数学概念教学是学生掌握数学基础知识和基本技能的核心,正确理解数学概念是学好数学的基础。近年来,我对各年级的期中、期末考试卷进行分析时,发现有相当一部分学生的错误都落在概念上,特别是有些优等生在运用概念进行判断、填空时也出错,随着年级的升高,所学概念的增多,在概念处的错误比例也逐渐递增,可见学生对概念内涵的理解和把握不完善,灵活运用不够。并且在许多概念课的公开教学中,我发现老师在概念教学中孤立地
Teaching of mathematical concepts is the core of the students to master the basic knowledge and basic skills of mathematics, to correctly understand the mathematical concepts is to learn mathematics. In recent years, when I analyzed the middle and final exams for all grades, I found a considerable number of students’ mistakes fell into the concept. In particular, some top students made judgments in applying concepts and made mistakes when filling out the blank. As the grade Increased, the concept of learning increased, the proportion of errors in the concept of gradual increase, showing that students understand the concept of connotation and imperfect, not enough flexibility. And in the open teaching of many concept classes, I found that teachers are isolated in concept teaching
