2025年教学资料:3.4函数的应用
授课题目3.4函数的应用选用教材高等教育出版社《数学》(基础模块上册)授课时长2课时授课类型新授课教学提示本课将通过解决实际生活中的简单函数问题(一次函数、分段函数、二次函数),提高学生对于这三种函数的应用的意识.教学目标能根据具体的情境,选择恰当的函数模型表达问题中的函数关系,通过运算、推理得出的结论解释情境中的问题;能进一步明确数学建模的一般步骤,逐步提高数学抽象和数学建模等核心素养.教学重点简单函数模型的应用教学难点根据实际问题建立函数模型;二次函数模型的最值问题教学环节教学内容教师活动学生活动设计意图情境导入许多实际问题都可以通过建立函数模型来解决,函数模型是应用最广泛的数学模型之一....
