Đề xuất quy trình ứng dụng Desmos trong dạy học chủ đề “Dao động” (Vật lí 11) theo hướng phát triển năng lực nhận thức vật lí của học sinh

Tóm tắt

In the context of the 2018 General Education Curriculum, which requires innovation in teaching methods to promote student competency development, integrating technology into physics instruction has become essential. Desmos is a graph visualization tool that helps students approach complex physics concepts more effectively. This paper proposes a process for applying Desmos in teaching the topic of “Oscillations” (Physics 11) to develop students' cognitive competencies in physics. Specifically, it focuses on the design and application of Desmos in teaching, including steps for designing lesson frameworks, selecting learning materials, using Desmos in the classroom, and collecting and assessing students’ learning outcomes. The results show that Desmos aids students in visualizing physical quantities such as amplitude, period, and energy transformation. It also enhances their analytical and logical reasoning skills through interaction with dynamic graphs. Desmos not only meets the demand for innovative teaching methods but also fosters students’ proactivity and develops their cognitive competencies in physics, particularly with abstract concepts like oscillations. However, to achieve optimal effectiveness, teachers need to prepare thoroughly and adapt their teaching methods to suit different groups of students.
