牛顿第一运动定律是研究力学问题的重要定律,也是分析日常生活现象的基础.但在教学实践中,对牛顿第一定律的理解和运用一直是初中物理教学的难点.原统编教材结构是以物理学发展史为线索,先讲亚里士多德的观点,再讲伽利略实验,最后讲牛顿的概括总结.按此结构进行教学,课上学生似乎也听得津津有味,点头称是,但一遇到具体问题进行分析判断却往往出现错误.对于判断题:“用力推桌上静止的小车,使小车运动起来,所以说物体有力才运动.”马上会有半数学生答“对”!你问他们:“这不是亚里士多德的观点吗?”学生却答:“是,没
Newton's first law of motion is an important law for the study of mechanical problems, and it is also the basis for analyzing everyday phenomena. However, in the teaching practice, the understanding and application of Newton's first law has always been a difficult point in junior high school physics teaching. The original textbook structure is Taking the history of the development of physics as a clue, first talk about Aristotle's point of view, then talk about Galileo's experiment, and finally talk about Newton's summary. According to this structure for teaching, students in the class seem to hear a lot, nod their heads, but When you encounter a specific problem, you often get an error when analyzing and judging. For the judgment question: ”Hardly push the stationary car on the table to make the car move up, so that the object is powerful enough to move. “ Half of the students will answer immediately.” You asked them: “Isn't this Aristotle's point of view?” The student answered: "Yes, no
