Dạy học theo định hướng giáo dục STEM dựa trên mô hình 5E chủ đề “Tính đối xứng của hình phẳng” (Toán 6) nhằm phát triển năng lực giải quyết vấn đề toán học cho học sinh

Tóm tắt

Within the context of the 2018 General Education Program, which emphasizes the development of problem-solving competency and STEMbased learning, this study designs, implements, and preliminarily evaluates a STEM teaching sequence based on the 5E model for the topic “Symmetry of Plane Figures” (Grade 6 Mathematics) to develop students’ mathematical problem-solving skills. The study employed a mixed-method approach with a pre-post design involving 94 sixth-grade students at Quang Trung Secondary School (Gia Lai). Data were collected through observation checklists, product assessment rubrics, problem-solving competency rubrics, and pre- and post-tests. Results indicate that students showed positive improvements in problem identification, proposing and implementing solutions, as well as evaluating products. The STEM teaching sequence centered on Mathematics not only increased students’ learning motivation but also significantly enhanced the components of mathematical problem-solving competency, providing preliminary evidence for the feasibility of the model.
