摘要
在调查分析高三学生对原电池原理的理解及应用状况的基础上,论述了从电极电势及平衡移动的角度理解原电池中产生持续电流的原因,有助于学生能量观的建构及学生能力的发展。以高三原电池复习教学为例,阐述了促进学生理解学科知识本质的探究活动的设计。
Based on the investigation and analysis of 12th-grade students＇ understanding and applications of primary battery principles, this paper proposed that it was necessary for students to understand why continuous current was generated in a primary battery from the perspective of electrode potential and mobile equilibrium, which was helpful to develop students＇ energy view and ability. Taking review lessons on primary battery as an example, this study demonstrated the design of inquiry activities that promoted students to understand the essence of subject knowledge.
