人们对于“圆”很熟悉,它是平面几何图形。而日常生活中,篮球常常也被人们描述为“圆圆的”。在这两种表述中,“圆”的内涵是不相同的。但在课堂上,学生容易将之混为一谈。在教学中,像这样数学语言与日常生活用语相冲突的情况时有发生,教师该如何处理呢?作为一线教师,我认为应基于数学本质来处理教学细节。 People are familiar with “circle ” and it is a flat geometry. In everyday life, basketball is often described by people as “round”. In both expressions, the connotation of “circle” is not the same. But in class, students can easily mix it up. In teaching, situations such as the conflict between mathematical language and everyday language have taken place and what should teachers do? As a front-line teacher, I think the teaching details should be handled based on the nature of mathematics.
