化学是一门“以实验为基础”的科学,化学实验对化学课程目标的全面落实,培养学生科学思维、养成科学习惯和学习科学方法等有独特作用。化学实验是培养学生学习兴趣、观察能力、思维能力和动手能力的重要途径。实验教学效果直接影响学生化学素养的培养。因此,化学实验教学改革成为新课改的一种刚性需求。 Chemistry is an “experiment-based” science and chemistry experiment that has a unique effect on the full implementation of chemistry curriculum objectives, developing students’ scientific thinking, developing scientific habits and learning scientific methods. Chemistry experiment is to cultivate students interest in learning, observation ability, thinking ability and ability of an important way. The effect of experimental teaching directly affects the cultivation of students’ chemical literacy. Therefore, the reform of chemistry experiment teaching has become a rigid demand of the new curriculum reform.
