安徽省芜湖市一中李广群认为在初中阶段,化学方程式被定义为“用分子式来表示化学反应的式子”(初三化学课本p51),而多年来,在高中教材中,并没有随着知识的深化和扩展给化学方程式以适应新知识新情况的定义,造成上述初中时的定义不得不沿用到高中各学年的化学教学中去的被动状况。
Li Guangqun, one of Wuhu City, Anhui Province, believed that in the junior high school stage, the chemical equation was defined as “a formula to represent the chemical reaction equation” (3rd grade chemistry textbook, p51). For many years, in high school textbooks, there was no knowledge. The deepening and expansion of chemical equations to adapt to the definition of the new situation of new knowledge, resulting in the above-mentioned definition of junior high school had to follow the passive state of chemistry teaching in senior high school years.
