Vận dụng mô hình 5E trong dạy học định lí “Tổng các góc của một tứ giác” (Toán 8) nhằm phát triển năng lực tư duy và lập luận toán học cho học sinh

Tóm tắt

The 5E teaching model is a modern teaching method based on constructivist theory, aiming to promote active participation and develop critical thinking in learners. The learning process is organized into closely linked phases, creating conditions for students to independently explore, construct knowledge, and apply it into practice. This study presents the basic characteristics of the 5E teaching model, analyzes its impact on the development of students' mathematical thinking and reasoning competencies through manifestations such as “performing thinking operations”, “logical reasoning”, and “asking and answering questions”. Subsequently, the researcher illustrates the application of this model in teaching the theorem “Sum of angles of a quadrilateral” (Mathematics 8). The 5E model offers opportunities to create a favorable learning environment for students to actively participate in thinking activities, gradually forming and consolidating mathematical reasoning. The teaching phases are designed to help students easily transition from visual experience to knowledge generalization, thereby enhancing their ability to explain and apply mathematical knowledge to problem-solving.
