Vận dụng mô hình 5E trong dạy học giải các bài toán thực tiễn ở lớp 8 bằng Định lí Thales

Tóm tắt

Teaching according to the 5E model requires that students follow five stages of learning, all starting with the letter “E”. In each learning stage, students are motivated internally, to independently create and master knowledge and learning skills. Thales' theorem in the 8th grade Math curriculum is important geometric content, with many applications such as: calculating the sides of a triangle through similar triangles; Calculating the height of an object without directly measuring that object, etc. This study presents the process to apply “Thales' Theorem” to solve practical Math problems according to the 5E model and illustrates this process in solving specific problems. Applying the 5E model in teaching in high schools helps teachers easily identify the focus of the lesson, guiding students through the learning stages systematically; thus, creating opportunities for students to form and develop necessary competencies.
