众所周知,化学实验在化学教学中占有重要的地位,加强实验教学是提高化学成绩的关键。笔者结合自己多年的教学实践,谈谈几点肤浅的认识。一、转变思想观念,加大实验资源投入新课程虽然实施已经好几年了,但是旧的教学理念和教学方法却没有根本性转变。受应试教育的影响,不少学校存在着用演示实验代替分组实验,用讲实验、播放实验视频或录像等做法代替做实验的现象。其结果是:学生对化学学习感到枯燥乏味,无法利用有趣的化学反应现象去理解抽象的知识,不利于培养学生的观察分析能力,更不利于培养学生的创新意识。
As we all know, chemical experiments play an important role in chemistry teaching. Strengthening experimental teaching is the key to improving chemistry. The author combines his years of teaching practice, to talk about a few superficial understanding. I. Changing Ideas and Enlarging Experimental Resources Although the new curriculum has been implemented for several years, the old teaching philosophy and teaching methods have not fundamentally changed. Subject to the impact of exam-oriented education, there are many schools, there is the use of demonstration experiments instead of grouping experiments, speaking experiments, playing experimental video or video instead of doing experiments. The result is: students feel boring chemistry learning, can not use the phenomenon of interesting chemical reactions to understand the abstract knowledge is not conducive to the development of students ’ability of observation and analysis, but also not conducive to cultivating students’ sense of innovation.
