化学是一门以实验为基础的自然科学,其最大特点是学生动手实践的机会多,易激发学生的学习兴趣,实验内容现象及其变化规律,有利于引导学生去探索和思考。在教学中,充分利用化学学科“以实验为基础”的基本特征,要特别注意恢复实验的探究本性,提倡通过实验观察发现问题,通过实验展开探究活动,通过实验来检验知识、发展知识。但是,长期以来在中学化学教学中,实验往往异化为一种形式失去了它的探索功能,严重地影响了学生的质量和积极性,所以应该加强化学实验教学进行研究性学习发 Chemistry is an experiment-based natural science. The most prominent feature of chemistry is that students have more chances to practice. It is easy to stimulate students' interest in learning, the content of experiment and its changing rules, which helps to guide students to explore and think. In teaching, take full advantage of the chemical discipline “experimental basis ” the basic characteristics, pay special attention to the recovery of the nature of the inquiry, to promote the discovery of problems through experimental observation, through experiments to explore activities, through experiments to test and develop knowledge . However, for a long time, in chemistry teaching in middle school, experiment often alienated as a form lost its exploring function, which seriously affected the quality and enthusiasm of students. Therefore, we should strengthen the chemistry experiment teaching
