基于数学建模的函数大单元教学设计:热水放冰箱多久才能冰冰凉

Teaching Design of Large-unit of Functions Based on Mathematical Modeling:How Long does it Take for Hot Water to be Cold in the Refrigerator

以“热水放冰箱多久才能冰冰凉”为背景,将数学建模与日常教学有机融合,对函数章节进行大单元教学设计.按照“学情分析和学习目标”“大单元教学过程设计”和“教学反馈与反思”的顺序,展示高中数学建模与大单元教学相结合的全过程,为一线教学实践提供经验和方法的借鉴.

Based on the background of"how long does it take for hot water to be cold in the refrigerator",this paper organically integrates mathematical modeling with daily teaching,and carries out a large-unit teaching design for the function chapter.According to the sequence of"learning situation analysis and learning objectives","design of large unit teaching process"and"teaching feedback and reflection",the whole process of combining high school mathematical modeling and large unit teaching is displayed,so as to provide experience and methods for front-line teaching practice.
