在课改的影响下,人们逐渐加大了对化学实验的重视,化学反应在高中化学中具有非常重要的作用,但是这个过程十分抽象,学生在理解中有一定困难.所以教师应通过化学反应原理,将实验知识形象化、具体化,并让学生在获得知识的同时,掌握相关技能和方法,提高学生的各项能力,学生能够在这个过程中掌握化学反应原理,更好的学习化学知识.一、重视化学演示实验,培养学生的实验方法在化学课堂中,演示实验是教师经常选用的教学方式.演
Under the influence of curriculum reform, people pay more attention to chemical experiments, and chemical reactions play a very important role in high school chemistry. However, this process is very abstract and students have some difficulties in understanding.Therefore, teachers should make use of chemical reactions Principle, the experimental knowledge visualization, specific, and allow students to acquire knowledge at the same time, master the relevant skills and methods to improve students’ abilities, students can master the chemical reaction principle in this process, to better learn the chemical knowledge First, attach importance to chemical demonstration experiments, experimental methods of training students In the chemistry class, demonstration experiments are often used by teachers teaching methods.
