Dạy học giải toán nội dung “Các phép toán trên tập hợp” (Toán 10) thông qua tranh luận khoa học: một nghiên cứu trường hợp

Tóm tắt

According to the 2018 General Education Curriculum for Mathematics, mathematical communication competence is one of the five core elements of mathematical competency to be formed and developed for high school students. Therefore, in teaching Mathematics, teachers need to focus on developing students' mathematical communication competency. This study proposes a process for teaching math problem solving through scientific debates to develop students' mathematical communication competency. This process is illustrated in teaching math problem solving with the topic “Math operations on sets” (Math 10) at Nguyen Huu Huan High School, Ho Chi Minh City. The study puts students in the context of calculating the number of elements of a set through the stages of a scientific debate, allowing students to share ideas about solutions to problems, present mathematical arguments, give feedback and refute incorrect statements to promote the development of the four components of mathematical communication competency.
