元素符号、化学式和化学方程式—是学习化学知识的最为关键的环节,如果不好好学习这些知识,就无法在学习化学知识上得到进步。目前,应用的初中化学课、元素符号、分子式和化学方程式,这些知识一连串的进行讲解,使学生难以接受的。教师通过探索,利用有效的教学方法,能否顺利通过这个难关是关键。并且在下次的教学过程中,进行反复的练习,达到熟练掌握这些知识。
Elemental symbols, chemical formulas, and chemical equations - are the most crucial aspects of learning chemistry, and learning chemistry can not progress without learning the knowledge. Currently, the application of junior high school chemistry class, elemental symbols, molecular formulas and chemical equations, a series of these knowledge to explain, so that students unacceptable. By exploring and using effective teaching methods, teachers can successfully pass this difficult situation. And in the next teaching process, repeated exercises to achieve proficiency in this knowledge.
