初中阶段所涉及的化学用语主要包括以下几类:元素符号、离子符号、化合价、化学式以及化学方程式.这些符号是学习化学的基础,也是教学重心,更是教学的难点、学生学习的瓶颈.学生只有熟练掌握此类用语才能提高化学成绩,反之,若对化学用语的掌握不够透彻,便会逐步掉队,对化学学习充满畏惧,最后失去学习化学的兴趣和信心.因此,学好化学用语也就成为了初中化学教育最重要的一步.以下是笔者对化学用语教学的几点简单总结和感悟.
The chemical terms involved in junior high school mainly include the following categories: element symbols, ionic symbols, valences, chemical formulas and chemical equations.These symbols are the basis of learning chemistry, but also teaching focus, but also the teaching difficulties, bottlenecks in student learning. Only by mastering these terms can we improve our chemistry. On the contrary, if we fail to grasp the chemical terms sufficiently, we will be left behind gradually, fearful of chemical learning, and finally lose the interest and confidence in learning chemistry. Therefore, learning chemical terms becomes The junior high school chemistry education is the most important step.The following is the author of chemical language teaching a few simple summary and insights.
