函数教学在整个数学体系中占有重要的位置,而且很多理科的学科中都涉及函数知识,所以说数学学科中的函数教学具有非常重要的意义。初中数学中的函数是学习函数的基础,在初中函数的学习中,教师不仅要教会学生基本的函数知识,同时还要提高学生学习函数的能力。引导法主要是通过教师的引导来完成教学,在引导教学模式中,学生处于主导地位,教师需要通过适当的引导来帮助学生完成学习,从而提高学生的自主学习能力。 Function teaching occupies an important position in the whole mathematics system, and many science disciplines involve function knowledge, so it is of great significance to teach function teaching in mathematics. The function of junior high school mathematics is the basis of learning function. In junior high school function learning, teachers should not only teach students basic functional knowledge, but also improve the ability of students to learn the function. The guiding method is mainly through the guidance of teachers to complete the teaching. In guiding teaching mode, the students are in the leading position. The teachers need to guide students to complete the learning through appropriate guidance so as to improve the students’ autonomous learning ability.
