一、导语设计:由对生命意义的讨论导入新课同学们,首先让我们做一道非常简单的数学应用题,请大家注意听:自从我们降生,就开始拥有了生命,假设我们的平均寿命是72岁,那么请同学们回答一下,你大约已经度过了几分之几的人生? 好,在座的每位同学已经走完了六分之一的人生旅途,那么,大家考虑过这样一个问题没有,即我们应该如何度过自己的一生呢?下面请同学们以自己为例,展开讨论,然
I. Leading Word Design: Introducing the new lesson from the discussion of the meaning of life. Let’s start with a very simple application of mathematics. Please note that since we were born, we began to have a life. Assuming that our average life expectancy is At the age of 72, then ask the students to answer. Have you already spent a fraction of your life? Well, every classmate in this room has already gone through a one-sixth life journey. Well, everyone thought about this problem. , that is, how should we spend our own life? Next, ask the students to use their own example as a starting point for discussion.
