数学概念在数学教学中有着极其重要的地位,正确理解数学概念是掌握数学知识的前提,也是提高解题技能的关键。 一、引入概念的方法 1.直接引入 如学习幂函数的概念时可直接给出它的定义:“一般地,Y=X~α叫做幂函数,其中X是自变量,α是常数”。然后做以解释,学生就会很容易接受。
The concept of mathematics has an extremely important position in mathematics teaching. Correct understanding of mathematical concepts is a prerequisite for mastering mathematics knowledge, and it is also the key to improving problem-solving skills. First, the introduction of the concept of the method 1. Directly introduced As the concept of learning the power function can be given directly to its definition: “Generally, Y = X ~ α is called a power function, where X is an independent variable, α is a constant.” Then explain it, students will be very easy to accept.
