Thiết kế tình huống dạy học nội dung “Giải hệ phương trình bậc nhất hai ẩn” (Toán 9) theo bối cảnh với phương án REACT nhằm nâng cao năng lực mô hình hóa toán học cho học sinh

Tóm tắt

In current mathematics education, mathematical modeling competence is considered one of the core competences that need to be developed for students, helping them solve practical problems. Teaching Mathematics in context with the REACT method includes 5 integrated learning styles: Association, Experience, Application, Cooperation, and Transformation; meeting the requirements of current educational innovation. This study focuses on designing teaching situations associated with the content “Solving systems of first-degree equations with two unknowns” (Math 9) in the context with the REACT method to develop mathematical modeling competence for 9th grade students. In this study, we use the design-based research method to build a teaching design process in a practical context with the REACT method and illustrate the process through designing a teaching situation, close to students' lives. Applying the proposed teaching situation design process not only aims to improve students' understanding of systems of equations but also helps them develop analytical skills, critical thinking and the competence to apply mathematics to life.
