Dạy học ứng dụng “định lí Sin” vào giải các bài toán thực tiễn nhằm phát triển năng lực giải quyết vấn đề toán học cho học sinh trung học phổ thông

Tóm tắt

Mathematics education contributes to the formation and development of students' key qualities, general and mathematical competences. In particular, the competence to solve mathematical problems is one of the core elements of mathematical competences, helping students develop core knowledge and skills and creating opportunities for students to experience and apply mathematics into practice. The research proposes a teaching process to apply the law of sines to solve practical problems to develop mathematical problem- solving capacity for high school students and illustrate this process through solving specific problems. The research method used in the article is theoretical research. Applying the proposed process into teaching practice shows that students appear excited and active in the learning process as well as develop components of mathematical problem-solving competency.
