在初中数学教学中,如何加强概念课的教学,笔者通过十多年的教学实践,有几点粗浅体会,简述如下,以供参考。 一、讲准 在进行数学概念的教学时,讲的写的都要准确。例如不要把非负数说成是正数,不要把除和除以相混淆。有人把分数3/4理解为就是3÷或3:4,有人把平行线的定义写成:“两条不相交的直线”,甚至还有把零指数幂的定义当做定理来证明,等等,都
In junior middle school mathematics teaching, how to strengthen the teaching of the concept lesson, the author through a decade of teaching practice, there are several superficial experience, briefly described below, for reference. First, be accurate When teaching mathematics concepts, the written statements must be accurate. For example, don’t say non-negative numbers as positive numbers, and don’t confuse dividing and dividing. Someone understands the score 3/4 as 3 or 3:4. Some people write the definition of the parallel line as: “Two disjoint lines”, and even the definition of the zero exponent power as a theorem, etc. All
