物理学是一门以实验为基础的学科,物理教学要求理论与实验相结合.但仅仅照书本让学生模仿做一下实验,显然是不够的.我们不仅要去做实验,更要拓展延伸其功能,不断提高学生的创新意识和实践能力.在指导学生“用单摆测定重力加速度”的实验教学中,除了实验原理的探究、实验器材的选取、实验方法的确定(包括摆长的测量和周期的测定)、实验误差分析外,我还引导学生在实验后进行了再思考.问题1 若实验中误将圆锥摆当成单摆,测出的
Physics is an experiment-based discipline, and physics teaching requires a combination of theory and experiment, but it is obviously not enough to just copy books for students to imitate the experiment. Not only do we need to experiment, but also extend its function , And constantly improve the students’ innovative awareness and practical ability.In the experimental teaching of “guiding the students to determine the gravitational acceleration with pendulum”, in addition to the exploration of experimental principle, the selection of experimental equipment, the determination of experimental methods And the cycle of measurement), experimental error analysis, I also guide the students to rethink after the experiment.If the experiment mistakenly put the cone pendulum as a single pendulum, measured
