Thiết kế bài toán thực tiễn trong dạy học nội dung “Tính chất ba đường trung trực của tam giác” (Toán 7) theo lí thuyết giáo dục toán học gắn với thực tiễn (RME)

Tóm tắt

The Theory of Realistic Mathematics Education (RME) was born in the Netherlands based on Freudenthal's two core views: mathematics is closely linked to practice and mathematics is a human activity. Accordingly, the RME Theory is consistent with the view of the 2018 General Education Program in Mathematics, which is to create a connection between mathematics and practice. The study proposes a process for designing practical problems in teaching the content “Properties of three perpendicular bisectors of a triangle” (Math 7) according to the RME theory and illustrates this process through designing a specific practical problem. The experimental results of teaching and solving the designed practical problem show that the design process is reasonable and feasible in teaching. The methods used in the study are theoretical research and experimental research to clarify the concept of RME theory, principles, process of designing practical problems and organizing experiments.
