Thiết kế bài toán thực tiễn trong dạy học môn Toán: Trường hợp chủ đề “Giá trị lớn nhất, giá trị nhỏ nhất của hàm số” (Toán 12)

Tóm tắt

Teaching Mathematics not only focuses on equipping knowledge but also developing learners' competencies, helping them apply mathematics into real life. In particular, practical problems act as a “bridge” between theory and practice, between mathematical knowledge and real-life situations; contributing to the development of students' mathematical competencies, logical thinking and the ability to apply interdisciplinary knowledge. The study proposes a process of designing practical problems in teaching the topic “The largest value, the smallest value of a function” (Math 12) and illustrates this process through designing specific practical problems. In the process of teaching Mathematics, teachers need to proactively design and exploit practical problems in relation to the lesson content, creating favourable conditions for students to experience, explore and apply the learnt knowledge to solve practical problems. At the same time, linking the learning content with a practical context will help students understand deeply and retain the knowledge for a long time; thereby, contributing to improving Mathematics teaching quality and developing students’ comprehensive competencies.
