Dạy học giải bài toán chủ đề “Hàm số bậc nhất” (Toán 8) với sự hỗ trợ của phần mềm GeoGebra nhằm phát triển năng lực giải quyết vấn đề toán học cho học sinh

Tóm tắt

In the context of digital transformation in education and the implementation of the 2018 General Education Program for Mathematics, the use of mathematical software to support competency-based teaching is becoming increasingly necessary. This paper proposes a teaching process for solving problems on the topic of "Linear Functions" (Mathematics 8) with the support of GeoGebra software to develop students' mathematical problem-solving competence. The paper is conducted using a qualitative method through the analysis and synthesis of theoretical documents, the 2018 General Education Program for Mathematics, and research on GeoGebra, teaching problem-solving in mathematics, and mathematical problem-solving abilities. The proposed teaching process consists of four steps, clarifying the role of GeoGebra in visualizing knowledge, supporting students in exploring and verifying hypotheses, analyzing results, and selecting solutions to problems. This article contributes to providing a theoretical basis for teachers in organizing problem-solving lessons in Mathematics, oriented towards developing problem-solving competence in the context of digital transformation.
