数学概念是构成数学教材的基本结构单位,是学生学习的主要知识,是应用数学与学生进一步学习的基础。学生只有建立起正确明晰的概念,才能牢固地掌握基础知识。因此概念教学是初中数学教学中至关重要的一项内容,是基础知识和基本技能教学的核心。在教学实践笔者发现,一些学生数学素养之所以差,概念不清往往是最直接的原因,因此造成他们在对数学概念的理解、应用和转化等方面的差距明显。概念课的教学,一种常用的模式:通过大量具体的实际例
Mathematical concepts constitute the basic structural unit of mathematics textbooks, is the main knowledge of student learning, mathematics and applied learning is the basis for further learning. Students must have a solid grasp of the basics only if they have established a correct and clear concept. Therefore, the concept of teaching is a crucial part of junior high school mathematics teaching is the core of basic knowledge and basic skills teaching. In the teaching practice, I found that the reason why some students have poor math qualifications and unclear concepts is the most direct reason, so they have obvious differences in comprehending, applying and transforming math concepts. Concept class teaching, a commonly used model: through a large number of concrete practical examples
