天花板落地与飞机上天,听起来是风马牛不相及的事,一个向下,一个向上,是两种完全不同的运动。但仔细研究起来却有共同的原因。在日常的教学中,怎样培养学生的观察能力、探究能力、迁移能力和创造能力?怎样由己知的现象推证出学生未知的规律?这方面很值得我们去探讨。在这方面我做了一次尝试。 一次,高中物理兴趣小组活动时,突然狂风大作,大雨倾盆。因未来得及关窗,靠近窗口的几块吊顶天花板掉下来了,而远离窗口的却一块也没掉。这个“危险”的物理现象,其实大有文章可做。我灵活机动地一步步引导启发学生用学过的物理知识,推出学生没有学过的“空气流速增大,压强减小”的结论。下面是师生共同 The landing of the ceiling and the heavenly sky of the plane sounds like nothing else. One down and one up are two completely different sports. However, there are common reasons for careful study. In daily teaching, how to develop students’ observation ability, inquiry ability, migration ability and creative ability? How to deduce the unknown law of students from the known phenomenon? This aspect is worth our discussion. I made a try in this respect. On one occasion, when the high school physics interest group took part in the activity, a sudden torrential wind blew with heavy rain. Due to the need to close the window in the future, a few ceilings near the window fell off, but the one that was far away from the window did not fall. This “dangerous” physical phenomenon actually has a lot of articles to do. I flexibly and steadily guided the students to use the physics knowledge they had learned, and introduced the conclusion that students have not learned “the air flow rate increases, the pressure decreases”. The following is a common teacher and student
