Đề xuất biện pháp sư phạm phát triển tư duy thuật toán cho học sinh trong dạy học chủ đề “Phương trình bậc hai một ẩn” (Toán 9)

Tóm tắt

Algorithmic thinking plays an important role in developing mathematical thinking and problem-solving competence in lower secondary mathematics education. This study aims to clarify the theoretical foundations of algorithmic thinking, identify its components and manifestations among lower secondary students, and propose pedagogical measures for developing algorithmic thinking in Grade 9 students through teaching the topic of quadratic equations in one variable. Based on the identified components of algorithmic thinking, four pedagogical measures were proposed to support students in analyzing mathematical problems, constructing and organizing solution procedures, selecting appropriate strategies, and representing algorithms through flowcharts and simple Python-based activities. The study contributes to clarifying the relationship between algorithmic thinking components and instructional activities, while providing pedagogical measures that support mathematical problem solving within a competency-based educational approach in lower secondary mathematics teaching.
