Dạy học định lí hình học ở trung học cơ sở theo mô hình dạy học kết hợp với sự hỗ trợ của GeoGebra

Tóm tắt

In the context of current educational innovation in general education, the application of information technology in teaching is not only an inevitable trend but also an urgent requirement to improve the quality of teaching and developing students' competence. In particular, in teaching Mathematics, teaching geometric theorems based on traditional methods with lectures and drawings on the board will make it difficult for students to visualize and lack of interest in learning. This study proposes a process for teaching geometric theorems in middle school according to a teaching model combined with the support of GeoGebra and illustrates this process in teaching a geometric theorem in grade 8. To effectively implement the teaching model combined with the support of GeoGebra in teaching geometric theorems, teachers need to clearly define the lesson objectives and choose appropriate content to integrate technology, avoiding abuse or using GeoGebra in a formal way. In addition, teachers need to master the GeoGebra tool and know how to design interactive and intuitive learning activities to help students actively explore, discover and prove theorems.
