“实验探究教学方法”就是在教师指导下,以实验为基础,以探究为红线,学生通过实验操作、观察来研究认识物理现象,认知物理过程,探究物理规律,从而获得物理知识,形成技能,同时使学生的智力得到发展的一种教学方法.“自由落体运动”是高中物理“直线运动”一章的重要的一节课,是匀变速直线运动规律的典型应用.教材通过举例引出物体下落快慢与重力关系的讨论,并通过“毛钱管”实验得出自由落体运动的概念.然后在观察自由落体闪光照片的基础上,定性分析得出物体越落越快,即物体做加速运动,并没有进行定量分析,直接援引伽利略的研究结果,给出了自由落体运动是初速度为零的匀加速直线运动,并且给出了重力加速度的大小为9.8 m/s~2,方向是竖直向下的.从教学形式和教材编写上看,整个过程有举例、设问、讨论、实验和分析.但从知识的形成过程可以看 Under the guidance of teachers, based on the experiment, the inquiry is the red line, the students through the experimental operation, observation to study and understand the physical phenomena, cognitive physical processes, to explore the laws of physics, in order to obtain physical knowledge, Form a skill, at the same time make the student’s intelligence developed a teaching method. “Free Fall Movement ” is a high school physics “linear motion ” an important lesson, is a typical application of uniform variable speed linear motion The textbook leads to the discussion of the relationship between the drop speed and the gravity through the example and the concept of free falling body motion is obtained through the experiment of “gross money tube” experiment.And then on the basis of observing the flash photograph of the free falling body, The faster, the object accelerates, and without quantitative analysis, it directly invokes Galileo’s research. It shows that the free-fall motion is a uniformly accelerated linear motion with an initial velocity of zero, and the magnitude of the gravitational acceleration is 9.8 m / s ~ 2, the direction is vertical downward.From the teaching forms and teaching materials on the point of view, the whole process has examples, set questions, discussion, experiment and analysis.But from the formation of knowledge can see
