在初中化学教学中,化学用语教学既是重点,又是难点,化学用语主要包括元素符号,原子、分子和离子,化学式和化合价,化学方程式等,这些知识通常是教师讲的枯燥无味,学生听的有气无力,学生不容易理解和掌握。因此,在初中化学用语教学中,应采用反复练习、巩固复习、归类比较、归纳总结等方法,化繁为简,化难为易,使学生对化学用语容易接受并能灵活使用。
In the junior high school chemistry teaching, the chemical language teaching is not only the key but also the difficult point. The chemical language mainly includes the element symbol, the atom, the molecule and the ion, the chemical formula and the valence value, the chemical equation and so on. These knowledge are usually the teacher is boring, , Students are not easy to understand and master. Therefore, in the junior high school chemistry language teaching, repeated practice should be adopted to consolidate the methods of reviewing, classifying and comparing, summarizing and summarizing. It will make the students easy to learn and to use the chemical language easily.
