摘要
结合高中化学“电解质的电离”中丰富的教学活动，以感知体验化、微观可视化、知识本源化、认识观念化和符号意义化为教学策略，丰富和深化宏观表征和微观表征，实现化学三重表征的高度融合。
Combined with the rich teaching activities of ＂ionization of electrolyte＂ in senior high school chemistry textbook, this paper took the following teaching strategies to enrich and deepen macro-and-micro representations, such as perception experiencing, visualization of microscopic, knowledge digging, understanding to big ideas, and symbol elaboration, etc, and achieved the high degree of integration of triple representation of chemical symbols.
