函数就像一根红线贯穿在高中数学中.函数知识的教学首先在初中阶段,学生初步掌握了函数的定义与函数的表示方法,并研究了一些常见的函数,对函数知识有了初步的感性认识.到了高中阶段,学生进一步学习了集合、映射等数学概念后,就能运用集合、对应思想来归纳函数的定义.这样,学生更加深刻地理解了函数的实质.函数以其独特的艺术形式成为高中数学知识的精品.一、衔接好初高中知识,填补教材编写中的空白
The function is like a red line running through high school math.First, in the junior middle school, the students mastered the definition of the function and the representation of the function, and studied some common functions, which have preliminary sensitivity to the function knowledge Understanding.At high school stage, students further learn the mathematical concepts of set, mapping, you can use the set, corresponding to the idea to summarize the definition of function.Thus, students understand the essence of the function more deeply.Functions in its unique art form Become a high school mathematics knowledge boutique. A good convergence of early high school knowledge, to fill gaps in the preparation of textbooks
