“原电池”教学30年演进研究

Study on the Evolution of “Primary Battery” Teaching in Recent 30 Years

以近30年"原电池"(第1课时)的教学文献为研究对象,分析其教学演进过程。结果表明,随着化学课程改革进程,"原电池"核心教学内容、基本认识模型及教学实验具有相对稳定性,教学理念、目标、方法、内容组织及实验形式等在合理传承的基础上也在不断超越,呈现出渐进性变革的特征。但仍存在三维目标割裂设计、Cu-Zn原电池模型易衍生错误概念及学生探究活动仍存在浅层化等问题,需要在核心素养时代背景下研究解决。

Taking the teaching literatures of "galvanic battery"(lesson 1) for recent 30 years as the object of study, this paper analyzed the teaching evolution process of "galvanic battery"(lesson 1). The results shown that with the reform of chemistry curriculum, the core teaching content, basic knowledge model and teaching experiment of "primary battery" shown little change while the teaching idea, object, method, the way of content organization and experimental style had been transcending the past on the basis of reasonable inheritance, showing the characteristics of gradual change. However, there were still some problems need to be solved in the background of the era of key competence, such as three-dimensional target splitting design, error concepts easily derived from copper-zinc galvanic cell model and shallow exploration activities of students and so on.
