化学是一门以实验为基础的学科。实验教学能激发学生学习化学的兴趣,帮助学生形成化学概念,获得化学知识和实验技能,培养观察和实验能力,还有助于培养实事求是、严肃认真的科学态度和学习方法;能迅速诱发学生学习化学的内在动力,帮助消化化学知识,掌握实验技能;同时启迪学生思维,体验科学探究,培养探究意识。化学实验改革是化学课程与教学改革的重要组成部分。下面笔者结合自己的教学实 Chemistry is an experiment-based discipline. Experimental teaching can stimulate students’ interest in learning chemistry, help students form chemical concepts, acquire chemical knowledge and experimental skills, develop observation and experimental skills, and also help cultivate practical, serious and scientific attitudes and learning methods; and can quickly induce students to learn. The intrinsic power of chemistry helps digest chemical knowledge and master experimental skills. At the same time, it inspires students to think, experience scientific inquiry, and cultivate inquiry consciousness. Chemical experiment reform is an important part of chemistry curriculum and teaching reform. The following author combines his teaching practice
