粤教版高中物理必修I第二章第一节是“探究自由落体运动”。这节课我按照正常的教学设计来组织教学,在授完各个知识环节后距离下课还有两分钟,还再讲点什么呢?突然间我想起前段时间在网上看到的一则小故事。故事讲述的是两个人在讨论书和纸同时从同一高度下落谁下落得快,A君在 The first section of the second chapter of the compulsory version I of the Cantonese version of Physical Education I is “Inquiry into the Freefall Movement”. In this class, I organized the teaching according to the normal teaching design. After I had finished each knowledge session, I still had two minutes away from the class. What else did I say? Suddenly I remembered a small story I saw on the Internet some time ago. The story tells the story of two people who were talking about books and paper while falling from the same height and who was falling fast.
