Thiết kế bài toán thực tiễn trong dạy học môn Toán nhằm phát triển năng lực mô hình hóa toán học cho học sinh trung học cơ sở

Tóm tắt

The 2018 Math general education curriculum not only focuses on equipping learners with content knowledge but also creates opportunities for students to experience and apply mathematics into practice. Mathematical modeling competence helps learners turn a practical problem into a mathematical problem through mathematical models such as equations, graphs, charts, functions, etc. Through solving real problems, students develop learning competence, especially mathematical modeling competence. However, designing practical problems is a challenge for teachers in ensuring teaching content, practicality of data, and accuracy of data. The study proposes a process for designing practical problems in teaching Thales's theorem for 8th grade students. A teaching experiment has been implemented to test the accuracy of the designed and calculated practical problems. reasonableness of the facts. Experimental results show that the designed practical problems are feasible and suitable for practice and teaching content.
