the cosine theorem.
