Sử dụng biểu diễn toán học trong dạy học “Giới hạn hữu hạn của hàm số tại một điểm” (Toán 11)

Tóm tắt

The concept of “the Limit of a function” is a fundamental element in the high school mathematics curriculum and serves as an important premise for a deeper understanding of topics such as “Continuous functions” and “Derivatives and Integrals”. However, the abstractness and complexity of limits often cause great difficulties for 11th grade students. To overcome these difficulties, the use of mathematical representations in teaching is considered an effective measure. The study proposes a process of using mathematical representations in teaching mathematics and applying it to teaching the concept of “Finite limit of a function at a point” (Mathematics 11). The aim is not only to help students deeply understand this concept, but also to improve their ability to apply it to solving relevant problems. The application of the mathematical representation process is not only effective in teaching mathematics, but also opens up the possibility of application in other natural sciences.
