函数是初中数学教学的重点和难点,学生对函数知识掌握得好坏情况对学生今后的函数学习有着重要的影响.通过初中函数的教学,可以培养学生观察问题、分析问题、解决问题的能力,对学生数学学习习惯的培养也有一定的帮助.初中函数揭示的是变量与函数的关系,是对数学动态的研究过程.虽说初中函数知识较为简单、基础,但其中不乏数学思想与数学方法,对学生学科素养的培养有着重要的作用.同时,函数还是联系代数与几何的桥梁,通过直角坐标系的使用可以帮助学生清晰
Function is the focus and difficulty of junior high school mathematics teaching, students grasp the function of good or bad knowledge of the function of the students in the future have an important impact on the function of junior high school through the teaching function, you can train students to observe, analyze and solve problems, It is also helpful to the cultivation of students’ math learning habits.The junior middle school function reveals the relationship between variables and functions and is the research process of mathematics dynamics.Although the knowledge of junior high school functions is simple and basic, there are many mathematical ideas and mathematical methods, The cultivation of students’ academic quality plays an important role, meanwhile, the function is also a bridge linking algebra and geometry. The use of Cartesian coordinate system can help students to clear
