The study of functions in high school: an alternative proposal

The focus of this book is therefore on high school algebra, more specifically on the topic of functions. This subject was chosen because we understand that a more 'traditional' approach to mathematics, which emphasizes formulas over understanding, can create significant learning difficulties, leading us to seek ways to teach algebra in a more meaningful and engaging way. In this sense, this work is structured in five chapters. The first three chapters discuss the theoretical basis that supports the alternative activities developed for teaching functions at the secondary level. The fourth chapter presents the practical part of the work, focusing on activities designed for teaching and learning functions at the secondary level. Finally, the book concludes with some final thoughts, in which we emphasize that the proposal presented in this book represents a rich and challenging learning context for both students and teachers.
