Dạy học giải bài tập toán nội dung “Hệ thức lượng trong tam giác” (Toán 10) thông qua tranh luận khoa học nhằm phát triển năng lực giao tiếp toán học cho học sinh

Tóm tắt

According to the 2018 General Education Program for Mathematics, mathematical communication competence is one of the five core components of mathematical competence that need to be formed and developed for high school students. Therefore, in teaching Mathematics, teachers need to focus on developing mathematical communication competence for students, meeting the requirements of current educational innovation. The study proposes a scientific debate process in teaching Mathematics to develop mathematical communication competence for students and illustrates this process in teaching and solving mathematical exercises on the content of “Triangle relations” (Math 10) at An Lac High School, Binh Tan District, Ho Chi Minh City. With the topic “Triangle relations” in the 10th grade program, the calculation of side and angle lengths through the sine theorem, cosine theorem and their consequences has been built by us through math problems to create a positive interactive learning environment, promoting the development of mathematical communication competence for students.
