化学是一门以实验为基础的学科,基本上所有的化学理论都是在实验的基础上总结出来的,高中化学新课标也明确指出要通过化学教学活动培养学生的实验能力.实验教学是高中化学教学中一个非常重要的环节,是高中化学课程的重要组成部分,是引导学生科学探究的重要途径,因此,高中化学教学中必须重视化学实验教学.但教学实践中一些教师为了节省课堂时间,忽视实验教学,注重知识点讲解,将做实验变成了讲实验,学生缺少动手操作的机会.教师要积极改变教学方法,充分利用演示实验和学生实验
Chemistry is an experiment-based discipline. Basically, all chemical theories are summed up on the basis of experiments. The new high school chemistry curriculum also clearly points out that students’ experimental abilities must be cultivated through chemistry teaching activities. Experimental teaching is A very important part of high school chemistry teaching is an important part of the high school chemistry curriculum, which is an important way to guide students in scientific inquiry. Therefore, high school chemistry teaching must pay attention to chemistry experiment teaching. However, some teachers in teaching practice in order to save time in class , Ignore experimental teaching, pay attention to the explanation of knowledge, change the experiment into an experiment, and students lack opportunities for hands-on operation. Teachers should actively change teaching methods, make full use of demonstration experiments and student experiments.
