近年来,由于教学大纲和课本的不断修订,对理论联系实际问题越来越重视.但是,学生实践知识不足的问题,仍有待进一步解决.学生知识面窄、学得过死的现象仍很普遍,高考中也反映出许多学生会背定律却不能很好地解决实际问题.而且,化学教学不仅要为高考服务,还要培养多层次的人才,所以理论联系实际的问题仍需要进一步探讨和落实. In recent years, due to the continuous revision of the syllabus and textbooks, more and more emphasis has been placed on integrating theory with practice. However, the lack of practical knowledge of students still needs to be further solved. The phenomenon of students with narrow knowledge and learning to die is still common. The college entrance examination also reflects that many students will back up the law but can not solve the practical problems well. Moreover, chemistry teaching not only needs to serve the college entrance examination, but also to cultivate multi-level talents, so the problem of linking theory with practice still needs further exploration and implementation.
