函数教学是中职数学教学的重点和难点,在教学中,教师要十分重视这部分内容的教学,然而教学效果总不理想,这是教学思想和教学方法不适合中职学生的实际情况造成的.在教学中,教师要使学生认清函数的本质,通过学习使学生可以利用函数知识有效地解决实际问题,使学生在具体应用中不断加 Function teaching is the key and difficult point of secondary mathematics teaching. In teaching, teachers should attach great importance to the teaching of this part. However, the teaching effect is not ideal. This is caused by the fact that teaching ideas and teaching methods are not suitable for secondary vocational students In teaching, teachers should make students recognize the essence of the function, through which students can use function knowledge to effectively solve practical problems, so that students continue to increase in specific applications
