Abstract

Dynamic geometry system has been promoted actively in mathematical education because of its potential to comprehensively improve the core mathematical literacy required in an increasingly technology-based society. The ability to dynamically drag geometric elements to compare and discover relationships, and the ability to control movements and observe trajectory, are what make dynamic geometry system a powerful and efficient mathematical learning tool. This paper focuses on the application of dynamic geometry systems in inquiry-based maths education in middle school. Specifically, an inquiry-based learning activity named “mathematically drawing flowers with NetPad” is designed for students to study a characteristic feature of rose curves, i.e., the relationship between the number of petals and coefficient of rose curve equation. By sequentially graphing equations \(\rho = A \cdot cos(n\theta )\) and \(\rho = A \cdot cos(n\theta ) + B\) with NetPad in a constructive way, and then observing, reasoning, verifying, and expressing, students can closely experience a complete generating process of maths knowledge, and further improve their innovation awareness and practical ability.
