从初中开始,学生就有了关于函数概念方面的学习,高中的函数教学也是高中数学的一个重点学习内容,在升入大学之后,学校仍然开设有数学函数课程.另外,在之后的日常生活和学习以及工作中,函数也有大量的应用.这足以看出函数在学生的学习生涯中的重要地位.高中时期的学生思维方式还没有完全的成型,因此,在教学中,教师的引导作用起了很大的作用.尤其是在高中函数的教学中,作为一个考试中的重点和难
Since the beginning of junior high school, students have studied the concept of function, and high school’s function teaching is also a key learning content of high school mathematics. After entering university, the school still has a math function course. In addition, There are also a large number of applications of functions in study and work, which is enough to see that the function plays an important role in the students’ learning career. The thinking mode of students in high school has not been fully formed yet. Therefore, in the teaching, A great role, especially in the teaching of high school function, as an examination of the focus and difficulty
