化学是一门以实验为基础的自然科学。化学实验教学是化学教学中不可缺少的一部分,化学实验教学以其自身的优点不同于其他教学,在提高学生的认识水平、激发学生学习的兴趣、培养学生的综合素质、提高学生对知识的应用能力等方面都有其独到之处,而演示实验又是实验教学的基础,对于培养学生稳定的注意力、敏捷的观察力、形象的思维能力、强烈的学习兴趣、发展智力起了积极的作用,特别在新课程改革的背景下,化学实验教学更为突出。充分发挥其在教学中的作用,激发学生学习的兴趣、主动性和积 Chemistry is an experiment-based science. Chemistry experiment teaching is an indispensable part of chemistry teaching. Chemical experiment teaching is different from other teaching in its own advantages. It can improve student’s cognition level, arouse student’s interest in learning, cultivate students ’overall quality and students’ application of knowledge Ability and other aspects have their own uniqueness, but the demonstration experiment is the basis of experimental teaching, which plays a positive role in cultivating students’ steady attention, agile observation ability, thinking ability of image, strong interest in learning and developing intelligence , Especially in the context of the new curriculum reform, chemical experiment teaching is more prominent. Give full play to its role in teaching, to stimulate student interest in learning, initiative and product
