一、创设实验情景,激发学生兴趣从学的角度来看,想要获得课堂教学的成功,则必须有一个良好的教学情境。愉快的教学,可以为学生提供一个更加良好的学习氛围,从而激发学生的求知欲,让学生的思维可以更加活跃,从而提高课堂教学的效率。演示实验就可以起到激发学生兴趣,调动学生学习积极性的作用。例如在讲解“频率”的概念时,可以为学生设计一个测试自己单位时间内脉搏跳动的实验,题目提出来,让学生自己想办法。这个问题比较简单,同时实施起来也比较容易,所以很容易调动学生积极性,同时由于没有现成方法,所以还 First, the creation of experimental scenarios to stimulate student interest From the school’s point of view, you want to get the success of classroom teaching, you must have a good teaching situation. Pleasant teaching can provide students with a better learning environment, which can stimulate students’ curiosity and make their thinking more active, so as to improve the efficiency of classroom teaching. Demonstration experiment can play a role in stimulating students’ interest and arousing the enthusiasm of students. For example, when explaining the concept of “frequency”, you can design an experiment for students to test their pulse rate in unit time. The questions should be raised so that students can find solutions by themselves. This problem is relatively simple, but also easier to implement, it is easy to mobilize the enthusiasm of students, but also because there is no ready-made method, so also
