化学基本概念是初中学生难以掌握的重要内容之一,初中化学基本概念比较多、而且很抽象。学生对基本概念的理解与掌握程度关系到后期化学课程学习的难易度。只有深入地理解了有关的化学概念,才能学好化学原理、元素化合物知识、化学计算及化学基本实验。 The basic concept of chemistry is one of the most important contents difficult to be learned by junior high school students. The basic concepts of junior high school chemistry are more and more abstract. Students’ understanding and mastery of basic concepts are related to the difficulty of learning chemistry in the later period. Only in-depth understanding of the relevant chemical concepts in order to learn the principles of chemistry, chemical compounds and basic knowledge of chemical experiments.
