摘　　要：函数是中学数学的核心知识,函数概念是最为抽象的概念之一。新课标强调函数教学中要突出实例的作用。初中物理课程的学习正好为函数知识的学习提供丰富的物理情境,学生在熟悉的情境中经历具体函数的学习,将抽象的函数变为具象的实例;在实际情境中应用函数性质解决问题的过程中逐步掌握函数性质,更好地把握事物发展规律;跨学科的相互渗透拓展了函数知识学习的视野,同时节约时间,提高学习效率。Functions are core knowledge in secondary school mathematics.Function concepts are among the most abstract,and the new curriculum standards emphasize the importance of examples in function teaching.The study of junior high school physics provides a rich context for learning functions.Students experiencing the study of specific functions in familiar scenarios can transform abstract functions into concrete examples.By applying functional properties to solve problems in real-life situations,students gradually grasp the nature of functions,better understanding the laws of development of things,the interdisciplinary penetration expands the vision of function knowledge learning,and also saves time and improve learning efficiency.
