在进行高中物理力学的复习时,为了培养学生综合运用基础知识和实验能力,我安排了一次探索性的实验课。这次实验是参考高中物理甲种本第一册p.364的课外实验活动“估测自行车受到的阻力”来进行的。为了便于启发学生开动脑筋、相互学习,我将上述实验的研究对象作了修改。具体作法如下: 实验题目:估测物理小车在水平面上运动所受的平均阻力。实验目的:培养学生分析和解决实际问题的能力和实验能力。实验器材:物理小车(质量已知)、直尺,
In the review of high school physics and mechanics, in order to train students to use basic knowledge and experimental abilities comprehensively, I arranged an exploratory experimental course. This experiment was conducted with reference to the extracurricular experimental activity of the first grade p. In order to make it easier to inspire students to use their brains and learn from each other, I modified the subject of the above experiment. The specifics are as follows: Experiment title: Estimate the average resistance of the physical trolley to movement on the horizontal plane. Purpose of the experiment: To develop students’ ability to analyze and solve practical problems and experimental ability. Experimental equipment: physical trolley (known quality), ruler,
