物理学是一门以实验为基础的自然科学,物理规律都是在实验的基础上总结、归纳出来的.作为初中物理教师,在教学过程中,为得出某个规律或知识要点,经常会进行多次的演示实验或指导学生进行实验.所做的实验,其目的性都很强,都是为了达到相应的目的、得出相应的规律而进行的,因此我们当然希望实验的现象如我们所预期的那样.事实上,在实际的教学过程中,经常听到老师说到实验的失败了,找一些冠冕堂皇的理由向学生解释一下,最后将做实验变成了讲实验,教学效果就大打折扣了.那么,作为一名中学物理教师,如何才能科学合理的进行实验,从而确保 Physics is an experiment-based natural science, the laws of physics are summarized on the basis of the experiment.As a junior high school physics teacher, in the teaching process, in order to draw a law or knowledge points, often Conduct many demonstration experiments or guide students to experiment.The experiments that are done are of great purpose, all aim at reaching the corresponding purpose and drawing corresponding laws, therefore, we certainly hope that the phenomenon of experiment, such as us In fact, in the actual teaching process, teachers often hear the failure of the experiment, to find some sound reasons to explain to the students, and finally make the experiment into an experiment, the teaching effect is large Discount, so, as a physics teacher in middle school, how to conduct scientific and reasonable experiments to ensure
