化学是一门以实验为基础的学科,可以说化学中的一切知识都来自于科学的化学实验.化学实验是活学活用化学知识的重要手段,同时又给学生提供了体验、探究、发展的机会,学生通过实验能系统验证化学基本原理,获取化学知识与技能,这对提高教学质量,培养学生的综合素质具有十分重要的作用.初中化学知识与日常生活联系紧密,为化学实验提供了便利条件.但目前,有些教师为了节省时间,忽视了化学实验操作,以“讲实验”、“背实验”的模式进行教学,将“活”的化学实验变成
Chemistry is an experiment-based discipline, it can be said that all the knowledge in chemistry comes from the scientific chemistry experiment.Chemical experiment is an important means to learn to use chemical knowledge, at the same time, it provides students with the experience, exploration and development Opportunities, students can systematically verify the basic principles of chemistry through experiments, access to chemical knowledge and skills, which improve the quality of teaching and cultivate the overall quality of students has a very important role in junior high school chemistry knowledge and daily life are closely linked to facilitate chemical experiments However, at present, some teachers, in order to save time, neglect the operation of chemical experiment, teach in the mode of “experimenting” and “experimenting backwards”, change the experiment of “living” into
