“空间与图形”是初中数学的重要内容.笔者通过调查发现,学生在此内容的学习中存在较大的困难,本文对此现状进行分析,并提出几点教学建议.一、重视概念学习数学概念是人类对现实世界的空间形式和数量关系的简明概括及反映,它是数学学科的精髓,是学生进行计算、证明的依据,也是培养学生思维能力的良好素材.学好概念是学好“空间与图形”的基础.1.增强直观性,形成感性认识“空间与图形”将逻辑性与概念性相结合,由生产生活中的实际几何模型,抽象出教
“Space and Graphics ” is an important content of junior high school mathematics.The author found through investigation that students have great difficulty in the content learning, this paper analyzes the status quo, and puts forward some teaching suggestions. Learning mathematics concept is a concise summary and reflection of mankind’s relationship between spatial form and quantity in the real world.It is the essence of mathematics discipline and is the basis for students to calculate and prove.It is also a good material to develop students’ The basis of “space and graphics” .1 enhance intuition, the formation of perceptual knowledge “space and graphics ” the combination of logic and conceptualization, from the actual geometric model of production and life, abstract education
